Acquisition and Divestiture Activities [Abstract]
Acquisition and Divestiture Activities	Note 2 – Acquisition Activities As part of its growth strategy, the Company seeks to expand through targeted acquisitions of other manufacturers of electronic components that have established positions in major markets, reputations for product quality and reliability, and product lines with which the Company has substantial marketing and technical expertise. In the fourth fiscal quarter of 2015, the Company deposited the $6,750 purchase price of Sonntag Electronic GmbH ("Sonntag"). The purchase price, net of cash acquired was $5,450. The acquisition was effective January 1, 2016. Sonntag is a distributor of electronic components in Germany. The inclusion of this business did not have a material impact on the Company's consolidated results for the fiscal quarter or six fiscal months ended July 2, 2016. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $3,485 related to this acquisition. The goodwill related to this acquisition is included in the Resistors & Inductors reporting unit for goodwill impairment testing. Had this acquisition occurred as of the beginning of the periods presented in these consolidated condensed financial statements, the pro forma statements of operations would not be materially different than the consolidated condensed statements of operations presented. The remaining fluctuation in the goodwill account balance is due to foreign currency translation.

Restructuring and Related Activities [Abstract]
Restructuring and Related Activities	Note 3 – Restructuring and Related Activities The Company places a strong emphasis on controlling its costs and combats general price inflation by continuously improving its efficiency and operating performance. When the ongoing cost containment activities are not adequate, the Company takes actions to maintain its cost competitiveness. The Company incurred significant restructuring costs in its past to reduce its cost structure. Historically, the Company's primary cost reduction technique was through the transfer of production from high-labor-cost countries to lower-labor-cost countries. Since 2013, the Company's cost reduction programs have primarily focused on reducing fixed costs, including selling, general, and administrative expenses. In 2013, the Company announced various cost reduction programs. These programs were substantially implemented by the end of the first fiscal quarter of 2016, with some additional costs incurred in the second fiscal quarter of 2016. Many of the severance costs were recognized ratably over the required stay periods. In 2015, the Company announced additional global cost reduction programs. These programs include a facility closure in the Netherlands. The cash costs of these programs, primarily severance, are expected to aggregate to approximately $30,000. Complete implementation of these programs is expected to occur before the end of 2017. The following table summarizes restructuring and related expenses which were recognized and reported on a separate line in the accompanying consolidated statements of operations: Fiscal quarters ended Six fiscal months ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 MOSFETs Enhanced Competitiveness Program $ 1,110 $ 939 $ 5,025 $ 2,292 Voluntary Separation / Retirement Program - 20 - 77 Modules Production Transfer Program - - - - Global Cost Reduction Programs 3,357 4,701 5,917 4,701 Total $ 4,467 $ 5,660 $ 10,942 $ 7,070 MOSFETs Enhanced Competitiveness Program Over a period of approximately 2 years and in a series of discrete steps, the manufacture of wafers for a substantial share of products was transferred into a more cost-efficient fab. As a consequence, certain other manufacturing currently occurring in-house was transferred to third-party foundries. The transfer of production was substantially completed by the end of the first fiscal quarter of 2016. Employees generally were required to remain with the Company during the production transfer period. Accordingly, the Company accrued these severance costs ratably over the respective employees' remaining service periods. The Company has incurred and may continue to incur other exit costs associated with the production transfer, including certain contract termination costs. The Company continues to evaluate the performance of its MOSFETs segment and potential cost reduction opportunities. The following table summarizes the activity to date related to this program: Expense recorded in 2013 $ 2,328 Cash paid (267 ) Balance at December 31, 2013 $ 2,061 Expense recorded in 2014 6,025 Cash paid (856 ) Balance at December 31, 2014 $ 7,230 Expense recorded in 2015 5,367 Cash paid (426 ) Foreign currency translation 1 Balance at December 31, 2015 $ 12,172 Expense recorded in 2016 5,025 Cash paid (10,327 ) Foreign currency translation 3 Balance at July 2, 2016 $ 6,873 Severance benefits are generally paid in a lump sum at cessation of employment. Other exit costs of $4,352 are included in the expenses incurred in 2016 in the table above. The entire amount of the liability is considered current and is included in other accrued expenses in the accompanying consolidated condensed balance sheets. Voluntary Separation / Retirement Program The voluntary separation / early retirement program was offered to employees worldwide who were eligible because they met job classification, age, and years-of-service criteria as of October 31, 2013. The program benefits varied by country and job classification, but generally included a cash loyalty bonus based on years of service. All employees eligible for the program have left the Company. These employees generally were not aligned with any particular segment. The effective separation / retirement date for most employees who accepted the offer was June 30, 2014 or earlier, with a few exceptions to allow for a transition period. The following table summarizes the activity to date related to this program: Expense recorded in 2013 $ 486 Cash paid (98 ) Foreign currency translation 3 Balance at December 31, 2013 $ 391 Expense recorded in 2014 12,792 Cash paid (8,054 ) Foreign currency translation (455 ) Balance at December 31, 2014 $ 4,674 Expense recorded in 2015 95 Cash paid (3,166 ) Foreign currency translation (258 ) Balance at December 31, 2015 $ 1,345 Cash paid (621 ) Foreign currency translation 20 Balance at July 2, 2016 $ 744 The payment terms vary by country, but generally are paid in a lump sum at cessation of employment. Certain participants are being paid in installments. The entire amount of the liability is considered current and is included in other accrued expenses in the accompanying consolidated condensed balance sheets. Modules Production Transfer In an effort to reduce costs and streamline production of its module products within its Diodes segment, the Company committed to two smaller cost reduction programs related to the transfer of production of certain of its products. The following table summarizes the activity to date related to this program: Expense recorded in 2014 $ 2,080 Cash paid (464 ) Foreign currency translation (121 ) Balance at December 31, 2014 $ 1,495 Cash paid (718 ) Foreign currency translation (120 ) Balance at December 31, 2015 $ 657 Cash paid (10 ) Foreign currency translation 13 Balance at July 2, 2016 $ 660 Severance benefits are generally paid in a lump sum at cessation of employment. The entire amount of the liability is considered current and is included in other accrued expenses in the accompanying consolidated condensed balance sheets. Global Cost Reduction Programs The global cost reduction programs announced in 2015 include a plan to reduce selling, general, and administrative costs company-wide, and targeted streamlining and consolidation of production for certain product lines within its Capacitors and Resistors & Inductors segments. The following table summarizes the activity to date related to this program: Expense recorded in 2015 $ 13,753 Cash paid (986 ) Foreign currency translation (150 ) Balance at December 31, 2015 $ 12,617 Expense recorded in 2016 5,917 Cash paid (7,972 ) Foreign currency translation (160 ) Balance at July 2, 2016 $ 10,402 The following table summarizes the expense recognized in 2016 by segment related to this program: Diodes $ 578 Optoelectronic Components 953 Resistors & Inductors 2,522 Capacitors 423 Unallocated Selling, General, and Administrative Expenses 1,441 Total $ 5,917 Severance benefits are generally paid in a lump sum at cessation of employment. The current portion of the liability is $7,927 and is included in other accrued expenses in the accompanying consolidated condensed balance sheets. The non-current portion of the liability is included in other liabilities in the accompanying consolidated balance sheets.

Income Taxes

Income Taxes [Abstract]
Income Taxes	Note 4 – Income Taxes The provision for income taxes consists of provisions for federal, state, and foreign income taxes. The effective tax rates for the periods ended July 2, 2016 and July 4, 2015 reflect the Company's expected tax rate on reported income from continuing operations before income tax and tax adjustments. The Company operates in a global environment with significant operations in various jurisdictions outside the United States. Accordingly, the consolidated income tax rate is a composite rate reflecting the Company's earnings and the applicable tax rates in the various jurisdictions where the Company operates. Income tax expense for the fiscal quarter and six fiscal months ended July 2, 2016 includes the remeasurement of the deferred tax liability recorded for the cash repatriation program announced in the fourth fiscal quarter of 2015 of $1,217 and $1,986, respectively. During the second fiscal quarter of 2016, the Company repatriated $46,000 pursuant to this program. During the six fiscal months ended July 2, 2016, the liabilities for unrecognized tax benefits increased by $140 on a net basis, principally due to increases for tax positions taken in prior periods, interest, and foreign currency effects, partially offset by payments and settlements.

The quarterly cash dividend program of the Company results in adjustments to the conversion rate and effective conversion price for each issuance of the Company's convertible senior debentures effective as of the ex-dividend date of each cash dividend. The following table summarizes some key facts and terms regarding the three series of outstanding convertible senior debentures following the adjustment made to the conversion rate of the debentures on the ex-dividend date of the June 29, 2016 dividend payment: Due 2040 Due 2041 Due 2042 Issuance date November 9, 2010 May 13, 2011 May 31, 2012 Maturity date November 15, 2040 May 15, 2041 June 1, 2042 Principal amount $ 275,000 $ 150,000 $ 150,000 Cash coupon rate (per annum) 2.25 % 2.25 % 2.25 % Nonconvertible debt borrowing rate at issuance (per annum) 8.00 % 8.375 % 7.50 % Conversion rate effective June 13, 2016 (per $1 principal amount) 75.4595 55.0664 88.7223 Effective conversion price effective June 13, 2016 (per share) $ 13.25 $ 18.16 $ 11.27 130% of the conversion price (per share) $ 17.23 $ 23.61 $ 14.65 Call date November 20, 2020 May 20, 2021 June 7, 2022 Prior to three months before the maturity date, the holders may only convert their debentures under the following circumstances: (1) during any fiscal quarter after the first full quarter subsequent to issuance, if the sale price of Vishay common stock reaches 130% of the conversion price for a specified period; (2) the trading price of the debentures falls below 98% of the product of the sale price of Vishay's common stock and the conversion rate for a specified period; (3) Vishay calls any or all of the debentures for redemption, at any time prior to the close of business on the third scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. Based on an evaluation of the conversion criteria at July 2, 2016 and December 31, 2015, none of the convertible senior debentures due 2040, due 2041, or due 2042 were convertible. The conversion criteria of the debentures will continue to be evaluated and the debentures may become convertible in the future. At the direction of the Company's Board of Directors, the Company intends, upon conversion, to repay the principal amount of the convertible debentures in cash and settle any additional amounts in shares of the Company's common stock. The Company intends to finance the principal amount of any converted debentures using borrowings under its credit facility. GAAP requires an issuer to separately account for the liability and equity components of the instrument in a manner that reflects the issuer's nonconvertible debt borrowing rate when interest costs are recognized in subsequent periods. The resulting discount on the debt is amortized as non-cash interest expense in future periods. The carrying values of the liability and equity components of the convertible debentures are reflected in the Company's consolidated condensed balance sheets as follows: Principal amount of the debentures Unamortized discount Embedded derivative Carrying value of liability component Equity component - net carrying value July 2, 2016 Due 2040 $ 275,000 (168,442 ) 541 $ 107,099 $ 110,094 Due 2041 $ 150,000 (95,441 ) 404 $ 54,963 $ 62,246 Due 2042 $ 150,000 (89,419 ) 271 $ 60,852 $ 57,874 Total $ 575,000 $ (353,302 ) $ 1,216 $ 222,914 $ 230,214 December 31, 2015 Due 2040 $ 275,000 (169,565 ) 576 $ 106,011 $ 110,094 Due 2041 $ 150,000 (96,014 ) 438 $ 54,424 $ 62,246 Due 2042 $ 150,000 (89,982 ) 302 $ 60,320 $ 57,874 Total $ 575,000 $ (355,561 ) $ 1,316 $ 220,755 $ 230,214 Interest is payable on the debentures semi-annually at the cash coupon rate; however, the remaining debt discount is being amortized as additional non-cash interest expense using an effective annual interest rate equal to the Company's estimated nonconvertible debt borrowing rate at the time of issuance. In addition to ordinary interest, contingent interest will accrue in certain circumstances relating to the trading price of the debentures and under certain other circumstances beginning ten years subsequent to issuance. Interest expense related to the debentures is reflected on the consolidated condensed statements of operations for the fiscal quarters ended: Contractual coupon interest Non-cash amortization of debt discount Non-cash amortization of deferred financing costs Non-cash change in value of derivative liability Total interest expense related to the debentures July 2, 2016 Due 2040 $ 1,547 567 22 (41 ) $ 2,095 Due 2041 $ 844 289 13 (72 ) $ 1,074 Due 2042 $ 844 283 14 (14 ) $ 1,127 Total $ 3,235 $ 1,139 $ 49 $ (127 ) $ 4,296 July 4, 2015 Due 2040 $ 1,547 524 22 165 $ 2,258 Due 2041 $ 844 267 12 124 $ 1,247 Due 2042 $ 844 263 14 46 $ 1,167 Total $ 3,235 $ 1,054 $ 48 $ 335 $ 4,672 Interest expense related to the debentures is reflected on the consolidated condensed statements of operations for the six fiscal months ended: Contractual coupon interest Non-cash amortization of debt discount Non-cash amortization of deferred financing costs Non-cash change in value of derivative liability Total interest expense related to the debentures July 2, 2016 Due 2040 $ 3,094 1,123 44 (35 ) $ 4,226 Due 2041 $ 1,688 573 24 (34 ) $ 2,251 Due 2042 $ 1,688 563 27 (31 ) $ 2,247 Total $ 6,470 $ 2,259 $ 95 $ (100 ) $ 8,724 July 4, 2015 Due 2040 $ 3,094 1,039 44 106 $ 4,283 Due 2041 $ 1,688 528 24 137 $ 2,377 Due 2042 $ 1,688 523 27 39 $ 2,277 Total $ 6,470 $ 2,090 $ 95 $ 282 $ 8,937 Exchangeable Unsecured Notes, due 2102 On June 28, 2016 and March 31, 2016, pursuant to agreements dated June 13, 2016 and March 10, 2016, respectively, the Company acquired from holders $12,436 and $26,206, respectively, principal amount of the Company's floating rate exchangeable unsecured notes due 2102. The purchase price for these privately negotiated transactions was $11,449 and $22,595, respectively. Vishay recognized gains on early extinguishment of debt of $986 and $4,597 presented as a separate line item in the accompanying consolidated condensed statements of operations for the fiscal quarter and six fiscal months ended July 2, 2016, respectively. The notes that Vishay repurchased in the fiscal quarter and six fiscal months ended July 2, 2016 had been exchangeable for 807,995 and 2,510,808 shares of Vishay common stock, respectively. Following the June 28, 2016 transaction, no exchangeable unsecured notes are outstanding.

Other Income (Expense) [Abstract]
Other Income (Expense)	Note 6 – Other Income (Expense) On August 12, 2015, a major explosion occurred in the port of Tianjin, China. Vishay owns and operates a diodes manufacturing facility in Tianjin near the port. The shockwave of the explosion resulted in some damage to the facility and caused a temporary shutdown. Full production resumed on September 8, 2015. As a result of this incident, through the end of the second fiscal quarter of 2016, the Company estimates that it has incurred $10,145 for inventory, property, and equipment damage (at net book value) and related repair and clean-up costs. The Company received a first payment of $716 for a portion of its inventory damage claim in the second fiscal quarter of 2016. As of July 2, 2016, the Company has recorded a receivable of $4,079 for amounts which are probable of recovery under its insurance policies. The Company recorded, as a separate line item, a loss related to these items in 2015, which represents the insurance deductible and certain costs which are potentially not recoverable. The Company's insurance coverage generally provides for replacement cost of damaged items. The insurance claims process continues as expected. Any amount expected to be received in excess of the book value of the damaged item will be treated as a gain, but will not be recorded until contingencies are resolved. The Company also believes that it has valid claims under its business interruption insurance policies, but those claims cannot be quantified at this time. The Company will not record a receivable for business interruption claims until all contingencies have been resolved.

Plan participants will not be adversely affected by the plan termination, but rather will have their benefits either converted into a lump sum cash payment or an annuity contract placed with an insurance carrier. The completion of this proposed termination and settlement is contingent upon the receipt of a favorable determination letter from the Internal Revenue Service ("IRS") and meeting certain IRS and Pension Benefit Guarantee Corporation ("PBGC") requirements, which is not expected to be received prior to the fourth fiscal quarter of 2016. As of the last fiscal year-end measurement date (December 31, 2015), the Vishay Retirement Plan was fully-funded on a GAAP basis. In order to terminate the plan in accordance with IRS and PBGC requirements, the Company is required to fully fund the plan on a termination basis and will commit to contribute the additional assets necessary to do so. The amount necessary to do so is not yet known, but is currently estimated to be between zero and $35,000. The Company contributed $16,966 to the Company's Taiwanese pension plans to improve the funded status of those plans in 2016. Other Postretirement Benefits The following table shows the components of the net periodic benefit cost for the second fiscal quarters of 2016 and 2015 for the Company's other postretirement benefit plans: Fiscal quarter ended July 2, 2016 Fiscal quarter ended July 4, 2015 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Service cost $ 32 $ 68 $ 30 $ 68 Interest cost 85 36 84 36 Amortization of prior service (credit) (209 ) - (209 ) - Amortization of losses (gains) (7 ) 17 23 19 Net periodic benefit cost $ (99 ) $ 121 $ (72 ) $ 123 The following table shows the components of the net periodic pension cost for the six fiscal months ended July 2, 2016 and July 4, 2015 for the Company's other postretirement benefit plans: Six fiscal months ended July 2, 2016 Six fiscal months ended July 4, 2015 U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans Service cost $ 63 $ 135 $ 60 $ 137 Interest cost 170 72 167 73 Amortization of prior service (credit) (418 ) - (418 ) - Amortization of losses (gains) (15 ) 34 45 38 Net periodic benefit cost $ (200 ) $ 241 $ (146 ) $ 248

Stock-Based Compensation [Abstract]
Stock-Based Compensation	Note 9 – Stock-Based Compensation The Company has various stockholder-approved programs which allow for the grant of stock-based compensation to officers, employees, and non-employee directors of the Company. The amount of compensation cost related to stock-based payment transactions is measured based on the grant-date fair value of the equity instruments issued. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The Company determines compensation cost for restricted stock units ("RSUs"), phantom stock units, and restricted stock based on the grant-date fair value of the underlying common stock adjusted for expected dividends paid over the required vesting period for non-participating awards. Compensation cost is recognized over the period that an officer, employee, or non-employee director provides service in exchange for the award. The following table summarizes stock-based compensation expense recognized: Fiscal quarters ended Six fiscal months ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 Restricted stock units $ 1,085 $ 924 $ 2,169 1,838 Phantom stock units - - 117 141 Stock options - - - - Total $ 1,085 $ 924 $ 2,286 1,979 The Company recognizes compensation cost for RSUs that are expected to vest and records cumulative adjustments in the period that the expectation changes. The following table summarizes unrecognized compensation cost and the weighted average remaining amortization periods at July 2, 2016 (amortization periods in years) Unrecognized Compensation Cost Weighted Average Remaining Amortization Periods Restricted stock units $ 6,387 1.5 Phantom stock units - 0.0 Stock options - 0.0 Total $ 6,387 The Company currently expects all performance-based RSUs to vest and all of the associated unrecognized compensation cost for performance-based RSUs presented in the table above to be recognized. 2007 Stock Incentive Plan The Company's 2007 Stock Incentive Program (the "2007 Program"), as amended and restated, permits the grant of up to 6,500,000 shares of restricted stock, unrestricted stock, RSUs, stock options, and phantom stock units, to officers, employees, and non-employee directors of the Company. Such instruments are available for grant until May 20, 2024. Restricted Stock Units RSU activity under the 2007 Program as of July 2, 2016 and changes during the six fiscal months then ended are presented below (number of RSUs in thousands) Number of RSUs Weighted Average Grant-date Fair Value per Unit Outstanding: January 1, 2016 1,028 $ 13.24 Granted 353 11.35 Vested* (142 ) 12.21 Cancelled or forfeited (222 ) 13.19 Outstanding at July 2, 2016 1,017 $ 12.74 Expected to vest at July 2, 2016 1,017 * The number of RSUs vested includes shares that the Company withheld on behalf of employees to satisfy the statutory tax withholding requirements. The number of performance-based RSUs that are scheduled to vest increases ratably based on the achievement of defined performance criteria between the established target and maximum levels. RSUs with performance-based vesting criteria are expected to vest as follows (number of RSUs in thousands) Vesting Date Expected to Vest Not Expected to Vest Total January 1, 2017 192 - 192 January 1, 2018 202 - 202 January 1, 2019 213 - 213 Phantom Stock Units The 2007 Program authorizes the grant of phantom stock units to the extent provided for in the Company's employment agreements with certain executives. Each phantom stock unit entitles the recipient to receive a share of common stock at the individual's termination of employment or any other future date specified in the applicable employment agreement. Phantom stock units participate in dividend distribution on the same basis as the Company's common stock and Class B common stock. Dividend equivalents are issued in the form of additional units of phantom stock. The phantom stock units are fully vested at all times. Phantom stock unit activity under the phantom stock plan as of July 2, 2016 and changes during the six fiscal months then ended are presented below (number of phantom stock units in thousands) Number of units Grant-date Fair Value per Unit Outstanding: January 1, 2016 132 Granted 10 $ 11.71 Dividend equivalents issued 2 Outstanding at July 2, 2016 144 Stock Options In addition to stock options outstanding pursuant to the 2007 Program, during the periods presented, the Company had stock options outstanding under previous stockholder-approved stock option programs. These programs are more fully described in Note 12 to the Company's consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2015. No additional options may be granted pursuant to these programs. At December 31, 2015 and July 2, 2016, there were 105,000 options outstanding with a weighted average exercise price of $15.38. At July 2, 2016, the weighted average remaining contractual life of all outstanding options was 0.83 years. At July 2, 2016, there were no unvested options outstanding. The pretax aggregate intrinsic value (the difference between the closing stock price on the last trading day of the second fiscal quarter of 2016 of $12.34 per share and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on July 2, 2016 was zero because all outstanding options have exercise prices in excess of market value. This amount changes based on changes in the market value of the Company's common stock. During the six fiscal months ended July 2, 2016, no options were exercised.

Segment Information [Abstract]
Segment Information	Note 10 – Segment Information Vishay operates, and its chief operating decision maker makes strategic and operating decisions with regards to assessing performance and allocating resources based on, five reporting segments: MOSFETs, Diodes, Optoelectronic Components, Resistors & Inductors, and Capacitors. The Company evaluates business segment performance on operating income, exclusive of certain items ("segment operating income"). Only dedicated, direct selling, general, and administrative expenses of the segments are included in the calculation of segment operating income. The Company's calculation of segment operating income excludes such selling, general, and administrative costs as global operations, sales and marketing, information systems, finance and administration groups, as well as restructuring and severance costs, goodwill and long-lived asset impairment charges, and other items. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company. These items represent reconciling items between segment operating income and consolidated operating income. Business segment assets are the owned or allocated assets used by each business. The following tables set forth business segment information: MOSFETs Diodes Optoelectronic Components Resistors & Inductors Capacitors Total Fiscal quarter ended July 2, 2016: Product Sales $ 102,219 $ 142,118 $ 68,059 $ 192,717 $ 84,856 $ 589,969 Royalty Revenues - - - 82 - $ 82 Total Revenue $ 102,219 $ 142,118 $ 68,059 $ 192,799 $ 84,856 $ 590,051 Gross Profit $ 11,884 $ 37,258 $ 21,618 $ 57,256 $ 18,112 $ 146,128 Fiscal quarter ended July 4, 2015: Product Sales $ 106,348 $ 138,722 $ 72,977 $ 178,786 $ 92,891 $ 589,724 Royalty Revenues - - - 746 - $ 746 Total Revenue $ 106,348 $ 138,722 $ 72,977 $ 179,532 $ 92,891 $ 590,470 Gross Profit $ 14,708 $ 31,600 $ 24,331 $ 53,342 $ 17,501 $ 141,482 Six fiscal months ended July 2, 2016: Product Sales $ 203,152 $ 277,502 $ 130,834 $ 376,133 $ 172,876 $ 1,160,497 Royalty Revenues - - - 160 - $ 160 Total Revenue $ 203,152 $ 277,502 $ 130,834 $ 376,293 $ 172,876 $ 1,160,657 Gross Profit $ 24,471 $ 69,920 $ 40,799 $ 113,040 $ 35,207 $ 283,437 Six fiscal months ended July 4, 2015: Product Sales $ 213,107 $ 275,233 $ 141,602 $ 365,178 $ 186,927 $ 1,182,047 Royalty Revenues 11 - - 1,848 - $ 1,859 Total Revenue $ 213,118 $ 275,233 $ 141,602 $ 367,026 $ 186,927 $ 1,183,906 Gross Profit $ 28,466 $ 61,490 $ 46,514 $ 112,191 $ 37,859 $ 286,520 Fiscal quarters ended Six fiscal months ended July 2, 2016 July 4, 2015 July 2, 2016 July 4, 2015 Operating margin reconciliation: MOSFETs $ 2,560 $ 5,140 $ 5,178 $ 9,667 Diodes 31,550 25,528 58,193 49,013 Optoelectronic Components 15,844 19,163 29,498 36,250 Resistors & Inductors 48,571 44,470 95,454 93,995 Capacitors 12,632 11,786 23,935 26,350 Restructuring and Severance Costs (4,467 ) (5,660 ) (10,942 ) (7,070 ) Unallocated Selling, General, and Administrative Expenses (57,282 ) (56,257 ) (111,360 ) (116,477 ) Consolidated Operating Income $ 49,408 $ 44,170 $ 89,956 $ 91,728

The Company's convertible debt instruments are only convertible for specified periods upon the occurrence of certain events. None of the conversion criteria were met for the periods presented. In periods that the debentures are not convertible, the certain conditions which could trigger conversion of the remaining debentures have been deemed to be non-substantive, and accordingly, the Company assumes the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive. At the direction of its Board of Directors, the Company intends, upon conversion, to repay the principal amounts of the convertible senior debentures, due 2040, due 2041, and due 2042, in cash and settle any additional amounts in shares of Vishay common stock. Accordingly, the debentures are included in the diluted earnings per share computation using the "treasury stock method" (similar to options and warrants) rather than the "if converted method" otherwise required for convertible debt. Under the "treasury stock method," Vishay calculates the number of shares issuable under the terms of the debentures based on the average market price of Vishay common stock during the period, and that number is included in the total diluted shares figure for the period. If the average market price is less than $13.25, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2040, if the average market price is less than $18.16, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2041, and if the average market price is less than $11.27, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2042.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 12 – Fair Value Measurements The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company's own assumptions. An asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented. The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis: Total Fair Value Level 1 Level 2 Level 3 July 2, 2016: Assets: Assets held in rabbi trusts $ 41,861 $ 27,768 $ 14,093 $ - Available for sale securities $ 4,144 4,144 - - $ 46,005 $ 31,912 $ 14,093 $ - Liabilities: Embedded derivative - convertible debentures due 2040 $ (541 ) $ - $ - $ (541 ) Embedded derivative - convertible debentures due 2041 $ (404 ) - - (404 ) Embedded derivative - convertible debentures due 2042 $ (271 ) - - (271 ) $ (1,216 ) $ - $ - $ (1,216 ) December 31, 2015: Assets: Assets held in rabbi trusts $ 39,849 $ 25,906 13,943 $ - Available for sale securities $ 3,604 3,604 - - $ 43,453 $ 29,510 $ 13,943 $ - Liabilities: Embedded derivative - convertible debentures due 2040 $ (576 ) $ - $ - $ (576 ) Embedded derivative - convertible debentures due 2041 $ (438 ) - - (438 ) Embedded derivative - convertible debentures due 2042 $ (302 ) - - (302 ) $ (1,316 ) $ - $ - $ (1,316 ) The Company maintains non-qualified trusts, referred to as "rabbi" trusts, to fund payments under deferred compensation and non-qualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the period. The company-owned life insurance assets are valued in consultation with the Company's insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy. The Company holds available for sale investments in debt securities that are intended to fund a portion of its pension and other postretirement benefit obligations outside of the United States. The investments are valued based on quoted market prices on the last business day of the year. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy. The convertible senior debentures, due 2040, due 2041, and due 2042, issued by the Company on November 9, 2010, May 13, 2011, and May 31, 2012, respectively, contain embedded derivative features that GAAP requires to be bifurcated and remeasured each reporting period. Each quarter, the change in the fair value of the embedded derivative features, if any, is recorded in the consolidated condensed statements of operations. The Company uses a derivative valuation model to derive the value of the embedded derivative features. Key inputs into this valuation model are the Company's current stock price, risk-free interest rates, the stock dividend yield, the stock volatility, and the debentures' credit spread over LIBOR. The first three aforementioned inputs are based on observable market data and are considered Level 2 inputs while the last two aforementioned inputs are unobservable and thus require management's judgment and are considered Level 3 inputs. The fair value measurement is considered a Level 3 measurement within the fair value hierarchy. The Company enters into forward contracts with a highly-rated financial institution to mitigate the foreign currency risk associated with intercompany loans denominated in a currency other than the legal entity's functional currency. The notional amount of the forward contracts was $114,000 and $29,000 as of July 2, 2016 and December 31, 2015, respectively. The forward contracts are short-term in nature and are expected to be renewed at the Company's discretion until the intercompany loans are repaid. We have not designated the forward contracts as hedges for accounting purposes, and as such the change in the fair value of the contracts is recognized in the consolidated condensed statements of operations as a component of other income (expense). The Company estimates the fair value of the forward contracts based on applicable and commonly used pricing models using current market information and is considered a Level 2 measurement within the fair value hierachy. The value of the forward contracts was immaterial as of July 2, 2016. The Company does not utilize derivatives or other financial instruments for trading or other speculative purposes. The fair value of the long-term debt, excluding the derivative liabilities and deferred financing costs, at July 2, 2016 and December 31, 2015 is approximately $687,500 and $756,900, respectively, compared to its carrying value, excluding the derivative liabilities and deferred financing costs, of $345,698, and $448,080, respectively. The Company estimates the fair value of its long-term debt using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered Level 2 inputs. At July 2, 2016 and December 31, 2015, the Company's short-term investments were comprised of time deposits with financial institutions that have maturities that exceed 90 days from the date of acquisition; however they all mature within one year from the respective balance sheet dates. The Company's short-term investments are accounted for as held-to-maturity debt instruments, at amortized cost, which approximates their fair value. The investments are funded with excess cash not expected to be needed for operations prior to maturity; therefore, the Company believes it has the intent and ability to hold the short-term investments until maturity. At each reporting date, the Company performs an evaluation to determine if any unrealized losses are other-than-temporary. No other-than-temporary impairments have been recognized on these securities, and there are no unrecognized holding gains or losses for these securities during the periods presented. There have been no transfers to or from the held-to-maturity classification. All decreases in the account balance are due to returns of principal at the securities' maturity dates. Interest on the securities is recognized as interest income when earned. At July 2, 2016 and December 31, 2015, the Company's cash and cash equivalents were comprised of demand deposits, time deposits with maturities of three months or less when purchased, and money market funds. The Company estimates the fair value of its cash, cash equivalents, and short-term investments using level 2 inputs. Based on the current interest rates for similar investments with comparable credit risk and time to maturity, the fair value of the Company's cash, cash equivalents, and held-to-maturity short-term investments approximate the carrying amounts reported in the consolidated condensed balance sheets. The Company's financial instruments also include accounts receivable, short-term notes payable, and accounts payable. The carrying amounts for these financial instruments reported in the consolidated condensed balance sheets approximate their fair values.

Effective Income tax Rate Description	The provision for income taxes consists of provisions for federal, state, and foreign income taxes. The effective tax rates for the periods ended July 2, 2016 and July 4, 2015 reflect the Company's expected tax rate on reported income from continuing operations before income tax and tax adjustments. The Company operates in a global environment with significant operations in various jurisdictions outside the United States. Accordingly, the consolidated income tax rate is a composite rate reflecting the Company's earnings and the applicable tax rates in the various jurisdictions where the Company operates.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	The amount of compensation cost related to stock-based payment transactions is measured based on the grant-date fair value of the equity instruments issued. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The Company determines compensation cost for restricted stock units ("RSUs"), phantom stock units, and restricted stock based on the grant-date fair value of the underlying common stock adjusted for expected dividends paid over the required vesting period for non-participating awards. Compensation cost is recognized over the period that an officer, employee, or non-employee director provides service in exchange for the award.

Segment Information [Abstract]
Segment Reporting, Policy [Policy Text Block]	Vishay operates, and its chief operating decision maker makes strategic and operating decisions with regards to assessing performance and allocating resources based on, five reporting segments: MOSFETs, Diodes, Optoelectronic Components, Resistors & Inductors, and Capacitors. The Company evaluates business segment performance on operating income, exclusive of certain items ("segment operating income"). Only dedicated, direct selling, general, and administrative expenses of the segments are included in the calculation of segment operating income. The Company's calculation of segment operating income excludes such selling, general, and administrative costs as global operations, sales and marketing, information systems, finance and administration groups, as well as restructuring and severance costs, goodwill and long-lived asset impairment charges, and other items. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company. These items represent reconciling items between segment operating income and consolidated operating income. Business segment assets are the owned or allocated assets used by each business.

Earnings Per Share [Abstract]
Discussion on convertible debt included in computation of earnings per share diluted	The Company's convertible debt instruments are only convertible for specified periods upon the occurrence of certain events. None of the conversion criteria were met for the periods presented. In periods that the debentures are not convertible, the certain conditions which could trigger conversion of the remaining debentures have been deemed to be non-substantive, and accordingly, the Company assumes the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive. At the direction of its Board of Directors, the Company intends, upon conversion, to repay the principal amounts of the convertible senior debentures, due 2040, due 2041, and due 2042, in cash and settle any additional amounts in shares of Vishay common stock. Accordingly, the debentures are included in the diluted earnings per share computation using the "treasury stock method" (similar to options and warrants) rather than the "if converted method" otherwise required for convertible debt. Under the "treasury stock method," Vishay calculates the number of shares issuable under the terms of the debentures based on the average market price of Vishay common stock during the period, and that number is included in the total diluted shares figure for the period. If the average market price is less than $13.25, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2040, if the average market price is less than $18.16, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2041, and if the average market price is less than $11.27, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2042.

Fair Value Measurements [Abstract]
Fair Value of Financial Instruments, Policy	The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company's own assumptions. An asset or liability's classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented.
