Acquisition 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. These acquisition targets include businesses 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. It also includes certain businesses that possess technologies which the Company expects to further develop and commercialize. Newport wafer fab On March 5, 2024, the Company acquired Nexperia’s wafer fabrication facility and operations located in Newport, South Wales, U.K. for $177,457 in cash, net of cash acquired. The transaction included contingent payments of up to $15,000, held in escrow pending receipt of an export license. The wafer fabrication facility is located on 28 acres and is an automotive-certified, 200mm semiconductor wafer fab with capacity to produce more than 30,000 wafers per month. See Note 13 for further discussion on the fair value measurement of the contingent consideration liability. The transaction was funded by Vishay with cash on-hand. To effect the transaction, Vishay acquired a 100% interest in the legal entity Neptune 6 Limited, and its wholly-owned operating subsidiary, Nexperia Newport Limited, which owns and operates the Newport facility. Neptune 6 Limited was renamed "Vishay UK Holdings Limited," and Nexperia Newport Limited was renamed "Vishay Newport Limited." Based on an estimate of fair values, the Company allocated the purchase price of the acquisition as follows: Net working deficit (excluding cash and cash equivalents) $ (339 ) Property and equipment 153,597 Customer relationships 4,000 Other, net 1,315 Deferred taxes, net (18,908 ) Total identified assets and liabilities 139,665 Purchase price, net of cash acquired 177,457 Goodwill $ 37,792 The acquired assets and liabilities are included in the MOSFETs segment. The weighted average useful lives for customer relationships is 3 years. The goodwill associated with this transaction is not deductible for income tax purposes. The preliminary purchase price allocation is pending finalization of appraisals for property and equipment and intangible assets. There can be no assurance that the estimated amounts recorded represent the final purchase price allocation. The Company recognized $2,984 of acquisition costs classified as a component of selling, general, and administrative expenses. These costs were recognized in the third and fourth fiscal quarters of 2023 and first fiscal quarter of 2024. The results and operations of this acquisition have been included in the MOSFETs segment since March 5, 2024. The inclusion of this acquisition did not have material impact on the MOSFETs segment's or the Company's consolidated results. Ametherm, Inc. On June 5, 2024, the Company acquired all of the outstanding equity interests of Ametherm, Inc., a Carson City, Nevada-based manufacturer of inrush current limiting solutions and power thermistors, for $31,478 in cash, net of cash acquired. Based on a preliminary estimate of fair values, the Company allocated $17,000 of the purchase price to definite-lived intangible assets. After allocating the purchase price to assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $11,710 related to this acquisition. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. The results and operations of this acquisition have been included in the Resistors segment since June 5, 2024. MaxPower Semiconductor, Inc. In October 2022, the Company acquired all of the outstanding equity interests of MaxPower Semiconductor, Inc., ("MaxPower"). The Company paid cash of $50,000, net of cash acquired, at closing. The transaction also included possible contingent payments of up to $57,500, which would be payable upon the achievement of certain technology milestones, upon favorable resolution of certain technology licensing matters with a third party, and upon the disposition of MaxPower's investment in an equity affiliate. As of June 29, 2024, the contingent payments upon favorable resolution of certain technology licensing matters with a third party and upon the disposition of MaxPower's investment in an equity affiliate have been resolved. Additionally, $2,500 has been paid upon the achievement of the first technology milestone. The Company's estimate of the maximum possible contingent payments remaining is now $15,000.

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 June 29, 2024 and July 1, 2023 reflect the Company’s expected tax rate on reported income 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. In December 2021, the Organization for Economic Co-operation and Development (“OECD”) issued model rules for a new global minimum tax (“Pillar Two”). Various jurisdictions around the world have passed, or are in the process of passing, legislation to enact Pillar Two and certain Pillar Two rules take effect in 2024 and 2025 in those jurisdictions. The United States has not adopted Pillar Two. The Company is continuing to monitor the impacts of Pillar Two on its operations and does not anticipate a material increase in income tax expense associated with jurisdictions that have implemented an income inclusion rule. The Company is continuing to monitor and assess the impacts of Pillar Two rules set to take effect in 2025, such as the under-taxed profits rule. The Company repatriated $120,000 of accumulated earnings to the United States in the second fiscal quarter of 2024 and paid withholding taxes, in Israel, of $15,000. The withholding tax expense for the repatriation was recorded in prior years. During the six fiscal months ended June 29, 2024, the liabilities for unrecognized tax benefits decreased $729 on a net basis, primarily due to statute expirations, partially offset by accruals for the current period.

Fair Value Measurements [Abstract]
Fair Value Measurements	Note 13 – Fair Value Measurements 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 June 29, 2024 Assets: Assets held in rabbi trusts $ 51,149 $ 23,289 $ 27,860 $ - Available for sale securities $ 3,996 3,996 - - $ 55,145 $ 27,285 $ 27,860 $ - Liability: Acquisitions contingent consideration $ 15,664 $ - $ - $ 15,664 December 31, 2023 Assets: Assets held in rabbi trusts $ 50,378 $ 24,343 $ 26,035 $ - Available for sale securities $ 4,115 4,115 - - $ 54,493 $ 28,458 $ 26,035 $ - Liability: MaxPower acquisition contingent consideration $ 938 $ - $ - $ 938 There have been no changes in the classification of any financial instruments within the fair value hierarchy in the periods presented. 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 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 period. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy. The Company may be required to make certain contingent payments to non-employee equity holders of MaxPower pursuant to the acquisition agreement, which will be payable upon the achievement of certain technology milestones. The Company may be required to make certain contingent payments upon the receipt of an export license pursuant to the Newport wafer fab acquisition agreement. The fair value of these contingent consideration payments is determined by estimating the net present value of the expected cash flows based on the probability of expected payments. The fair value measurement of the contingent consideration is considered a Level 3 measurement within the fair value hierarchy. The fair value of the long-term debt, excluding the derivative liabilities and deferred financing costs, at June 29, 2024 and December 31, 2023 is approximately $809,400 and $836,200, respectively, compared to its carrying value, excluding the deferred financing costs, of $845,102. 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 June 29, 2024 and December 31, 2023, 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 June 29, 2024 and December 31, 2023, 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 and accounts payable. The carrying amounts for these financial instruments reported in the consolidated condensed balance sheets approximate their fair values.
