Basis of Presentation The condensed consolidated financial data at December 31, 2019 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission (“SEC”) on February 12, 2020 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2020. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current financial statement presentation. Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board issued Accounting Standards (“FASB”) Update (“ASU”) No. 2020-04 Reference Rate Reform (Topic 848) In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, which requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU No. 2016-13 effective January 1, 2020. The adoption of ASU No. 2016-13 did not have a mat erial impact on our consolidated financial statements and related disclosures.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 2 – Earnings per Share Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive. During the three and nine months ended September 30, 2020 and 2019 we paid no dividends on our Common Stock. The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS: Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 Earnings (numerator) Net income attributable to common stockholders $ 27,152 $ 38,060 $ 68,353 $ 106,060 Shares (denominator) Weighted average common shares outstanding (basic) 51,825 50,998 51,563 50,687 Dilutive effect of stock options and stock awards outstanding 904 871 1,049 1,012 Adjusted weighted average common shares outstanding (diluted) 52,729 51,869 52,612 51,699 Earnings per share attributable to common stockholders Basic $ 0.52 $ 0.75 $ 1.33 $ 2.09 Diluted $ 0.51 $ 0.73 $ 1.30 $ 2.05 Stock options and stock awards excluded from EPS calculation because the effect would be anti-dilutive - 3 3 107

Our undistributed foreign earnings continue to be indefinitely reinvested in foreign operations, with limited exceptions related to earnings of certain European and Asian subsidiaries. Any future distributions of foreign earnings will not be subject to additional U.S. income tax, but may be subject to non-U.S. withholding taxes. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of the Company’s unrecognized tax positions will significantly increase or decrease within the next 12 months. At this time, an estimate of the range of the reasonably possible outcomes cannot be made. In response to the outbreak of the novel strain of coronavirus (“COVID-19”) pandemic, the United States Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was enacted on March 27, 2020. We do not expect the CARES Act to have a material impact on our financial statements because we do not qualify for most of the relief provisions prescribed in the CARES Act. We will continue to assess the impacts of the CARES Act and any other legislation adopted by the United States government or other applicable governmental agencies in response to COVID-19 as additional guidance is published by the relevant authorities.

Debt Disclosure [Abstract]
Debt	NOTE 8 – Debt Our Asia subsidiaries maintain credit facilities with several financial institutions through our foreign entities worldwide totaling $155.7 million. Other than two Taiwanese credit facilities that are collateralized by assets, our foreign credit lines are unsecured, uncommitted, repayable on demand, terminable by the lender at any time and contain no restrictive covenants. Interest payments are due monthly on outstanding amounts under the credit lines. The unused and available credit under the various facilities as of September 30, 2020, was approximately $ 86.2 70.7 On May 29, 2020, the Company, Diodes Holding B.V. (the “Foreign Borrower” and, collectively with the Company, the “Borrowers”), and certain subsidiaries of the Company as guarantors, entered into a Second Amended and Restated Credit Agreement (the “Credit Agreement”) that amends and restates that certain Amended and Restated Credit Agreement dated as of October 26, 2016 (as amended, modified and/or supplemented from time to time prior to May 29, 2020, the “Existing Credit Agreement”). Certain capitalized terms used in this description of the Credit Agreement have the meanings given to them in the Credit Agreement. The Credit Agreement rebalances the Company’s existing senior credit facilities under the Existing Credit Agreement from (x) aggregate credit facilities of $500,000,000, consisting of (A) a $250,000,000 revolving senior credit facility, which included a $10,000,000 swing line sublimit, a $10,000,000 letter of credit sublimit, and a $20,000,000 alternative currency sublimit, and (B) a $250,000,000 term loan to (y) aggregate credit facilities of $670,000,000 consisting of (A) an acquisition draw term commitment of $340,000,000 (the “Acquisition Draw Term Commitment”), (B) an initial term commitment of $180,000,000 (the “Initial Term Commitment” and, together with the Acquisition Draw Term Commitment, the “Term Loan”) and (C) a $150,000,000 revolving senior credit facility (the “Revolver”), which includes a $ 20,000,000 uncommitted swing line sublimit, a $ 10,000,000 letter of credit sublimi t, and a $ 40,000,000 alternative currency sublimit. The Revolver and the Term Loan mature on May 29, 2023 (the “Maturity Date”). Both the term loan portion and the revolving portion of the Credit Agreement bear an interest rate at LIBOR or similar other indices plus a specified margin. The Company plans to use a portion of the proceeds available under the Revolver and the Term Loan (i) to finance the Company’s previously announced acquisition of Lite-On Semiconductor Corporation, (ii) to refinance certain existing indebtedness of the Borrowers and their subsidiaries under the Existing Credit Agreement and (iii) for working capital, capital expenditures, and other lawful corporate purposes, including, without limitation, financing permitted acquisitions. The Credit Agreement contains certain financial and non-financial covenants, including, but not limited to, a maximum Consolidated Leverage Ratio, a minimum Consolidated Fixed Charge Coverage Ratio, and restrictions on liens, indebtedness, investments, fundamental changes, dispositions, and restricted payments (including dividends and share repurchases). These covenants are generally similar to the corresponding covenants in the Existing Credit Agreement, except that certain amounts permitted as exceptions to negative covenants restricting liens, indebtedness, investments, dispositions and restricted payments have been revised, and additional exceptions to certain negative covenants have been added, including increased capacity for certain intercompany Indebtedness and Investment (including existing Lite-On Indebtedness), and the right to enter into certain securitization transactions and receivables facilities, subject to limitations set forth in the Credit Agreement. Furthermore, under the Credit Agreement, restricted payments, including dividends and share repurchases, are permitted in certain circumstances, including while the pro forma Consolidated Leverage Ratio is, both before and after giving effect to any such restricted payment, at least 0.25 to 1.00 less than the maximum permitted under the Credit Agreement. In addition to the liquidity provided by the Credit Agreement, our 51% owned subsidiary, ERIS Technology Corporation (“ERIS”), borrowed $13.7 million through a short-term loan and $29.4 million on a long-term basis from local Taiwan banks.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9 – Commitments and Contingencies Purchase commitments – As of September 30, 2020, we had approximately $19.8 million in non-cancelable purchase contracts related to capital expenditures, primarily related to our manufacturing facilities in Asia. As of September 30, 2020, we also had a commitment to purchase approximately $20.3 million of wafers to be used in our manufacturing process. These wafer purchases will occur during 2020. Defined Benefit Plan - We have a contributory defined benefit plan that covers certain employees in the United Kingdom. As of September 30, 2020, the unfunded liability for this defined benefit plan was approximately $30.7 million. An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $34.7 million based on a GBP: USD exchange rate of 1.3:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.6 million based on a GBP: USD exchange rate of 1.3:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million in annual installments effective April 1, 2020 to cover expenses. Contingencies – From time to time, we are involved in various legal proceedings that arise in the normal course of business. While we intend to defend any lawsuit vigorously, we presently believe that the ultimate outcome of any pending legal proceeding will not have any material adverse effect on our consolidated financial position, cash flows or operating results. However, litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, which could impact our business and operating results for the period in which the ruling occurs or future periods. Based on information available, we evaluate the likelihood of potential outcomes of all pending disputes. We record an appropriate liability when the amount of any liability associated with a pending dispute is deemed probable and reasonably estimable. In addition, we do not accrue for estimated legal fees and other directly related costs as they are expensed as incurred. The Company is not currently a party to any pending litigation that the Company considers material.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 10 – Derivative Financial Instruments We use derivative instruments to manage risks related to foreign currencies, interest rates and the net investment risk in our foreign subsidiaries. Our objectives for holding derivatives include reducing, eliminating, and efficiently managing the economic impact of these exposures as effectively as possible. Our derivative programs include strategies that both qualify and do not qualify for hedge accounting treatment. Hedges of Foreign Currency Risk - We are exposed to fluctuations in various foreign currencies against our different functional currencies. We use foreign currency forward agreements to manage this exposure. At September 30, 2020, and December 31, 2019, we had $124.7 million and $105.9 million, respectively, outstanding foreign currency forward contracts that are intended to preserve the economic value of foreign currency denominated monetary assets and liabilities; these instruments are not designated for hedge accounting treatment in accordance with ASC No. 815. The fair value of these instruments approximates zero. Hedges of Interest Rate and Net Investment Risk - The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The second tranche, currently recorded in other current liabilities, as shown in the table below, and currently valued at $ 8.5 million will increase the Company’ s ownership to at least 51 % of Savitech. The second tranche will be paid on June 30, 2021, provided Savitech achieves previously agreed-to revenue levels. If revenue levels are not achieved the Company will pay less than the maximum $ 8.6 million, but regardless of the amount paid for the second tranche, the Company will still acquire at least 51 % of Savitech. The Company recorded the purchase of Savitech as a business acquisition and will consolidate Savitech into its operations, based on the voting model, with a non-controlling interest related to the interest the Company does not own in Savitech. The Company made its investment in Savitech in order to increase the Company’s integrated circuit business.

Total consideration paid by the Company was $33.2 million and was funded by advances under the revolving portion of our long-term credit facility. The facility and assets were wholly acquired, and there is no remaining minority interest. The goodwill will not be tax deductible. The Company also incurred acquisition costs of approximately $0.6 million that were recognized in selling, general and administrative expense.

Basis of Presentation	Basis of Presentation The condensed consolidated financial data at December 31, 2019 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission (“SEC”) on February 12, 2020 (“Form 10-K”). The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, operating results and cash flows in conformity with GAAP for complete financial statements. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in our Form 10-K. All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the operating results for the period presented have been included in the interim period. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2020. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. As permitted under GAAP, interim accounting for certain expenses, including income taxes, are based on full year forecasts. For interim financial reporting purposes, income taxes are recorded based upon estimated annual effective income tax rates taking into consideration discrete items occurring in a quarter. Dollar amounts and share amounts are presented in thousands, except per share amounts, unless otherwise noted. Certain prior year’s balances may have been reclassified to conform to the current financial statement presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board issued Accounting Standards (“FASB”) Update (“ASU”) No. 2020-04 Reference Rate Reform (Topic 848) In June 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-13, which requires measurement and recognition of expected credit losses for financial assets held. We adopted ASU No. 2016-13 effective January 1, 2020. The adoption of ASU No. 2016-13 did not have a mat erial impact on our consolidated financial statements and related disclosures.

Defined benefit plan, estimated future employer contributions in current fiscal year, description	We have a contributory defined benefit plan that covers certain employees in the United Kingdom.  As of September 30, 2020, the unfunded liability for this defined benefit plan was approximately $30.7 million.  An actuarial valuation was performed as of March 31, 2019, resulting in a deficit of approximately GBP 26.7 million (approximately $34.7 million based on a GBP: USD exchange rate of 1.3:1). As a result of this valuation we have agreed to a revised schedule of contributions of GBP 2.0 million (approximately $2.6 million based on a GBP: USD exchange rate of 1.3:1) to be paid in annual installments with effect from April 1, 2020 to address the deficit revealed by the valuation (with the first payment made by March 31, 2021, and payments to be made by December 31 each year thereafter). These contributions, together with the assumed asset outperformance, are expected to eliminate the deficit by December 31, 2028. Further, we will pay GBP 0.2 million in annual installments effective April 1, 2020 to cover expenses.

Objectives for using derivative instruments	The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives, the Company primarily uses interest rate swaps, including interest rate collars, as part of its interest rate risk management strategy.  Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.
