Nature Of Operations Basis Of Presentation And Recently Issued Accounting Pronouncements [Abstract]
Nature of Operations	Nature of Operations Diodes Incorporated, together with its subsidiaries (collectively, the “Company,” “we” or “our”), is a leading global manufacturer and supplier of high-quality, application specific standard products within the broad discrete, logic and analog semiconductor markets, serving the consumer electronics, computing, communications, industrial and automotive markets throughout Asia, North America and Europe.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S.”) (“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 U.S. GAAP for complete financial statements. These consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the our Annual Report on Form 10-K for the year ended December 31, 2014. 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 six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for other interim periods or the year ending December 31, 2015. The consolidated condensed financial data at December 31, 2014 is derived from audited financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed on March 2, 2015. The preparation of financial statements in conformity with U.S. 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 U.S. 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. Certain prior year’s balances have been reclassified to conform to the current financial statement presentation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 was originally effective for us in the first quarter of 2017, but in July 2015 the FASB approved a proposal to defer the effective date to the first quarter of 2018. Under this proposal, early adoption is permitted as of the original effective time period of first quarter of 2017 and requires either a retrospective or a modified retrospective approach to adoption. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures.
