Acquisition and Divestiture Activities [Abstract]
Acquisition and Divestiture Activities	Note 2 - Acquisition and Divestiture 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. Year ended December 31, 2023 Neptune 6 Limited On November 8, 2023, Vishay and Nexperia BV announced that they have entered into an agreement whereby Vishay will acquire Nexperia’s wafer fabrication facility and operations located in Newport, South Wales, U.K. for approximately $177,000 in cash, subject to customary post-closing adjustments. On November 8, 2023, Vishay remitted $8,750 to an escrow account as a deposit for the acquisition. Such amount is included within "Purchase of and deposits for businesses, net of cash acquired" on the consolidated statement of cash flows. To effect the transaction, Vishay will acquire 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. The closing of the transaction is subject to U.K. government review and customary closing conditions, and is expected to occur in the first quarter of 2024. Centerline Technologies, LLC On June 30, 2023, the Company acquired substantially all of the assets of Centerline Technologies, LLC ("Centerline"), a Massachusetts-based, privately held manufacturer of ceramic components used in many custom parts manufactured by certain of Vishay's Resistors businesses, for $5,003. Based on an estimate of fair values, the Company allocated $1,500 of the purchase price to definite-lived intangible assets. 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 $2,213 related to this acquisition. The acquired business will be vertically integrated into the Company's Resistors segment, and 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 30, 2023. Year ended December 31, 2022 On October 28, 2022, the Company acquired all of the outstanding equity interests of MaxPower Semiconductor, Inc., ("MaxPower"), a San Jose, California-based fabless power semiconductor provider dedicated to delivering innovative and cost-effective technologies that optimize power management solutions. The acquisition of MaxPower will enhance Vishay's current and future silicon carbide ("SiC") offerings for fast-growing markets such as electric vehicles. 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. The purchase price for U.S. GAAP purposes includes the fair value, as of the acquisition date, of certain future contingent payments to non-employee equity holders of MaxPower. The estimated fair value of this contingent consideration as of the acquisition date was $6,851. The contingent consideration liability is included in other accrued expenses and other liabilities in the accompanying balance sheet and is remeasured each reporting period, with changes reported as "Selling, general, and administrative expenses" on the consolidated statements of operations. A portion of contingent payments to be made to employee equity holders are deemed compensatory in nature. Such payments made to employee equity holders will be recognized as expense in future periods, and thus are not included in the U.S. GAAP purchase price. One of the contingencies was resolved in the fourth quarter of 2023, which resulted in no additional payments to the former employees and stockholders of MaxPower. Significant developments occurred in another of the contingencies in January 2024. The Company's estimate of the maximum possible contingent payments is $17,500. See Note 18 for further discussion on the fair value measurement of the contingent consideration liability. Based on an estimate of their fair values, the Company allocated $18,600 of the purchase price to definite-lived intangible assets. 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 $34,246 related to this acquisition. The results and operation of this acquisition have been included in the MOSFETs segment since October 28, 2022. The goodwill related to this acquisition is included in the MOSFETs reporting unit for goodwill impairment testing. Year ended December 31, 2021 On December 31, 2021, the Company acquired substantially all of the U.S. assets of Barry Industries, a Massachusetts-based, privately-held manufacturer of resistive components for $20,847. Based on an estimate of their fair values, the Company allocated $9,600 of the purchase price to definite-lived intangible assets. 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 $7,813 related to this acquisition. The results and operations of this acquisition have been included in the Resistors segment since December 31, 2021. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing.
