Celebrating its 60th anniversary in 2017, Dynex has a long and proud history of manufacturing and providing semiconductor products to the world.
British Thomson-Houston Company Limited ("BTH")A power semiconductor business was opened in Lincoln by BTH in 1956 manufacturing some of the first silicon-based semiconductor components in the world.
AEI Semiconductors LtdBTH was acquired by Associated Electrical Industries Ltd (AEI). The Lincoln subsidiary business of AEI was called, AEI Semiconductor Ltd. AEI was subsequently acquired by the General Electronic Company ("GEC").
Marconi Electronic Devices LtdThe power semiconductor business AEI Semiconductor Ltd was merged with GEC's other electronic component manufacturing businesses and named Marconi Electronic Devices Ltd.
GEC Plessey SemiconductorsAs a result of GEC acquiring the Plessey Company, the business operated under the name of GEC Plessey Semiconductors.
Mitel Semiconductor LtdMitel acquired the GEC Plessey Semiconductor Group. The combined semiconductor business ranks Mitel among the top ten networking companies in the world and provides the ability to produce bipolar, Complementary Metal Oxide Semiconductor (CMOS) and optoelectronic components.
Dynex Power Inc.In 2000, Dynex Power Inc, a small, publicly quoted Canadian company, formed Dynex Semiconductor Ltd to purchase the Lincoln Business Unit assets of Mitel Semiconductor Ltd.
Dynex Semiconductor Ltd.Following the acquisition, Dynex Power’s operations in Canada were closed down and all operations of Dynex Power Inc were carried out in Lincoln as part of Dynex Semiconductor Ltd.
Zhuzhou CSR Times Electric Co. LtdIn 2008, Zhuzhou CSR Times Electric Co. Ltd, a company based in the Hunan Province of The People’s Republic of China bought 75% of the share capital of Dynex Power Inc. CSR would later rebrand as CRRC Times Electric and is quoted in Hong Kong but is majority owned by the CRRC Group also based in Hunan Province in The People’s Republic of China.
The Dynex VisionDynex, in partnership with CRRC Times Electric, will be a leading international, top three high power semiconductor business.
Dynex now provides our high power semiconductor devices and assemblies into over 60 countries around the world.
