Dynex Semiconductor based in Lincoln, England, United Kingdom is a global supplier of products and services specialising in the field of power semiconductor devices and silicon on sapphire integrated circuit products.
The power products they manufacture include IGBTs, various types of thyristor and GTOs.
Since then it acquired the power semiconductor interests, technologies and products from some major names such as GEC, SGS-Thomson, Alstom and Marconi Electronic Devices (MEDL).
In 2008, 75% of Dynex Power shares were acquired by Chinese manufacturer Zhuzhou CSR Times Electric Co., Ltd., a subsidiary of CSR Corporation Limited.
