High Power Semiconductors

Dynex manufacture high performing and reliable devices that are currently in service in over 60 different countries. Our high power IGBT modules are lead-free and encompass Power Cycling with the latest generation IGBT die. Dynex Bipolar devises are also lead-free amd offer a reliable and efficient transfer of energy for a range of applications.

Power Assemblies

Providing support for customers that require more than the basic semiconductor. Specialising in the design and manufacture of assemblies such as rectifiers and converters, Dynex has an established supply chain for all components of power assemblies, resistors and capacitors for snubber networks and control circuits.

Dynex Semiconductor is a subsidiary company of Zhuzhou CRRC Times Electric Corporation Ltd, with a UK based in-house manufacturing plant and the ability to outsource high quantities to facilities in China to maintain competitive lead times.
