Dynex Semi

For more than 70 years, Dynex Semiconductor has been designing and manufacturing high-power semiconductor solutions from its headquarters in Lincoln, England.

From renewable energy farms and HVDC transmission networks to rail transportation, industrial power systems, and fusion energy research, Dynex technologies help customers convert, control, and deliver electrical power efficiently and reliably around the world.

As one of the few vertically integrated power semiconductor manufacturers in Europe, Dynex controls the entire production process from device design and wafer fabrication through to assembly, testing, and application support. This unique capability enables close engineering collaboration, exceptional quality control, and the flexibility to develop solutions for some of the world's most demanding applications.

Our portfolio includes high-power thyristors, diodes, GTOs, IGBT modules, silicon carbide (SiC) power modules, GaN modules, power assemblies, and custom-engineered solutions. These technologies support critical infrastructure where reliability, performance, and long operational lifetimes are essential.

As part of the CRRC Group, Dynex combines the heritage and expertise of British semiconductor engineering with access to global research, manufacturing resources, and international markets.

Today, Dynex products are helping to power the transition to a cleaner, more connected, and more electrified future, supporting renewable energy generation, strengthening power grids, enabling efficient transportation, and advancing scientific discovery.
