IXYS UK Westcode is one the of the UK’s leading semiconductor manufacturers. Formerly known as Westcode, they launched the world’s first commercial rectifier in the early 1920’s. Westcode was acquired by IXYS Corporation in 2002, and shortly after changed its name to IXYS UK Westcode. Today, they manufacture high power thyristor capsules (GTO, fast & standard recovery), diode capsules (fast & standard recovery) and IGBT capsules.

As IXYS UK Westcode’s Official UK Distributor, we stock Europe’s largest range of IXYS UK’s semiconductors, fuses and capacitors. The company provide a large range fuses offering fast-acting, ultra rapid protection against device rupture and external short circuits. IXYS UK’s range of fuses feature proven advanced technology to international standards and are UL recognised. IXYS UK Westcode offer a range of power electronic capacitors to suit almost any application from filtering and smoothing DC voltages to GTO/IGBT snubber circuits and medium frequency applications.

One of the industries leading power semiconductor manufacturers, IXYS UK Westcode supplies high technology components to a wide range of applications, including: welding, AC and DC drives, rectifier supplies, uninterruptible power supplies, motor soft starts, transportation, induction heating and power conditioning.
