Westcode Semiconductors

Since the early part of the 20th Century, the Company has been at the forefront of power semiconductor design. In the early 1920's we introduced the worlds first commercial rectifier and have continued to push ahead bringing ever more advanced power management solutions to market. In almost every corner of the globe IXYS UK products are hard at work keeping industry moving forward.

Supporting a truly worldwide and incredibly diverse market place, IXYS UK Westcode Ltd has evolved into one of the worlds leading manufacturers of very high power semiconductors.

A sincere commitment to our customers and a passion for technical excellence will ensure that our future is every bit as bright as our past.

Our History in Brief

With origins in the mid 1920’s, Westcode Semiconductors began life in London as part of the Westinghouse Brake & Signal Company making copper oxide based semiconductors. Manufacturing started at the Chippenham site in the 1930’s and during the next 30 years the company developed products based on selenium and germanium before silicon power devices were introduced in 1957; technology which is still used in products today. Clean rooms and manufacturing were consolidated into the present purpose built facilities in 1998.

Since its origins as part of the Westinghouse brake and signal company, Westcode Semiconductors Ltd had several owners including Hawker Siddeley and BTR, before its acquisition by the IXYS Corporation in December 2001

In 2012, to reflect a more integrated global presence, Westcode Semiconductors Ltd changed its name to IXYS UK Westcode Ltd., and continues to supply high technology components for a wide range of applications such as; welding, AC and DC drives, rectifier supplies, uninterruptible power supplies, motor soft starts, transportation, induction heating, power conditioning, high energy physics and many other industrial uses.

IXYS has successfully expanded its "high power" centric strategy to become a more diversified supplier of medium to high power, Mixed-Signal IC, Optoelectronic and RF semiconductors. The IXYS group has manufacturing plants in Germany, USA and the UK. With a very well established worldwide sales network, our products fit neatly into the IXYS product portfolio, sitting very much at the high end of the power semiconductor market.
