Hitachi Energy’s history in Switzerland began over 100 years ago with the development and production of mercury arc rectifiers. Today, Hitachi Energy has one of the most diverse portfolios in power semiconductors. We offer IGBTs, thyristors, diodes, GTOs, IGCTs and MOSFETs of the latest technology and highest quality standards. Production takes place in Switzerland and the Czech Republic. Several research teams are constantly pushing the boundaries of what is possible in semiconductor technology. Hitachi Energy products are at the heart of many applications in railroads, electromobility, hoists, pumps and fans to name just a few.
