We are Hitachi Energy Semiconductors. Inspire the next era of sustainable energy

Our power electronics journey began over 100 years ago in Switzerland. Today, we offer one of the most diverse semiconductor portfolios - thyristors, diodes, GTOs, IGCTs, IGBTs, and MOSFETs -produced in Lenzburg and Prague. Using silicon and silicon carbide, our research drives innovation in next-gen power devices. Our technology powers HVDC systems, high-speed trains, metros, industrial drives, and the future of e-mobility.
