STMicroelectronics has begun volume production of e-mode PowerGaN HEMT (high-electron-mobility transistor) devices that simplify the design of high-efficiency power-conversion systems. The STPOWER GaN transistors raise performance in applications such as wall adapters, chargers, lighting systems, industrial power supplies, renewable energy applications, and in automotive electrification. The first two products in the family, the SGT120R65AL and SGT65R65AL, are industrial-qualified 650V normally-off G-HEMT in a…
