What is Renesas RTP100 100 V enhancement-mode GaN FET family?

Power electronics is the field of controlling and converting electricity, for example inside a switched-mode power supply. Its core part is the power semiconductor device, which works as a switch or rectifier and is usually either fully on or fully off, so these devices are designed for that on/off use. The Renesas RTP100 family is a set of 100 V transistors made from gallium nitride (GaN) rather than silicon. They are enhancement-mode, meaning normally off, and, the maker says, have silicon-compatible footprints that simplify migration from silicon-based designs. The maker describes them as aimed at efficiency-critical, high power density uses such as AI data centers, humanoid robotics and industrial motor drives, and Renesas announced the family on October 6, 2026.
