# Transphorm

> Transphorm was a GaN (gallium nitride) power-semiconductor company based in Goleta, California, known for its GaN-on-Si cascode FET technology used in power supplies, adapters, motor drives, solar inverters, and EV charging. It was acquired by Renesas Electronics in June 2024, and transphormusa.com now redirects to the Renesas GaN power-discretes product line. Transphorm publishes no public web API surface; its former developer resources (datasheets, application notes, design tools) live on renesas.com.
