Transphorm, Inc. is an American semiconductor company focused on producing transistors made from gallium nitride (GaN) for use in switched-mode power supplies.
[16][17] In August 2021, Transphorm acquired 100% interest in the AFSW wafer-fab facility from GaNovation, a manufacturer for high voltage GaNs.
[18] In March 2023, Transphorm released the first gallium nitride (GaN) System-in-Package (SiP) together with Weltrend Semiconductor Inc..
The Weltrend SiP will be showcased by Transphorm at the 2023 Applied Power Electronics Conference (APEC).
[19][20] Together with Yaskawa Electric, Transphorm has developed a new patented technology for GaN power transistors with a short circuit withstand time (SCWT) of 5 microseconds in August 2023.
