In 2011, Google Ventures invested $20 million into Transphorm. The money is to assist the companies development of power conversion technologies.[5][6] They also received capital from Kleiner Perkins and others amounting to $18 million.[6]

In September 2012, Transphorm relased the TPH2006PS which was the first JEDEC qualified 600V HEMT in the industry.[7][8]

In November 2013, Transphorm teamed up with Fujitsu Semiconductor to integrate their GaN power devices into power supply businesses with Fujitsu as well as Fujitsu Semiconductor only taking minority equity positions.[9][10][11]

In 2015, they received a $70 million investment which was led by the global investment firm KKR.[12]

In August 2021, Transphorm acquired 100% interest in the AFSW wafer-fab facility from GaNovation, a manufacturer for high voltage GaNs.[13]

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).[14][15]

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.[16][17]
