Transphorm was founded in February 2007 in Delaware.[3][4] It is headquartered in Goleta, California, close to the University of California at Santa Barbara (UCSB) from which the company is an offshoot and where the co-founder and CTO, Umesh Mishra, is a professor.[5][6][7]
In 2011, Google Ventures invested $20 million into Transphorm. The money is to assist the companies development of power conversion technologies.[8][9] They also received capital from Kleiner Perkins and others amounting to $18 million.[9]
In September 2012, Transphorm released the TPH2006PS which was the first JEDEC qualified 600V HEMT in the industry.[10][11]
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.[12][13][14]
In 2015, they received a $70 million investment which was led by the global investment firm KKR.[15]
Transphorm went public by reversing merging with a special-purpose acquisition company, Peninsula Acquisition Corporation, in February 2020.[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.[21][22]
In January 2024, Renesas Electronics agreed to acquire Transphorm for $339 million.[23] On June 20, 2024, it was announced that Renesas had completed the purchase of the company.
