The power module equipped with ROHM Co., Ltd.’s 4th generation SiC MOSFET bare chip has been
adopted in the traction inverter of Toyota Motor Corporation’s new crossover BEV “bZ5” for the Chinese market.The “bZ5” is a crossover-type BEV jointly developed by Toyota, BYD TOYOTA EV TECHNOLOGY
Co., Ltd. (hereinafter “BTET”), FAW Toyota Motor Co., Ltd. (hereinafter “FAW Toyota”), etc., and was
launched by FAW Toyota in June 2025.The power module adopted this time has started mass production shipments from HAIMOSIC
(SHANGHAI) Co., Ltd., a joint venture between ROHM and Zhenghai Group. ROHM’s power solutions centered on SiC MOSFETs contribute to the extended range and enhanced performance of the new
BEV.ROHM aims to complete the construction of the production line for the next-generation 5th generation SiC MOSFET by 2025, and is also accelerating the market introduction plans for the 6th and 7th generations, focusing on the development of SiC power devices. ROHM will continue to work on improving device performance and production efficiency, and strengthen the system to provide SiC in
various forms such as bare chips, discrete components, and modules, promoting the spread of SiC
and contributing to the creation of a sustainable mobility society.Original – ROHM
