ROHM’s fourth-generation SiC MOSFETs have been adopted in Toyota’s new bZ5 BEV, and the impact on the Chinese EV market is attracting attention.
🟦 ROHM’s SiC power module used in Toyota bZ5
ROHM’s high-performance fourth-generation silicon carbide (SiC) MOSFETs have been selected for the traction inverter of Toyota’s new bZ5 electric vehicle. This adoption contributes to the improvement of the cruising range and performance of EVs.
- The power modules used will be mass-produced and shipped from HAIMOSIC (Shanghai Hai Semiconductor Co., Ltd.), a joint venture established by ROHM and China’s Zhenghai Group
- SiC MOSFETs reduce power loss, and the bZ5 has a range of up to 630 km (CLTC mode)
- The bZ5 is a crossover BEV for the Chinese market jointly developed by BTET, a joint venture between Toyota and BYD.
🟦 Market direction indicated by the collaboration between Toyota and ROHM
In order to expand the EV market and realize a decarbonized society, the demand for SiC power semiconductors is increasing worldwide. China, in particular, is the world’s largest EV market, and collaboration with local partners is key to strengthening competitiveness.
ROHM also supplies SiC to automakers in China, and is working to penetrate the market through local production. In addition, ROHM is looking to launch fifth-generation SiC devices in 2025, as well as sixth- and seventh-generation SiC devices, strengthening its preparations for global electrification demand.
🟦 Summary
The adoption of ROHM’s SiC power modules in Toyota’s bZ5 is a major step forward in increasing its presence in the Chinese EV market.
ROHM’s 20% stake in HAIMOSIC is an attempt to secure the speed and competitiveness of its business through local production and supply while increasing its presence in the Chinese market.
