ROHM announces the launch of 10 new automotive grade SiC MOSFETs, the SCT3xxxxxHR series, which enables ROHM to offer the industry’s largest AEC-Q101 compliant SiC MOSFET product line, providing high reliability for automotive onboard chargers and DC/DC converters.

In recent years, more and more car manufacturers have introduced electric vehicles. However, the problem of relatively short mileage of electric vehicles has become the biggest challenge for electric vehicle manufacturers. In order to improve the driving distance, a larger battery capacity and a shorter charging time are required. This requires high power and high efficiency onboard chargers such as 11kW and 22kW, which increases the adoption rate of SiC MOSFETs. In addition, higher voltage batteries (800V) require power devices with low loss and higher withstand voltage.

To meet these needs, ROHM has added 10 new models to its AEC-Q101 compliant MOSFET family with trench gate structures. In the future, ROHM will strive to further improve quality and strengthen its product lineup to improve equipment performance, reduce power consumption and achieve greater miniaturization.
