Rohm extends lineup of Automotive-grade SiC MOSFETs
Chipmaker Rohm has added ten new automotive-grade SiC MOSFETs to its product portfolio. After the introduction of the SCT3xxxxxHR series, Rohm claims to offer the industry's largest lineup of AEC-Q101 qualified SiC MOSFETs that provide the high reliability necessary for automotive on board chargers and DC/DC converters.


In recent years an increasing number of automotive makers are offering electric vehicles in response to growing environmental awareness and rising fuel costs. However, although EVs are becoming more widespread, their relatively short driving range remains problematic. To improve driving distance, batteries are trending towards larger battery capacities with shorter charging times. This, in turn, demands high power and efficiency on board chargers such as 11kW and 22kW, leading to increased adoption of SiC MOSFETs. In addition, higher voltage batteries (800V) require power devices featuring low loss and higher withstand voltages.

To meet these needs, Rohm added 10 new models to its lineup of AEC-Q101 qualified MOSFETs that utilizes a trench gate structure. The result is the industry’s largest portfolio, available in both 650V and 1200V variants. And going forward, Rohm will strive to further improve quality and strengthen its lineup to increase device performance, reduce power consumption, and achieve greater miniaturization.
