Provides simultaneous high voltageresistance, low ON resistance, high-speed switching, and fast recovery

ROHM’s 1200V SiC MOSFETs provide low loss during high frequency operation. In particular, switching loss is reduced by 90% compared with Si IGBTs, decreasing both chip size and costs. In addition, improved processes related to crystal defects and optimized device structure ensure high reliability. ROHM also offers the industry’s first* SiC MOSFET that integrates an SiC-SBD in the same package for low VF, making it ideal for inverter applications and more.

1200V Voltage Resistance SiC MOSFETs

Low switching loss contributes to improved energy savings and increased miniaturizationROHM SiC MOSFETs achieve high-speed switching and high voltage resistance not possible with their silicon counterparts.As a result, turn OFF loss is reduced by over 90%, while high-speed diode recovery characteristics reduce loss by 73% over silicon IGBTs during operation for minimal power consumption.

VDS-ID characteristics comparisonInnovations such as gate oxidizing conditions enable an ON resistance per-unit-area 29% lower than conventional products, resulting in the lowest ON resistance at 1200V in the TO-247 MOSFET class*. In addition, low ON resistance is maintained even at high temperatures, and no voltage rise ensures low loss even during light loads.
