1200V / 180A Full SiC Power Module with Integrated
SiC Trench MOSFET
BSM180D12P3C007
New full SiC power module with built-in
SiC trench MOSFET reduces ON resistance
and improves switching performance
Product Outline
SiC devices are attracting attention due to their superior performance and characteristics compared with silicon as
a semiconductor material.
ROHM’s new SiC MOSFET, which utilizes a trench structure that reduces ON resistance by 50% and input
capacitance by 35% compared with existing planar-type SiC MOSFETs, has been adopted in ROHM’s
1200V/180A full SiC power module.
