Silicon carbide MOSFET SCT4018KTW

SiCfor automotive applicationshigh-voltage resistance

Overview
This product is a SiC MOSFET in the TSC3PAK package. By adopting a top-side heat dissipation structure that places the heat dissipation surface on the top of the package, the product enables automated mounting while achieving heat dissipation performance comparable to conventional through-hole packages. The package incorporates ROHM’s proprietary groove structure to secure a creepage distance of 6.66 mm, allowing it to accommodate an AC peak voltage of 1200 V in a Pollution Degree 2 environment while maintaining compatibility with widely adopted market products. The product incorporates ROHM’s 4th Generation SiC MOSFET, achieving low ON resistance and high-speed switching characteristics, which reduce switching losses during power conversion and contribute to greater application efficiency and lower power consumption.
