Planar to Trench: Short Circuit Capability Analysis of 1.2 kV SiC MOSFETs
This paper presents an insight into the short circuit (SC) capability of Rohm’s discrete 1.2 kV, 80 mΩ state-of-the-art silicon carbide (SiC) double trench metal-oxide-semiconductor field effect transistor (MOSFET). SC measurements are performed to compare the behavior of Wolfspeed’s similarly rated 1.2 kV, 80 mΩ planar MOSFET with the Rohm trench devices. Short circuit withstand time (SCWT) of both designs under nominal operating conditions at room temperature is measured by performing destructive SC tests.
