Abstract
It was demonstrated that single-event burnout (SEBs) was observed in silicon carbide power MOSFETs caused by heavy ion and proton irradiations. In addition to SEBs, permanent damage (increase of the drain leakage current) was also observed with higher LET ions similar to SiC Schottky Barrier diodes. For lower LET ions including protons, there were no leakage current increase just before SEBs were observed. The phenomenon is unique for SiC devices.
