Breakdown Voltage Sic

Breakdown Voltage Sic. Breakdown during high voltage application due to the occurrence of an electric field concentration because the breakdown electric field strength of sic is 10 times higher •breakdown extrapolations show that expected oxide lifetime is high (1×108 hrs) at use voltage (20 v gs gen2, 15 v gs gen3) •even rough, thicker sic epi does not impact oxide breakdown significantly •thus, oxide trap states or sic epi defects do not observably impact oxide lifetime tddb summary
