WebOnline monitoring results show that the ON-state voltage drop of SiC MOSFET continuously rises with the increase of stress times. The increase in ON-state voltage is caused by the change of package resistance and channel resistance. Gate oxide degradation resulting in a large increase in drain-source leakage current and gate leakage current. WebDec 9, 2024 · The effect of SFs on the on-resistance and the forward leakage current in a 10 kV SiC MOSFET was first reported by Agarwal et al. in 2007. The body diodes are expected to degrade more in thicker or high voltage epilayers due to the bigger size of the stacking fault. ... Han, J.K.; Baliga, B.J.; Sung, W.
