Inhalt:
This work analyzes the onset of gate oxide breakdown of different discrete 1.2 kV SiC MOSFETs for different gate voltage steps. The devices were tested at the same high temperature and the gate voltage was increased step by step. The research on this breakdown distribution is necessary to prove if SiC MOSFETs can fulfill the same reliability requirements for power electronic devices, which are also applicable for current IGBTs.
