Incorporating SiC power MOSFETs is very attractive for advancing power electronic system performance, yet the system reliability with new devices remains in question. This work presents an overview of accelerated lifetime tests and the packaging and semiconductor failure mechanisms they excite. The experiments explained here includes High Temperature Gate Bias (HTGB), Switching Cycling, Power Cycling, and Thermal Cycling. These experiments stress different failure mechanisms, that show degradation in different device parameters including, but not limited to, threshold voltage and on-resistance. These four experiments help illustrate the spectrum between device and package degradation that can be used to design more reliable power electronic circuits.
