Progress in SiC MOSFET Reliability
ECS Transactions, 2013 Bias-temperature stress experiments performed on two generations of SiC power MOSFETs from the same manufacturer show reductions in threshold voltage (VT) shift at elevated temperatures from first- to second-generation. The negative VT shift is reduced from a range of -1 V to -1.6 V to a range of -100 mV to -300 mV for temperatures from 125°C to 175°C.
