Abstract :
Analyses of quasi-stationary avalanche simulations on radiation-hardened power MOSFETs suggest that the single-event burnout (SEB) failure is determined by the device´s avalanche characteristics and confirm SEB failure mechanism is due to the turn-on of parasitic bipolar transistor. The heavy ion beam is only acting as a trigger. Simulation results on various 600 V and 250 V radiation-hardened power MOSFETs from International Rectifier are compared to an extensive set of single event effect test results and prove quasi-stationary avalanche simulation is capable of evaluating and predicting SEB susceptibility
