Abstract :
This paper reports, for the first time, a mechanism, which limits the safe operating area (RBSOA). We numerically verify that a RBSOA limiting mechanism is that the device breakdown voltage dynamically reduces when the net positive sheet charge in the SOI layer exceeds the optimum positive sheet charge determined by the SOI-Resurf principle. It was found that the forward SOA for the steady conduction state is far larger than the reverse SOA for switching transients
