WebThe 2N7000 is however low cost and one can try to obtain more power in any design by increasing the drive level, putting several of the FETs in parallel (unlike BJTs, FETs are well suited to being stacked in parallel because of their negative current vs temperature characteristics.. i.e. unlike BJTs, FETs do not suffer from thermal runaway) and other … WebWhen the MOSFET is turned off, a negative voltage is created between GaN HEMT gate and its source terminal ... if they do not cause complete device failure due to thermal runaway or dielectric breakdown in the long term . Moreover, a typical GaN transistor has an almost square SOA due to absence of second breakdown mechanism or ... WebHowever, this is not the case when the MOSFETS are conducting in the reverse direction through the body diode. The forward voltage of the body diode decreases with a temperature rise and enables more flow of current through it. With time, the current imbalance increases and causes thermal runaway, damaging the MOSFETs in parallel. east burke high school maribeth icard
