WebMar 2, 2006 · NPN bipolar junction transistor (BJT), and turning it on is definitely not part of normal operation. If the BJT were to turn on and saturate, it would result in a condition called latchup, where the MOSFET cannot be turned off except by externally interrupting the drain current. High power dissipation during latchup can destroy the device. rbz exchange rates 31 december 2021 https://pickfordassociates.net
