Webthe body diode and the parasitic bipolar junction transistor (BJT) are formed. The reverse diode is a result of P+ body diffusion into the N epi, and the BJT is formed when the N+ source contact is diffused on top. It should be remembered that the schematic is only a lumped representation. 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.
