Mosfet Without Body Diode Chart
If the body diode is 'Repetitive Avalanche Rated' then it's drawn as a zener simply because like an avalanche type zener, it can handle reverse current without self destructing with Vz equaling BVdss AFAIK most power mosfets can handle some avalanche energy but only some of them are guaranteed for it. Intrinsic MOSFET body-drain diode and Schottky features AN4789 4/16 DocID028669 Rev 1 2 Intrinsic MOSFET body-drain diode and Schottky features In Figure 1, the typical symbol for an N-channel power MOSFET is shown. The intrinsic body-drain diode is formed by the p-body and n-drift regions, and is shown in parallel to the MOSFET channel.
