Hello, I am designing a motor controller, and I was curious about the MOSFETs I'm using that have an internal body diode zener for Vds protection that is common in a lot of datasheets. I am switching the coils of the inductor with these MOSFETs, and I would like to know if its unwise to assume to use the internal zener diode of the MOSFET as my flyback diode when I am switching the inductor. The part I'm using is IRFP3206 and I see the max pulsed current is 840 Amps for the FET's diode, and I can do the calculations to approximate the flyback current, so I think it is ok to use. But, I just am cautious to use the internal diode for a specific function, when it seems like it is put in more to protect the FET junctions as a general purpose protection. Is this done in practice?
