Doesn't D24 do the same thing as the body diode on the internal NMOS? Is the assumption that the IR2102 doesn't have body diodes or maybe they just are not good enough to handle the voltage change as cupoftea was alluding to:
Initially I was thinking that D24 had some kind of flyback/freewheeling characteristics to it, but what I am hearing now is that it is maybe used for MOSFET protection? The FCB20N60 has a max Vgs of +/- 30V, so I found it interesting that they went with a reverse breakdown value of 40V. I would...
I am working with a bootstrapped half bridge gate driver and I am wondering if anyone knows what function D24 is performing in the below image? I can't find this specific diode placement in any of the other circuits that I have found online. Thanks.
