What castle has to say about that? Would it be good idea?
Already a TVS on the Mamba Monster. The TVS on the Monster is rated for over 2000A -- but it's the total power that is the limitation. You can't put a thousand watts into a 1 gram device and expect it to survive more than a few thousandths of a second. We are talking SERIOUS power here. The Mamba main FETs themselves can stand about 12000A of avalanche current -- but that's instantaneous current again. For four seconds of normal braking power (if the battery refused to take the power back) you can expect about 2000-8000 watt seconds of power that needs to be dissipated. There IS silicon that will take that kind of power -- but the chips are the size of hockey pucks.
