Thanks!
Suppose there was a super high voltage spike and the MOSFET was in its offstate.
In a situation without a flywheel diode I would expect the mosfet to look like an open circuit and current would try to flow through the mosfet into ground, potentially killing it. What would be the benefit of having MOSFET with a built in diode conducting the other way in this situation? Wouldn't that imply the current was moving upwards? (I thought inductors hated change in current, so they should conduct in the same direction). It seems to me that the diode would only be beneficial if it was parallel accross the inductor itself, so the current would flow to the lower potential which is the positive terminal of a battery.
Sorry if I'm not understanding. Thanks!
