Emf Diode Diagram. Theres once a joke that says a 50 transistor will often blow first to protect a 10 cent. Yes the body diodes in the other mosfets divert the back emf back into the supply.

The sum of all the contact potentials is zero and so they may be ignored in kirchhoffs law. R1 vin vout i.
A flyback diode is a diode connected across an inductor used to eliminate flyback which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.
Chapter 21 2 voltage and current in rlc circuits îac emf source. When the power supply is removed the voltage polarity on the coil is inverted and a current loop forms between the relay coil and protection diode. R1 vin vout i. Thus when the motor turns off the diode presents a short circuit to the back emf allowing it to dissipate safely.
