WebFeb 8, 2024 · Yes, you should really use a diode with fast reverse recovery. A Schottky is a obvious choice at this low voltage. Schottkys have effectively instant reverse recovery for your purpose. The lower forward voltage of the Schottky will also cause less backwards EMF on the inductance during the off time, making the overall system more efficient. WebFeb 1, 2024 · The flyback diodes simply return the inductive spikes to the supply instead of generating excessive voltage which could destroy the transistors. The energy involved is normally relatively small and has little effect on a freewheeling motor. (And if it does, the effect can be minimised using the snubber tricks in Jack's answer).
