A flyback diode is any 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. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters. 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.
