WebThe flyback voltage generated by inductive loads can potentially damage the component being used to open and close the circuit. In the case of a physical switch, … 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.
