Flyback diode or suppression circuit protects inductive loads from voltage spikes during switching in output driver circuits.
A flyback diode, also known as a freewheeling diode, snubber diode, or suppression circuit, is a diode connected across an inductive load such as a relay coil, solenoid, or motor winding in an output driver circuit. Its primary function is to provide a safe path for the inductive current to decay when the driving transistor or switch turns off, preventing high-voltage transients (back EMF) that could damage sensitive electronic components.

It prevents damaging voltage spikes caused by inductive kickback when switching off inductive loads, protecting transistors, ICs, and other components from overvoltage failure.
No, it must have sufficient reverse voltage rating to handle the spike, adequate current rating for the inductive load, and appropriate speed (fast recovery for high-frequency circuits). Standard silicon rectifier diodes like 1N4007 are common for general purposes.
Without it, the back EMF can exceed the breakdown voltage of the driving switch, causing arcing, component destruction, electromagnetic interference (EMI), and system malfunction.
