Flyback Diode Solenoid. The above image shows the same inductor circuit but with additionally a flyback diode. That diode provides better electrical protection.
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. This diode is known by many other names such as snubber diode commutating diode freewheeling diode suppressor diode clamp diode or catch diode. You can tell the two diodes apart by the protective shrink sleeve on each.
It is used in circuits in which inductive loads are controlled by switches and in switching power supplies and inverters.
A flyback diode or freewheeling diode is placed with reverse polarity from the power supply and in parallel to the relay s inductance coil.
