A Free wheeling diode is included across the coil to prevent/eliminate a condition called "flyback". Flyback: "A sudden voltage spike seen across an inductive load when its supply voltage is suddenly reduced or removed."

Features

• Freewheel diodes (also known as a snubber / suppressor diode) are used across inductive components such as relay coils to prevent voltage spikes when the power is turned off. When the coil is disconnected from an electromagnet, peaks of inverse voltage appear at the terminals which can reach very high values. These pulses can be transmitted down the line associated with the coil and could possibly affect other components. In the case of a relay being operated by such devices as transistors, triacs, etc; it may be necessary to protect against transients
