Automotive Relay With Flyback Diode. Here's an example schematic i found online: Relays / relay sockets have diodes to suppress flyback voltage spikes and prevent damage to switch contacts / transistors. Flyback/snubber/freewheeling/etc diode for 12v automotive relay. A diode is put in parallel with a relay coil (with opposite polarity) to prevent damage to other components when the relay is turned off. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. How does a flyback diode work? In a typical relay circuit, the flyback diode is connected in parallel to the relay coil but oriented in reverse, so it blocks current flow under. The diode connected across the relay coil is called a flyback diode or freewheeling diode. These are normal diodes, which are connected in parallel. When the coil is energized, the flyback diode is. You need the flyback diodes because at the instant you open the switch, a relay's inductance will try to maintain the current. The solution here, is to let the inductor “spin itself down” with a flyback diode.
