Automotive Relay With Flyback Diode at Lynda Donohue blog

Automotive Relay With Flyback Diode. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. These are normal diodes, which are connected in parallel. 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 solution here, is to let the inductor “spin itself down” with a flyback diode. When the coil is energized, the flyback diode is. 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. How does a flyback diode work? 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. You need the flyback diodes because at the instant you open the switch, a relay's inductance will try to maintain the current. The diode connected across the relay coil is called a flyback diode or freewheeling diode. Flyback/snubber/freewheeling/etc diode for 12v automotive relay.
