Diode Purpose In Relay at Sara Lourdes blog

Diode Purpose In Relay. This permits the relay to have optimum release. When the inductive load is a relay, the flyback diode can noticeably delay the release of the relay by keeping the coil current flowing longer. 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 is there to suppress this voltage so that it cannot damage any components around the relay, such as the transistor and the external battery supply. Here's an example schematic i found online: 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. The purpose of a diode connected in parallel to a relay coil (flywheel diode or freewheeling diode) is to avoid damaging some nearby components. Adding a diode will create an easy path. The suggested technique for relay coil suppression is to used a reverse biased rectifier diode and a series zener diode in parallel with the coil. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes.
