Why Do Relays Have Diodes at Eugene Eric blog

Why Do Relays Have Diodes. Why should you use a diode in a relay driver circuit? The diode across the relay coil is there to prevent emf from the coil. A resistor in series with the diode can make the relay fall off. A diode parallel to the coil is probably the most often used way, but there are other ways, like a snubber (r+c) or a zener diode to ground. Machine controls that have relays switching relays typically don't have diodes (especially if the coils are ac) or snubbers. A relay is commonly used to drive large electrical loads. Why is there a diode connected in parallel to a relay coil? With a relay, your arduino can control large motors,. Adding a diode will create an easy path for this current to. The purpose of a diode connected in parallel to a relay coil (flywheel diode or freewheeling diode) is to avoid damaging some nearby. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. You need the flyback diodes because at the instant you open the switch, a relay's inductance will try to maintain the current. This is a pretty common question that i get asked, so i figured it was a good time to put together a tutorial on why flyback / snubber. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. The transistor provides current gain, and a small input current can switch the relatively large current need to.
