What Does A Diode Do In A Relay. Do all relays need a diode, no, not all, only about 90% of them do. In relay circuits, flyback diodes play a critical role in protecting sensitive components from voltage spikes caused by the collapsing magnetic field. Here's an example schematic i found online: The diode across the relay coil is there to prevent emf from the coil. With a relay, your arduino can control large motors, led strips, lights, etc. 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. 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. Diode across the relay coil helps to short circuit the reverse emf spike from the relay coil whenever the relay is switched off. But without a simple diode, your circuit can be easily damaged. The transistor provides current gain, and a small input current can switch the relatively large current need to. A resistor in series with the diode can make the. In your circuit if you build it for real you'll see sparking in the switch.
