Do You Need A Diode Across Relay Coil. The diode is often the. 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. You can easily make a relay driver circuit with a transistor, a current limiting resistor (to turn the transistor on and off), and a diode in parallel with the relay coil. So in order to prevent damage to the semiconductor transistor, a “flywheel diode”, also known as a freewheeling diode, is connected across the relay coil. The suggested technique for relay coil suppression is to used a reverse biased rectifier diode and a series zener diode in parallel with. Do all relays need a diode, no, not all, only about 90% of them do. In your circuit if you build it for real you'll see sparking in the switch. The purpose of a diode connected in parallel to a relay coil (flywheel diode or freewheeling diode) is to avoid damaging some nearby components. Here's an example schematic i found online: Placing a diode across a relay coil passes the back electromagnetic field and its current through the diode when the relay is energized as the back emf drives the flyback protection diode in forward bias. In this article, we will.
