How pick/calculate flyback diode current value?

WebIn general, a flyback diode is called a snubber. There are several types of snubbers, and a diode is a simple solution. The downside to diodes is that they need a voltage drop to conduct, meaning that they do not start conducting as soon as possible, but that you need to add 0.6V across them for the idea to work. WebFeb 21, 2024 · Short answer: select a diode with a reverse voltage rating (often expressed as "peak inverse voltage", abbreviated "PIV") a bit higher than the power supply voltage and with a forward current rating greater than or equal to the relay coil operating current. Long answer: A relay coil is an inductor. rayland baxter yellow eyes chords
