WebSep 8, 2024 · A flyback diode is placed with reverse polarity from the power supply and in parallel to the relay’s inductance coil. The use of a flyback diode in a relay circuit prevents huge voltage spikes from arising when the power supply is disconnected. They are sometimes called flywheel diodes, freewheeling diodes, relay diodes, or snubber diodes. Webfeetwet. 2,322 9 30 55. 2. "Flyback" is a play on words, the same as "bootstrap" is for amplifiers and software. It is a way of feeding some of the output back to an input stage to boost performance. The term originated in the 1950's with the HV flyback transformer for the picture tube.
