"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. " - Flyback电路反馈
