WebFeb 14, 2024 · The overload will also affect any other paralleled MOSFET gates. Thus it’s best to check the drive circuits of dead MOSFETs. To avoid overloads, some designers add a zener diode between the source and gate–zeners fail short so they can limit damage in the event of a MOSFET failure. Another tactic is to add subminiature gate resistors. 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.
