A protection diode is used in a circuit so that current will not flow in the reverse direction in the circuit. For example if your power supply provides 12 v at 07 a of current you may wish to select a diode that has a reverse breakdown voltage of 15v and 1a of forward current. A Dc Fault Protection Circuit For Audio Amplifiers Datasheet Place Decoupling Capacitor Before Or After The Reverse This helps to protect components in circuitry that can be damaged from reverse current. Protection diode power supply . In some situations where the input voltage is higher than expected we always use an overvoltage protection or crowbar protection circuit. Overvoltage protection is a characteristic of a power supply system which somehow deals with the voltage across the load side when the input voltage exceeds the pre set value. If you have trouble finding a diode that ...
