ABSTRACT:
A field effect transistor (FET) is used as the protection circuit. The gate is grounded through an electrical element. The voltage source is connected to the drain of the FET. The load is connected to the source of the FET. At low input voltages, the FET conducts in body diode mode. At higher input voltages, the FET turns “on” and conducts more efficiently.
