Claim:
1. A rectifier circuit configured to conduct current in a forward direction from an input to an output of the circuit, and substantially block current in a reverse direction from the output to the input, said circuit comprising: a metal-oxide-semiconductor-field-effect-transistor (mosfet) that defines a gate, a drain, a source, and a body-diode oriented to allow current to flow to the drain from the source of the mosfet, wherein the gate is connected to the input, the drain is connected to the output, and the mosfet is characterized by an on-resistance; and a first Zener-diode that defines an anode and a cathode of the first Zener-diode, wherein the cathode is connected to the input, the anode is connected to the source, and the first Zener-diode is characterized by a Zener-voltage, wherein the Zener-voltage and the on-resistance are selected such that a stored-charge in the body-diode is less than a forward-charge-threshold when current flows in the forward direction, whereby the reverse recover time of the body-diode is reduced.
