A circuit and method for reducing the reverse leakage current in a reverse-biased diode device, such as a Schottky diode, is disclosed. The diode device is electrically coupled between an N-channel depletion mode device and a P-channel depletion mode device, and the gates of the depletion mode devices are electrically coupled to opposite terminals of the circuit so that both are either in an ON state or an OFF state, based on a voltage applied to terminals of the circuit. When the circuit is forward-biased both depletion mode devices are in an ON state and when the diode device is reversed biased both the depletion mode devices are in the OFF state. The depletion mode devices in the OFF state reduce a reverse leakage current of the diode device. This reduction is useful for applications that require efficient diode operation, such as solar cell systems.
