    Abstract: An ORing element for use in a power supply and/or power system. The ORing element may include a field effect transistor (FET), a first bi-polar transistor and a second bi-polar transistor. The FET may be electrically connected between an input and an output. The first bipolar transistor may have an emitter electrically connected to the source of the FET and a collector electrically connected to a gate of the FET. The second bi-polar transistor may be diode connected, with its emitter electrically connected to its base. The emitter of the second bi-polar transistor may also be electrically connected to the base of the first bi-polar transistor. The collector of the second bi-polar transistor may be electrically connected to the drain of the FET.
