The RFD14N05L from Fairchild is a through hole, 50V N channel logic level power MSOFET in TO-251AA package. Transistor is produced using megaFETprocess uses feature sizes approaching those of LSI integrated circuits, gives optimum utilization of silicon, resulting in outstanding performance MOSFET has an special gate oxide design which provides full rated conductance at gate bias in the 3V to 5V range, thereby facilitating true on-off power control directly from logic level (5V) integrated circuits. Typical applications are switching regulators, switching converters, motor drivers and relay drivers.
