The RFP70N03, RF1S70N03, and RF1S70N03SM N-Channel power MOSFETs are manufactured using the MegaFET process. This process, which uses feature sizes approach ing those of LSI integrated circuits gives optimum utilization of silicon, resulting in outstanding performance. They were designed for use in applications such as switching regulators, switching converters, motor drivers, relay drivers and emitter switches for bipolar transistors. These transistors can be operated directly from integrated circuits.
