Data Sheet September 2013 RFP70N06 N-Channel Power MOSFET 60V, 70A, 14 mΩ These are N-Channel power MOSFETs manufactured using the MegaFET process. This process, which uses feature sizes approaching those of LSI 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 and relay drivers. These transistors can be operated directly from integrated circuits. Formerly developmental type TA78440. Ordering Information PART NUMBER RFP70N06 PACKAGE TO-220AB BRAND RFP70N06 NOTE: When ordering use the entire part number.
