Data Sheet January 2003
47A, 30V, 0.021 Ohm, N-Channel, Logic Level UltraFET Power MOSFETs
These N-Channel power MOSFETs are manufactured using the innovative UltraFETTM process. This advanced process technology achieves the lowest possible on-resistance per silicon area, resulting in outstanding performance. This device is capable of withstanding high energy in the avalanche mode and the diode exhibits very low reverse recovery time and stored charge. It was designed for use in applications where power efficiency is important, such as switching regulators, switching converters, motor drivers, relay drivers, lowvoltage bus switches, and power management in portable and battery-operated products. Formerly developmental type TA76121.
