75A, 55V, 0.008 Ohm, N-Channel UltraFET
Power MOSFETs
These N-Channel power MOSFETs
are manufactured using the
innovative UltraFET® 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.
