49A, 55V, 0.022 Ohm, N-Channel UltraFET
Power MOSFET
This N-Channel power MOSFET is
manufactured using the innovative
UltraFET鈩?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
ef鏗乧iency is important, such as switching regulators,
switching converters, motor drivers, relay drivers, low-
voltage bus switches, and power management in portable
and battery-operated products.
Formerly developmental type TA75329.
