RF1K49090

3.5A, 12V, 0.050 Ohm, Logic Level, Dual

N-Channel LittleFET™ Power MOSFET

This Dual N-Channel power MOSFET is manufactured using

an advanced MegaFET process. This process, which uses

feature sizes approaching those of LSI integrated circuits,

gives optimum utilization of silicon, resulting in outstanding

performance. It is designed for use in applications such as

switching regulators, switching converters, motor drivers,

relay drivers, and low voltage bus switches. This product

achieves full rated conduction at a gate bias in the 3V - 5V

range, thereby facilitating true on-off power control directly

from logic level (5V) integrated circuits.

Formerly developmental type TA49090.
