RF1K49086
3.5A, 30V, Avalanche Rated, Dual N-Channel
Description
The RF1K49086 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 device can be operated directly from integrated circuits.
Formerly developmental type TA49086.
