BRAND
The RF1K49157 Single 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 was 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 TA49157.
