Data Sheet August 1999 File Number

7A, 12V, 0.020 Ohm, Logic Level, Single
N-Channel LittleFET™ Power MOSFET

The RF1K49211 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 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 TA49211.
