11A, 60V, 0.107 Ohm, Logic Level,
N-Channel Power MOSFETs
These N-Channel enhancement-mode power MOSFETs are
manufactured using the latest manufacturing process
technology. This process, which uses feature sizes
approaching those of LSI circuits, gives optimum utilization
of silicon, resulting in outstanding performance. They were
designed for use in applications such as switching
regulators, switching converters, motor drivers and relay
drivers. These transistors can be operated directly from
integrated circuits.
Formerly developmental type TA49158.
