Description
These are N-Channel enhancement mode silicon gate
power field effect transistors specifically designed for applications such as switching regulators, switching converters,
motor drivers, relay drivers, and drivers for high power bipolar switching transistors requiring high speed and low gate
drive power. These types can be operated directly from integrated circuits.
Formerly developmental type TA17425.
