Description

These are N-Channel enhancement mode silicon gate

power field effect transistors. They are advanced power

MOSFETs designed, tested, and guaranteed to withstand a

specified level of energy in the breakdown avalanche mode

of operation. All of these power MOSFETs are designed for

applications such as switching regulators, switching conver-

tors, 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 TA17405.
