IRFD120
1.3A, 100V, 0.300 Ohm, N-Channel
Power MOSFET
This advanced power MOSFET is designed, tested, and
guaranteed to withstand a specified level of energy in the
breakdown avalanche mode of operation. These are
N-Channel enhancement mode silicon gate power field
effect transistors designed for applications such as switching
regulators, switching convertors, motor drivers, relay drivers,
and drivers for high power bipolar switching transistors
requiring high speed and low gate drive power. They can be
operated directly from integrated circuits.
Formerly developmental type TA17401.
