IRFP450
July 1999 File Number 2331.3
14A, 500V, 0.400 Ohm, N-Channel
Power MOSFET
This N-Channel enhancement mode silicon gate power field
effect transistor is an advanced power MOSFET 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 convertors, 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 TA17435.
