Data Sheet
RFK25N18, RFK25N20
October 1998
File Number 1500.3
25A, 180V and 200V, 0.150 Ohm,
N-Channel Power MOSFETs
These are N-Channel enhancement mode silicon gate
power field effect transistors 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 TA09594.
