18A, 200V, 0.180 Ohm, N-Channel Power
MOSFETs
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
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 TA17422.
