IRF840 Series RRooHHSS
Nell High Power Products
N-Channel Power MOSFET
(8A, 500Volts)
DESCRIPTION
The Nell IRF840 are N-Channel enhancement mode silicon
gate power field effect transistors. They are designed, tested
and guaranteed to withstand a specified level of energy in the
breakdown avalanche mode of operation.
They are designed as an extremely efficient and reliable
device for use in a wide variety of applications such as
switching regulators. convertors, UPS, switching mode power
supplies and drivers for high power bipolar switching
transistors requiring high speed and low gate drive power.
These transistors can be operated directly from integrated
circuits.
