Nell High Power Products

IRF840 Series

(8A, 500Volts)

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.
