The IRF840APBF is an N-Channel enhancement-mode power MOSFET designed for high-voltage switching applications. It offers a drain-source voltage rating of 500V and a continuous drain current of 8A at 25°C case temperature, with a maximum on-resistance of 850mΩ at 10V gate drive.
This device features low gate charge (38nC total) and is characterized for avalanche energy and dynamic dV/dt ruggedness, making it suitable for switch-mode power supplies and high-speed power switching circuits. The MOSFET is built with planar stripe technology and is available in the industry-standard TO-220AB through-hole package.
Typical applications include two-transistor forward converters, half-bridge and full-bridge topologies, and uninterruptible power supplies. The part is offered with lead-free terminations and is RoHS-compliant per the datasheet ordering information.
