Fairchild FQPF11N40 N-Channel MOSFET Datasheet
The FQPF11N40 is a 400 V N‑Channel enhancement‑mode power MOSFET built with Fairchild’s planar stripe DMOS technology. It offers low gate charge, low output capacitance, fast switching and high avalanche capability, making it suitable for high‑efficiency switch‑mode power supplies and lamp ballast applications.
Key electrical specifications include a continuous drain current of 6.6 A at 25 °C, a pulsed drain current rating of 26 A, a gate‑source voltage rating of ±30 V, and a power dissipation of 50 W. The device is supplied in a TO‑220F package with a junction‑to‑case thermal resistance of 2.5 °C·W and a junction‑to‑ambient resistance of 62.5 °C·W.
