Fairchild FQPF17N08L N-Channel MOSFET Datasheet
The FQPF17N08L is an 80 V logic‑level N‑Channel MOSFET built with Fairchild's planar stripe DMOS technology. It offers low on‑state resistance, low gate charge, and robust avalanche performance, making it suitable for low‑voltage, high‑efficiency switching applications such as motor control and DC‑DC converters.
Key electrical characteristics include a continuous drain current of 11.2 A at 25 °C, pulsed current capability of 44.8 A, gate‑source voltage rating of ±20 V, and a typical total gate charge of 8.8 nC. The device is supplied in a TO‑220F package with a junction‑to‑case thermal resistance of 5 °C·W and a junction‑to‑ambient resistance of 62.5 °C·W.
