Fairchild FQPF9N30 300V N-Channel MOSFET Datasheet
The FQPF9N30 MOSFET is a 300 V N‑Channel enhancement mode power transistor built with Fairchild’s planar stripe DMOS technology. It is designed for high‑efficiency switching in DC/DC converters and switch‑mode power supplies.
Key specifications include a continuous drain current of 6 A at 25 °C, a pulsed rating of 24 A, low on‑resistance (0.452 Ω at VGS=10 V), typical gate charge of 17 nC, and robust avalanche capability (100 % tested). The device is supplied in a TO‑220F package and is suitable for high‑power, high‑speed applications.
