Fairchild FQAF22N30 N-Channel MOSFET Datasheet
The FQAF22N30 is a 300 V N‑Channel enhancement mode power MOSFET designed for high‑efficiency switching applications such as DC/DC converters and switch‑mode power supplies. It features low gate charge, low output capacitance, fast switching, and robust avalanche capability.
Key specifications include a continuous drain current of 16 A at 25 °C, a pulsed drain current rating of 64 A, a typical on‑resistance of 0.12 Ω at Vgs = 10 V, and a total gate charge of about 47 nC. The device can dissipate up to 100 W (25 °C) and operates over a temperature range of –55 °C to +150 °C.
