The FQAF13N50 is a 500 V N‑Channel enhancement mode power MOSFET built with Fairchild’s planar stripe DMOS technology. It offers low gate charge (typical 45 nC), low output capacitance (typical 25 pF), fast switching, and 100 % avalanche testing, making it suitable for high‑efficiency switch‑mode power supplies and power‑factor‑correction circuits.
Key specifications include a continuous drain current of 9.6 A at 25 °C, pulsed drain current of 38.4 A, a drain‑source voltage rating of 500 V, and a power dissipation capability of 100 W. Thermal resistance values are 1.25 °C·W (junction‑to‑case) and 40 °C·W (junction‑to‑ambient). The device is supplied in a TO‑3PF package.
