FQD4P40TM Description

Short technical summary and product information.

The FQD4P40TM is a P-Channel enhancement mode power MOSFET manufactured using ON Semiconductor's proprietary planar stripe DMOS technology. It is designed to minimize on-state resistance, provide superior switching performance, and withstand high energy pulses in avalanche and commutation modes.

 

Key specifications include a maximum drain-source voltage of -400V, continuous drain current of -2.7A at 25°C (derated to -1.71A at 100°C), and a maximum on-resistance of 3.1 Ohm at Vgs = -10V and Id = -1.35A. The device features low gate charge (typical 18nC) and low reverse transfer capacitance (typical 11pF), contributing to efficient switching performance.

 

The MOSFET is 100% avalanche tested, with a single pulsed avalanche energy rating of 260mJ. It is available in a surface-mount TO-252 (DPAK) package and is suitable for applications such as electronic lamp ballasts based on complementary half-bridge topologies.
