FQD6N40CTM Description

Short technical summary and product information.

The FQD6N40CTM is an N-Channel enhancement mode power MOSFET manufactured by onsemi using their proprietary planar stripe and DMOS technology. This device is designed to deliver efficient switching performance with a low on-state resistance of 1.0 Ohm maximum at Vgs=10V and Id=2.25A.

 

Key electrical specifications include a drain-source breakdown voltage of 400V, continuous drain current of 4.5A at 25°C case temperature, and a pulsed drain current capability of 18A. The MOSFET offers a typical gate charge of 16 nC and a typical reverse transfer capacitance of 15 pF, contributing to reduced switching losses. It is 100% avalanche tested with a single pulsed avalanche energy rating of 270 mJ.

 

The device is housed in a surface-mount DPAK (TO-252AA) package, suitable for automated assembly. It supports an operating junction temperature range of -55°C to 150°C and has a maximum power dissipation of 48W at 25°C case temperature. The gate-source voltage rating is ±30V.
