The FDMT80040DC is an N-Channel MOSFET built on onsemi's advanced PowerTrench process, combined with the Dual Cool package technology to achieve extremely low on-resistance and high current capability. It is rated for a maximum drain-source voltage of 40V and a continuous drain current of 420A at Tc=25°C, with a maximum on-resistance of 0.56mΩ at Vgs=10V and Id=64A. The device supports gate drive voltages of 6V and 10V, and features a low gate charge of 338nC and input capacitance of 26110pF, enabling efficient switching in high-power applications.
This MOSFET is designed for use in ORingFET/load switching, synchronous rectification, and DC-DC conversion circuits. Its low thermal resistance (0.8°C/W junction-to-case) and robust package design (8-PowerVDFN, Dual Cool) allow effective heat dissipation in space-constrained layouts. The device is Pb-free, halide-free, and RoHS compliant, with MSL1 rating for unlimited floor life.
Typical applications include high-efficiency power supplies, server and telecom power converters, and battery management systems where low conduction losses and high current handling are critical. The surface-mount package is suitable for automated assembly and supports a wide operating junction temperature range of -55°C to +150°C.
