SI5944DU-T1-E3

Overview

The Vishay Siliconix SI5944DU-T1-E3 is a dual N-channel MOSFET utilizing TrenchFET technology. It features a 40 V drain-source voltage rating and operates within a junction temperature range of -55 °C to +150 °C. The device provides a maximum on-state resistance of 0.112 Ω at VGS = 10 V and 0.171 Ω at VGS = 4.5 V. Continuous drain current reaches 6 A when the case is held at 25 °C, with a total gate charge typically measuring 2.2 nC at VGS = 10 V. It is housed in a leadless PowerPAK ChipFET Dual 8 package.

Feature Summary

TrenchFET power MOSFET architecture for low on-resistance
Thermally enhanced PowerPAK ChipFET package with small footprint
Halogen-free compliant construction

Applications

DC-DC power supply circuits
