The HUF76429D3ST is an N-Channel Logic Level UltraFET Power MOSFET manufactured by onsemi (formerly Fairchild Semiconductor). It is designed for high-efficiency power switching applications, offering a drain-to-source voltage rating of 60V and a continuous drain current of 20A at 25°C case temperature with a 10V gate drive.
This MOSFET features ultra-low on-resistance, with a maximum of 23mΩ at VGS = 10V and 20A, and a typical value of 27mΩ at VGS = 5V. The gate threshold voltage is 3V maximum at 250µA, and the device supports drive voltages of 4.5V and 10V, making it suitable for logic-level drive circuits. The input capacitance is 1480pF at 25V, and the total gate charge is 46nC at 10V, enabling fast switching.
The device is rated for a maximum power dissipation of 110W at case temperature, and it operates over a junction temperature range of -55°C to 175°C. It is housed in a TO-252AA (DPak) surface-mount package, which is suitable for automated assembly and space-constrained PCB layouts.
Typical applications include power supplies, DC-DC converters, motor control, and load switching in industrial and consumer electronics. The HUF76429D3ST is part of the UltraFET family, known for low on-resistance and robust performance.
The maximum drain-to-source voltage (Vdss) is 60V.
The continuous drain current is 20A at Tc=25°C with VGS=10V.
The maximum on-resistance is 23mΩ at VGS=10V and 20A; typical values are 27mΩ at VGS=5V and 23mΩ at VGS=10V.
The operating junction temperature range is -55°C to 175°C.
The device is available in a TO-252AA (DPak) surface-mount package, also known as TO-252-3 (2 leads + tab).
The RoHS status is listed as RoHS3 compliant, but this is unverified and should be confirmed with the manufacturer.
