HUF76437S3ST Description

Short technical summary and product information.

The HUF76437S3ST is an N-Channel logic level UltraFET power MOSFET from On Semiconductor (formerly Fairchild Semiconductor). It features a maximum drain-to-source voltage of 60V and a continuous drain current of 71A at 25°C with 10V gate drive. The device offers ultra-low on-resistance: 14mOhm maximum at Vgs=10V and 17mOhm typical at Vgs=5V, enabling efficient power switching.

This MOSFET is designed for logic level gate drive with a drive voltage range of 4.5V to 10V. It has a maximum gate charge of 71nC and input capacitance of 2230pF, contributing to fast switching performance. The operating junction temperature range is -55°C to 175°C, with a maximum power dissipation of 155W at case temperature 25°C.

The HUF76437S3ST is supplied in a surface mount D²PAK (TO-263-3) package with tape and reel packaging for automated assembly. It is suitable for DC-DC converters, power supplies, motor control, and load switching applications where high efficiency and compact design are required.
