STEF12EPUR ST Electronic Circuit Protection | 10-DFN（3x3） | 12V, 5A, 30mΩ

Product Overview

The STEF12EPUR is an electronic fuse (eFuse) from STMicroelectronics, designed for overcurrent and overvoltage protection in power distribution systems. It integrates a low-resistance power MOSFET (30mΩ typical) and a controller in a compact 10-DFN (3x3mm) package. The device operates from 2.7V to 18V, supports continuous current up to 5A, and features programmable current limit, output slew rate control, and thermal shutdown. It is ideal for hot-swap, USB, and general power rail protection.
