STEF033APUR ST Power Switch | 10-VFDFN 祼焊盘 | 3A, 2.7-18V

Product Overview

The STEF033APUR is a fully integrated 3A power switch from STMicroelectronics, designed for hot-swap and overcurrent protection in 2.7V to 18V applications. Housed in a compact 10-VFDFN exposed pad package, it features low on-resistance (35mΩ typical) and fast response to short circuits. The device integrates a power MOSFET, current sense, and thermal protection, making it ideal for robust power management in industrial and automotive systems.
