STEF01FTR ST Electronic Switches | 14-TSSOP Exposed Pad | 0.5A-2A, 2.7V-18V

Product Overview

The STEF01FTR is a fully integrated electronic fuse from STMicroelectronics, designed to protect downstream circuitry from overcurrent, overvoltage, and short-circuit events. Housed in a compact 14-TSSOP package with an exposed pad for enhanced thermal dissipation, this device offers a programmable current limit from 0.5 A to 2 A and operates over a wide input voltage range of 2.7 V to 18 V. Its low on-resistance (typical 85 mΩ) minimizes power loss, making it ideal for power distribution in industrial, automotive, and consumer applications.
