STEF512GR ST eFuse | TSOT-23-8L | 5.5V, 5A, Adjustable Current Limit

Product Overview

The STEF512GR is an integrated electronic fuse (eFuse) from STMicroelectronics, designed to protect downstream circuitry from overcurrent, overvoltage, and short-circuit events. Housed in a compact TSOT-23-8L package, it offers a programmable current limit up to 5A and an input voltage range from 2.7V to 5.5V. The device features a fast response time, low on-resistance, and thermal shutdown protection, making it ideal for power distribution in space-constrained applications.
