1N6761UR-1/TR

Overview

The Microchip Technology 1N6761UR-1/TR is a small-signal Schottky barrier rectifier designed for high-efficiency switching applications. It features a 100 V repetitive reverse voltage rating and a forward current capability suitable for low-power circuits. The device utilizes silicon technology to achieve a low forward voltage drop of 690 mV, minimizing power loss during conduction. Packaged in the DO-213AB MELF format, it supports operation across an extended temperature range from -65°C to +150°C junction temperature. This component offers fast recovery characteristics with minimal reverse leakage current, making it ideal for precision signal processing and protection tasks.
