GSIB2040N-M3/45

Overview

The GSIB2040N-M3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the GSIB-5S package and features glass passivated chip junctions. The device supports a maximum repetitive peak reverse voltage of 400 V and a maximum average forward rectified output current of 20 A at a case temperature of 87 °C, or 3.5 A on a PCB without a heatsink. Peak forward surge current capability reaches 240 A. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.0 V at 7.5 A and a maximum DC reverse current of 10 µA at 25 °C. Operating junction and storage temperatures range from -55 to +150 °C.

Feature Summary
