GSIB2080N-M3/45

Overview

The GSIB2080N-M3/45 is a single-phase, single in-line bridge rectifier from Vishay General Semiconductor. It features an 800 V maximum repetitive peak reverse voltage and a 20 A average forward rectified output current at a case temperature of 87 °C. The device utilizes a glass passivated chip junction within a GSIB-5S package. 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. The component supports a peak forward surge current of 240 A and operates within a junction temperature range of -55 to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge current capability with 240 A rating
• Thin single in-line package design
• High case dielectric strength of 2500 V RMS

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Home appliances
• Office equipment
• Industrial automation applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status. The M3 suffix indicates halogen-free, RoHS-compliant, commercial grade material. Confirm that the base part number matches the required voltage rating before procurement. Ensure the delivery mode aligns with project requirements, as packaging options vary by manufacturer specifications.

Selection Notes

Select this component based on the 800 V reverse voltage requirement and 20 A continuous current capacity. Consider thermal management strategies, as the average forward current derates significantly when mounted on a PCB without a heatsink compared to aluminum plate mounting. Verify that the operating environment stays within the specified -55 to +150 °C junction temperature range.

Part Context

This component belongs to the GSIB20xxN series of single-phase single in-line bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, specifically 200 V, 400 V, 600 V, and 800 V. All models share the same GSIB-5S package style and similar electrical characteristics regarding current handling and surge capabilities.
