GSIB640N-M3/45

Overview

The GSIB640N-M3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing the GSIB-5S through-hole package. It features a maximum repetitive peak reverse voltage of 400 V and supports a maximum average forward rectified output current of 6.0 A at a case temperature of 100 °C. The device exhibits a maximum instantaneous forward voltage drop of 0.95 V at 3.0 A and a peak forward surge current capability of 180 A. Operating junction temperatures range from -55 °C to +150 °C, with a maximum thermal resistance of 22 °C/W when mounted on a PCB.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High case dielectric strength rated at 1500 V RMS
• Thin single in-line package design for compact mounting
• Matte tin plated leads compliant with JESD 201 class 1A whisker test

Applications

• AC/DC bridge full wave rectification in switching power supplies
• Rectification circuits within home appliances
• Power conversion stages in office equipment
• Industrial automation control systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 89385 and revision date against official Vishay channels. Confirm that the M3 suffix indicates halogen-free and RoHS compliance as specified in the datasheet. Ensure procurement sources provide traceability documentation matching the GSIB-5S package style and electrical ratings defined in the primary characteristics table.

Selection Notes

Select this component when a 400 V blocking voltage and 6.0 A continuous current rating are required in a thin single-in-line form factor. Evaluate thermal management requirements based on the 22 °C/W junction-to-ambient resistance for PCB mounting applications. Consider the 180 A surge current capability for circuits experiencing high inrush loads during startup phases.

Part Context

This part belongs to the GSIB620N through GSIB680N series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. All variants share identical mechanical dimensions, thermal characteristics, and packaging standards while differing primarily in their maximum repetitive peak reverse voltage ratings ranging from 200 V to 800 V.

Replacement Considerations

Direct substitutes within the same series include GSIB620N-M3/45, GSIB660N-M3/45, and GSIB680N-M3/45. These alternatives maintain identical physical and thermal specifications but offer different voltage ratings of 200 V, 600 V, and 800 V respectively.
