VSIB640-E3/45

Bridge Rectifier Overview

The VSIB640-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the GSIB-5S through-hole package and features glass passivated chip junctions. The device supports a maximum repetitive peak reverse voltage of 400 V and delivers a maximum average forward rectified output current of 2.8 A when mounted on a printed circuit board with specified copper pads. Key electrical parameters include a peak forward surge current of 180 A, a maximum instantaneous forward voltage drop of 0.95 V at 3.0 A, and a maximum DC reverse current of 10 µA at rated blocking voltage. The component operates within a junction temperature range of -55 °C to +150 °C.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. The E3 suffix indicates consumer grade compliance with whisker testing requirements. Confirm that the /45 designation corresponds to the tube packaging format defined in the manufacturer's ordering information. Cross-reference the exact part number with the latest datasheet revision to ensure compatibility with current manufacturing standards.

Bridge Rectifier Selection Notes

Select this component based on the required 400 V reverse voltage rating and the 2.8 A current capacity under PCB mounting conditions. Evaluate thermal management requirements using the provided junction-to-ambient thermal resistance values. Ensure the application environment remains within the specified -55 °C to +150 °C operating temperature range. Verify that the GSIB-5S package dimensions fit the target printed circuit board layout constraints.

Bridge Rectifier Part Context

This component belongs to the VSIB620 through VSIB680 series of single-phase single in-line bridge rectifiers. The series offers varying reverse voltage ratings from 200 V to 800 V while maintaining consistent current handling capabilities. All variants share the same GSIB-5S case style and mechanical characteristics, allowing for design flexibility across different voltage requirements within the same product family.

Bridge Rectifier Replacement Considerations

Direct replacement options within the same series include VSIB620-E3/45, VSIB660-E3/45, and VSIB680-E3/45. These alternatives maintain identical package dimensions and current ratings but differ in their maximum repetitive peak reverse voltage specifications. Ensure the substitute part meets or exceeds the 400 V requirement of the original design.
