VSIB2520-E3/45

Bridge Rectifier Overview

The VSIB2520-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 for reliability. The device supports a maximum repetitive peak reverse voltage of 200 V and delivers a maximum average forward rectified output current of 25 A when case-mounted on an aluminum plate heatsink at 98 °C, or 3.5 A when mounted on a PCB without a heatsink at 25 °C ambient temperature. It exhibits a maximum instantaneous forward voltage drop of 1.0 V per diode at 12.5 A and a peak forward surge current capability of 350 A.

Bridge Rectifier Feature Summary

• Glass passivated chip junction construction
• High surge current capability with 350 A rating
• High case dielectric strength of 2500 V RMS
• Epoxy casing meets UL 94 V-0 flammability rating

Bridge Rectifier Applications

• AC-to-DC bridge full wave rectification in switching power supplies
• Home appliances
• Office equipment
• Industrial automation applications

Bridge Rectifier Procurement Notes

Verify component authenticity against official Vishay documentation before integration. Confirm that the specific ordering suffix matches the required package code and base quantity specifications. Ensure compliance with RoHS 2002/95/EC and WEEE 2002/96/EC directives as stated in the datasheet. Validate thermal management requirements based on the selected mounting configuration to maintain safe operating temperatures.

Bridge Rectifier Selection Notes

Select this component for general purpose AC-to-DC rectification where high surge current handling is required. Evaluate thermal resistance parameters carefully; use an aluminum plate heatsink to achieve the rated 25 A current capacity. For PCB-only mounting without additional cooling, limit the average forward current to 3.5 A. Verify that the 200 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.

Bridge Rectifier Part Context

This part belongs to the VSIB2520 thru VSIB2580 series of single-phase single in-line bridge rectifiers from Vishay. The series offers varying reverse voltage ratings from 200 V to 800 V while maintaining a consistent 25 A average forward current rating under optimal heatsinking conditions. All variants share the same GSIB-5S case style and mechanical dimensions.

Bridge Rectifier Replacement Considerations

Direct substitute: VSIB2540-E3/45 (400V), VSIB2560-E3/45 (600V), VSIB2580-E3/45 (800V). These parts share identical electrical characteristics except for the maximum repetitive peak reverse voltage rating.
