VSIB2580-E3/45

Bridge Rectifier Overview

The VSIB2580-E3/45 is a single-phase bridge rectifier from the VSIB25 series manufactured by Vishay General Semiconductor. It utilizes glass passivated chip junctions within a GSIB-5S single in-line package. The device supports a maximum repetitive peak reverse voltage of 800 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 features a peak forward surge current capability of 350 A and a maximum instantaneous forward voltage drop of 1.0 V per diode at 12.5 A. The component operates within a junction and storage 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 JESD 201 class 1A whisker testing standards. Confirm that the /45 package code corresponds to the tube delivery mode specified in the manufacturer's ordering information. Ensure thermal management requirements align with the derating curves provided in the datasheet for the intended operating environment.

Bridge Rectifier Selection Notes

Select this component based on the required reverse voltage blocking capability and the available thermal dissipation path. The average forward current rating varies significantly between heatsink mounting and bare PCB mounting configurations. Designers must account for the thermal resistance values to ensure the junction temperature remains within the specified operational limits under continuous load conditions.

Bridge Rectifier Part Context

This part belongs to the VSIB2520 through VSIB2580 series of single-phase single in-line bridge rectifiers. The series offers varying reverse voltage ratings from 200 V to 800 V while maintaining a consistent 25 A average forward current rating and GSIB-5S package style. The VSIB2580 variant specifically addresses applications requiring higher voltage isolation capabilities within the same physical footprint.

Bridge Rectifier Replacement Considerations

Direct replacement options include other parts within the VSIB25 series such as VSIB2560-E3/45 or VSIB2540-E3/45 if lower voltage ratings are acceptable. Verify that any substitute maintains the GSIB-5S case style and matches the electrical characteristics for the specific circuit requirements.
