GSIB1540-E3/45

Overview

The GSIB1540-E3/45 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 15 A at a case temperature of 107 °C. The device exhibits a maximum instantaneous forward voltage drop of 0.95 V at 7.5 A and a peak forward surge current capability of 300 A. Operating junction temperatures range from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge current capability with 300 A rating
• Thin single in-line package design for compact mounting
• High case dielectric strength of 2500 V RMS

Applications

• AC/DC bridge full wave rectification for switching power supplies

Procurement Notes

Verify component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm RoHS compliance status via the E3 suffix designation. Ensure the ordering code matches the specific voltage rating required for the target circuit application before finalizing procurement.

Selection Notes

Select this component when a 400 V blocking voltage and 15 A continuous current are required in a low-profile through-hole configuration. Evaluate thermal management requirements based on the specified thermal resistance values. Verify that the operating environment remains within the -55 °C to +150 °C junction temperature limits.

Part Context

This part belongs to the GSIB15xx series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings such as 200 V, 600 V, and 800 V, all sharing the same GSIB-5S mechanical footprint and similar electrical characteristics.

Replacement Considerations

Direct substitutes include other Vishay parts within the GSIB15xx series with matching or higher voltage ratings, such as GSIB1520-E3/45 or GSIB1560-E3/45. Cross-manufacturer replacements must match the 15 A current rating, 400 V minimum reverse voltage, and GSIB-5S package dimensions.
