GSIB2040-E3/45

Overview

The GSIB2040-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 20 A at a case temperature of 87 °C. The device exhibits a maximum instantaneous forward voltage drop of 1.0 V at 10 A and a maximum DC reverse current of 10 µA at 25 °C. It provides a peak forward surge current capability of 240 A and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge current capability with 240 A peak rating
• Thin single in-line package design for compact mounting
• High case dielectric strength rated at 2500 V RMS

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Rectification circuits in home appliances
• Power stages in office equipment
• Industrial automation applications

Procurement Notes

Verify component authenticity by checking the manufacturer's marking on the GSIB-5S package against official datasheet specifications. Confirm RoHS compliance via the E3 suffix and ensure the ordering code matches the specific voltage variant required for the target circuit design.

Selection Notes

Select this component when a 400 V blocking voltage and 20 A continuous current are required in a low-profile through-hole form factor. Ensure adequate thermal management is provided, as the 20 A rating is specified at a case temperature of 87 °C rather than ambient conditions.

Part Context

This part belongs to the GSIB20xx series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings (200 V, 600 V, 800 V) sharing the same GSIB-5S mechanical footprint and electrical characteristics regarding current handling and thermal performance.

Replacement Considerations

Direct substitutes include other Vishay parts within the same series such as GSIB2020-E3/45, GSIB2060-E3/45, or GSIB2080-E3/45, which share identical packaging and current capabilities but differ in reverse voltage ratings.
