GSIB2080-E3/45

Overview

The GSIB2080-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes glass passivated chip junctions and is housed in a thin single-in-line GSIB-5S package. The device supports a maximum repetitive peak reverse voltage of 800 V and an average forward rectified output current of 20 A at a case temperature of 87 °C, or 3.5 A at an ambient temperature of 25 °C without a heatsink. It features a peak forward surge current capability of 240 A for a single sine wave superimposed on rated load. The maximum instantaneous forward voltage drop is 1.00 V at 10 A, with a maximum DC reverse current of 10 μA at 25 °C. The operating junction and storage temperature range spans from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction construction
• High surge current capability
• High case dielectric strength of 2500 V RMS
• Thin single in-line package design

Applications

• AC/DC bridge full wave rectification for switching power supplies
• Home appliances
• Office equipment
• Industrial automation applications

Procurement Notes

Verify the component against official Vishay datasheet document number 88645 to confirm technical specifications and compliance status. Ensure that the ordering suffix matches the required RoHS-compliant commercial grade configuration. Confirm the physical package style and terminal plating details align with the intended PCB mounting requirements before finalizing procurement.

Selection Notes

Select this component based on the specific reverse voltage requirement of 800 V and the necessary forward current capacity. Evaluate thermal management needs carefully, as the average forward current drops significantly from 20 A to 3.5 A when transitioning from heatsink-mounted to PCB-only mounting conditions. Verify that the application environment stays within the specified -55 °C to +150 °C operating temperature range.

Part Context

This part belongs to the GSIB20xx series of single-phase single in-line bridge rectifiers from Vishay. The series includes variants with different voltage ratings: GSIB2020 (200 V), GSIB2040 (400 V), GSIB2060 (600 V), and GSIB2080 (800 V). All models share identical physical dimensions, current ratings, and package styles, differing only in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

Direct replacement options within the same series include GSIB2020-E3/45, GSIB2040-E3/45, and GSIB2060-E3/45. These alternatives offer lower voltage ratings but maintain the same 20 A current rating and GSIB-5S package. Ensure the substitute part's voltage rating meets or exceeds the circuit's peak reverse voltage requirements.
