GSIB2580-5401E3/45

Overview

The GSIB2580-5401E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward rectified current (IF(AV)) of 25 A and supports peak repetitive reverse voltages (VRRM) ranging from 200 V to 800 V. The device has a maximum surge forward current (IFSM) of 350 A and a low reverse leakage current of 10 µA at rated voltage. With a typical forward voltage drop (VF) of 1.0 V, it operates within a junction temperature range of -65°C to 150°C. The component utilizes the GSIB-5S case style for through-hole mounting.

Feature Summary

• High current handling capability with 25 A average forward rectified current rating
• Wide voltage selection available across 200 V to 800 V peak reverse voltage options
• Robust surge protection with 350 A non-repetitive peak forward surge current capacity
• Low thermal resistance design supporting high junction temperatures up to 150°C

Applications

• Industrial power supply units requiring high current rectification
• DC motor drive systems and variable frequency drives
• Battery charging equipment for automotive or industrial applications
• General-purpose AC to DC conversion in heavy-duty electronics

Procurement Notes

Verify the specific voltage variant required, as the base series covers 200 V to 800 V. Confirm the suffix matches the exact electrical specification needed. Check RoHS compliance status if environmental regulations apply. Ensure the GSIB-5S package dimensions fit the target PCB layout. Validate authenticity through authorized distribution channels due to potential counterfeits in high-power components.

Selection Notes

Select based on the maximum reverse voltage present in the AC input line, adding appropriate safety margins. Consider the ambient temperature and cooling method when evaluating the 25 A continuous current rating. Compare forward voltage drop characteristics against efficiency requirements. Verify that the 350 A surge rating exceeds the expected inrush currents of the load. Ensure the operating temperature range aligns with the application environment.

Part Context

This component belongs to the GSIB series of single-phase bridge rectifiers designed for high-current applications. The GSIB-5S package provides a compact footprint relative to its power handling capabilities. Vishay's manufacturing process ensures consistent performance across the voltage range. The E3 suffix indicates lead-free construction compliant with international standards.

Replacement Considerations

Direct replacements must match the 25 A current rating and compatible voltage class. Alternative packages like GBPC may require mechanical adaptation. Verify that substitute devices offer equal or better surge current ratings. Check for equivalent thermal performance to maintain system reliability. Ensure pinout compatibility if direct board replacement is intended.
