GBU8G-E3/51

Overview

The GBU8G-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the GBL package configuration and supports through-hole mounting. The device features a peak repetitive reverse voltage (Vrrm) of 800V and a maximum average forward rectified current (If) of 4A. It exhibits a peak non-repetitive forward surge current (Ifsm) rating of 200A. The component operates within a junction temperature range of -55°C to +150°C, with a specified peak forward voltage drop of 1V and a peak reverse leakage current of 5μA.

Feature Summary

• High-voltage capability suitable for demanding power supply applications
• Robust surge current handling for transient protection
• Extended thermal operating range for high-temperature environments

Applications

• General-purpose AC to DC conversion circuits
• Power supply units requiring high reverse voltage isolation
• Industrial control systems with significant inductive loads

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and compliance status. Ensure the ordering part number matches the required voltage and current ratings for the target design. Confirm availability through authorized distributors as manufacturing schedules may vary. Cross-reference datasheet revisions to ensure compatibility with existing assembly processes.

Selection Notes

Select this component when an 800V reverse voltage rating is necessary for the circuit design. The 4A continuous current capacity suits moderate power applications. Verify that the GBL package dimensions fit the PCB layout constraints. Consider the 150°C maximum junction temperature for thermal management calculations in enclosed spaces.

Part Context

This component belongs to the GBU series of bridge rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent mechanical packaging. The GBU8G variant specifically addresses higher voltage requirements compared to lower-rated siblings in the same physical footprint family.

Replacement Considerations

Direct substitutes include other Vishay GBU8 variants with matching 800V ratings, such as GBU8J or GBU8H, provided current and package compatibility is confirmed. Third-party equivalents must match the 800V Vrrm, 4A If, and GBL package specifications exactly.
