GBU4M-E3/51

Overview

The GBU4M-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage (Vrrm) of 1000 V and an average forward rectified current (Io) of 4 A. The device supports a non-repetitive peak forward surge current (Ifsm) of 150 A. It utilizes the GBU surface-mount package with solder pad termination. The junction temperature range extends from -55°C to +150°C, ensuring reliable operation in demanding thermal environments.

Feature Summary

• High-voltage capability with 1000 V reverse voltage rating for robust power conversion
• Surface-mount GBU package design facilitates automated assembly and compact board layout
• Lead-free construction compliant with environmental directives

Applications

• General-purpose AC-DC power supply circuits
• Battery charging systems requiring high reverse voltage isolation
• Industrial control modules utilizing surface-mount topology

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official datasheets. Validate package dimensions against PCB footprint requirements prior to integration. Ensure storage conditions maintain junction integrity within specified temperature limits.

Selection Notes

Select this component when 1000 V reverse blocking capability is required in a surface-mount form factor. Compare Ifsm ratings against transient load profiles. Verify thermal management strategies align with the 150°C maximum junction temperature specification for long-term reliability.

Part Context

This part belongs to the Vishay GBU4 series of single-phase bridge rectifiers. The suffix E3 indicates lead-free plating. The /51 designation typically refers to specific tape-and-reel packaging configurations offered by distributors. It serves as a standard solution for medium-power rectification tasks in modern electronics manufacturing.

Replacement Considerations

Direct substitutes include other Vishay GBU4 series variants such as GBU4J-E3/51 or GBU4K-E3/51, which share identical mechanical footprints but differ in voltage ratings. Cross-manufacturer replacements require verification of pinout compatibility and thermal characteristics.
