GBU6G-M3/51

Overview

The GBU6G-M3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features glass passivated junctions and is housed in a GBU surface-mount package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 6 A. Key electrical parameters include a maximum non-repetitive surge current of 200 A, a typical forward voltage drop of 1.1 V at rated current, and a maximum reverse leakage current of 5 µA at 400 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated junctions provide enhanced stability and reliability under various operating conditions.
• Surface mount GBU package design facilitates automated assembly and efficient PCB space utilization.
• High surge current capability ensures robust performance during transient overload events.

Applications

• AC-DC power supply circuits requiring surface mount bridge rectification.
• General purpose rectification in consumer electronics and industrial equipment.
• Battery charging systems utilizing low-voltage AC inputs.

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm pinout compatibility and packaging format. Ensure that the ordering code matches the required voltage rating and current capacity for the target application. Cross-reference datasheets to validate thermal resistance values and mounting requirements before finalizing procurement specifications.

Selection Notes

Select this component when a 6 A surface mount bridge rectifier with a 400 V reverse voltage rating is required. Compare forward voltage drop characteristics against alternative packages to ensure thermal management meets system constraints. Verify that the GBU footprint aligns with existing PCB layout designs and soldering profiles.

Part Context

This part belongs to Vishay's SUPERECTIFIER series, which focuses on high-reliability surface mount diodes. The GBU series offers a compact form factor compared to through-hole alternatives while maintaining comparable current handling capabilities. The M3 suffix typically indicates lead-free composition compliant with RoHS directives.

Replacement Considerations

Direct substitutes include the GBU6G-E3/51 variant, which shares identical electrical specifications and mechanical dimensions. Other compatible options from different manufacturers must match the 6 A current rating, 400 V reverse voltage, and GBU package outline to ensure physical and functional interchangeability.
