GBU6M-BP

Overview

The GBU6M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 6 A. The device utilizes glass passivated chip junctions for enhanced reliability. Key electrical parameters include a maximum non-repetitive surge current of 175 A at 8.3 ms, a maximum DC blocking reverse current of 5 µA at rated voltage, and a maximum RMS isolation voltage of 400 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junctions ensure stable operation and long-term reliability under varying thermal conditions.
• High surge current capability provides robust protection against transient overcurrent events during power-up or fault conditions.
• Designed for surface mount applications with a plastic package rated for flammability UL 94 V-0.

Applications

• General-purpose AC to DC conversion in low to medium power supply circuits.
• Battery charging systems requiring high reverse voltage tolerance.
• Inverter circuits and motor drive power stages.

Procurement Notes

Verify the specific suffix and marking code on the physical component to confirm it matches the GBU6M-BP designation exactly. Check the manufacturer's latest datasheet for any updates regarding RoHS compliance status and lead time requirements. Confirm that the supplier provides traceable documentation for the batch lot number to ensure quality assurance standards are met for your specific application environment.

Selection Notes

Select this component when a 1000 V reverse voltage rating is required for bridge rectification. Ensure the PCB layout supports the GBU package dimensions and solder pad configuration. Verify that the expected load current remains below the 6 A average forward current limit and that thermal management strategies account for the forward voltage drop at maximum operating temperatures.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50 V to 1000 V, all sharing the same 6 A current capacity and mechanical footprint. The GBU6M-BP specifically addresses applications needing the highest standard voltage rating in this common package style.

Replacement Considerations

Direct replacements must match the 6 A current rating, 1000 V reverse voltage, and GBU package type. Verify pinout compatibility and thermal characteristics before substitution.
