GBUA6M-BP

Overview

The GBUA6M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 6 A and a peak repetitive reverse voltage of 1000 V. The device utilizes a GBU surface-mount package with solder pad termination, designed for automated PCB assembly. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current and a non-repetitive peak surge current capacity of 230 A. The component operates within a junction temperature range of -55 °C to +150 °C, with a typical reverse leakage current of 5 µA.

Feature Summary

• High thermal stability supporting operation up to +150 °C junction temperature
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved power efficiency
• Surface-mount GBU package optimized for high-volume automated placement

Applications

• AC-DC converter circuits in consumer electronics
• Power supply units requiring compact bridge rectification
• General-purpose rectification in industrial control systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Micro Commercial Components or authorized distributors before integration. Confirm that the GBU footprint matches your PCB design guidelines. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.

Selection Notes

Select this component when a 6 A continuous current rating and 1000 V blocking voltage are required in a surface-mount form factor. Compare the 1.1 V forward voltage against alternative packages if thermal dissipation is critical. Verify that the 230 A surge rating exceeds the inrush current specifications of the target application circuit.

Part Context

This part belongs to the MCC GBU series of glass-passivated silicon bridge rectifiers. The 'A' suffix typically denotes the GBU surface-mount package variant, while 'M' indicates the 1000 V voltage rating. It serves as a surface-mount alternative to through-hole GBJ or GBU series components, offering similar electrical performance in a compact footprint suitable for modern PCB layouts.

Replacement Considerations

Direct pin-compatible replacements may include other manufacturers' GBU-series 6A 1000V bridge rectifiers such as those from Diodes Incorporated or Vishay. Verify that substitute parts meet the same 1.1 V max forward voltage and 230 A surge current specifications to ensure circuit compatibility.
