GBU8M-BP

Overview

The GBU8M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It utilizes glass passivation for the cathode mark identification and is housed in a GBU surface-mount package. The device is designed for general-purpose rectification applications requiring high reliability. Key electrical specifications include an average forward rectified current of 8A, a maximum repetitive peak reverse voltage of 1000V, and a non-repetitive peak forward surge current capability of 200A under specified conditions.

Feature Summary

• Glass passivated cathode marks provide enhanced mechanical strength and improved resistance to moisture damage compared to standard plastic encapsulated devices.
• Utilizes molded plastic technique for reliable low-cost construction with Underwriters Laboratory flammability classification 94V-0.
• Designed for printed circuit board mounting with terminals that are solderable per MIL-STD-208 Method 208.

Applications

• General purpose rectification in AC to DC power supply circuits.
• Bridge rectifier configurations in industrial control systems.
• Power supply units for consumer electronics and appliances.

Procurement Notes

Verify the specific suffix and marking on the component body to confirm it matches the GBU8M-BP designation from Micro Commercial Components. Ensure the datasheet revision aligns with the required regulatory compliance standards such as RoHS if applicable to the end product. Cross-reference the manufacturer part number against official MCC catalogs to avoid counterfeit components.

Selection Notes

Select this component when a surface-mount bridge rectifier with 8A continuous current and 1000V reverse voltage rating is required. Consider the GBU package dimensions for PCB layout constraints. Evaluate thermal management requirements based on the expected forward voltage drop and ambient operating temperature range specified in the official datasheet.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50V to 1000V while maintaining a consistent 8A current capacity and standardized GBU footprint. This allows for design flexibility across different voltage requirements without changing the physical board layout.

Replacement Considerations

Compatible replacements must match the 8A current rating, 1000V reverse voltage, and GBU surface-mount package. Verify pinout compatibility and thermal characteristics before substitution. Other manufacturers offering equivalent GBU-series bridge rectifiers with similar electrical parameters may serve as functional alternatives.
