GBU3002-BP

Overview

The GBU3002-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 30 Amp average rectified forward current and a 200 Volt peak repetitive reverse voltage rating. The device utilizes glass passivated chip junctions for high reliability and surge current capability. Encased in a plastic GBU package, it meets UL 94 V-0 flammability standards and is RoHS compliant with lead-free finishes. Thermal resistance from junction to case is 1 °C/W, supporting operation up to 150°C.

Feature Summary

• Glass passivated chip junction provides high reliability and efficient performance under varying thermal conditions.
• High surge forward current capability ensures robust handling of transient electrical loads during circuit startup or fault events.
• Epoxy encapsulation meets UL 94 V-0 flammability ratings, offering enhanced safety and durability in electronic assemblies.

Applications

• General-purpose AC to DC power supply conversion circuits
• Battery charging systems requiring moderate current handling
• Industrial control equipment power stages

Procurement Notes

Verify authenticity by purchasing exclusively from MCC or authorized distributors due to industry counterfeiting risks. Confirm the "BP" suffix indicates RoHS compliance and lead-free construction. Ensure storage conditions align with moisture sensitivity level requirements before soldering to maintain component integrity and prevent package damage during assembly.

Selection Notes

Select this component when a 30A continuous current and 200V blocking voltage are required in a through-hole configuration. Evaluate thermal management needs based on the 22 °C/W junction-to-ambient resistance if heatsinking is not utilized. Compare against other GBU series variants to ensure the specific voltage rating matches the circuit's peak reverse voltage demands without excessive derating.

Part Context

This part belongs to the GBU30005 through GBU3010 series, which shares identical mechanical dimensions and thermal characteristics across different voltage ratings. The series offers standardized mounting and footprint compatibility, allowing designers to swap voltage ratings within the same physical package while maintaining consistent board layout constraints and assembly processes.

Replacement Considerations

Direct substitutes include other GBU3002 models from different manufacturers that match the 30A/200V specifications and GBU package outline. Verify pinout orientation and forward voltage drop characteristics to ensure circuit compatibility. Cross-reference datasheets for equivalent thermal resistance and surge current capabilities before implementation.
