GBU3004-BP

Overview

The GBU3004-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 30 A at 25°C and a peak repetitive reverse voltage of 400 V. The device utilizes glass-passivated chip junctions and epoxy meeting UL 94 V-0 flammability ratings. Electrical characteristics include a maximum forward voltage of 1.0 V, a non-repetitive peak surge current of 350 A for an 8.3 ms half-sine wave, and a reverse leakage current of 5 µA at 25°C. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junctions provide reliable operation under standard conditions.
• High surge forward current capability supports transient load handling.
• Epoxy material meets UL 94 V-0 flammability rating standards.

Applications

• AC to DC power supply conversion circuits
• Battery charging systems
• General purpose rectification in electronic equipment

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer. Counterfeit components are prevalent; unauthorized sources lack traceability and warranty coverage. Confirm RoHS compliance via the "BP" suffix designation. Ensure procurement channels align with MCC's quality standards for handling and storage to maintain component integrity.

Selection Notes

Select this component based on the 400 V peak repetitive reverse voltage requirement and 30 A average forward current capacity. Consider thermal management needs, as the rated current applies at 25°C without a heatsink. Verify that the GBU package dimensions fit the target PCB layout. Evaluate the 1.0 V forward voltage drop against system efficiency targets.

Part Context

This part belongs to the GBU3000 series, which offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 30 A current rating. The GBU3004 specifically designates the 400 V variant within this family. All members share identical mechanical dimensions and thermal characteristics, allowing for pin-compatible design flexibility across different voltage requirements.

Replacement Considerations

Cross-reference other manufacturers' GBU-series bridge rectifiers with matching 30 A and 400 V specifications. Verify that substitute parts meet the same forward voltage, reverse leakage, and thermal resistance parameters. Ensure the replacement maintains the required UL 94 V-0 flammability rating and physical footprint compatibility.
