GBU4K-BP

Overview

The GBU4K-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 400V peak repetitive reverse voltage and supports an average forward rectified current of 4A. The device utilizes a glass-passivated chip junction for reliability and is housed in a GBU surface-mount package with solder pad termination. Key electrical parameters include a maximum forward voltage of 1V, a reverse leakage current of 5µA, and a surge current rating of 150A. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass-passivated chip junction construction ensures high reliability and stable performance under varying thermal conditions.
• Molded plastic case material provides mechanical protection with UL flammability classification rating 94V-0.
• Designed for surface-mount installation using solder pads, facilitating automated PCB assembly processes.

Applications

• General-purpose AC to DC power supply circuits requiring compact rectification.
• Battery charging systems utilizing surface-mount technology.
• DC power adapters and consumer electronic power stages.

Procurement Notes

Verify the specific suffix 'BP' confirms RoHS compliance and lead-free finish as per manufacturer specifications. Confirm availability status, as this component may be classified as Not Recommended for New Designs (NRND) in certain distributor catalogs. Ensure the ordering quantity matches the bulk packaging requirements specified in the official datasheet.

Selection Notes

Select the GBU4K-BP when a 400V reverse voltage rating is required for 4A applications. Compare against other GBU series variants if higher voltage or current ratings are needed. Verify that the GBU package dimensions fit the target PCB footprint. Consider the operating temperature range limits for high-heat environments.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings (e.g., GBU4A through GBU4M) while maintaining consistent current handling and package form factors. The GBU4K specifically denotes the 400V variant within this standardized lineup.

Replacement Considerations

Direct substitutes include other GBU4K part numbers from different manufacturers such as Fairchild Semiconductor's GBU4K. Cross-reference pinouts and thermal characteristics before substitution. Note that generic equivalents must match the 4A/400V specification and GBU package outline.
