GBU4G-BP

Overview

The GBU4G-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 400 V peak reverse voltage and supports a continuous forward current of 4 A. The device utilizes a glass-passivated chip junction for enhanced reliability and surge overload capability. Designed for surface-mount installation, it is housed in a GBU package with solder pad termination. Key electrical parameters include a maximum forward voltage of 1 V, a reverse leakage current of 5 uA, and a peak non-repetitive surge current rating of 150 A. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Glass-passivated chip junction provides high reliability and surge overload ratings
• Surface-mount GBU package design facilitates automated PCB assembly
• RoHS compliant construction with lead-free finish

Applications

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

Procurement Notes

Verify the procurement status carefully as the GBU4G-BP is designated as NRND (Not Recommended for New Designs). This classification indicates that the manufacturer does not recommend its inclusion in new products, although existing stock may remain available through distributors. Confirm availability and potential obsolescence risks before finalizing component selection for production.

Selection Notes

Select this component when a 4 A single-phase bridge rectifier with a 400 V reverse voltage rating is required for surface-mount applications. Ensure the design accommodates the specific thermal characteristics and physical dimensions of the GBU package. Verify that the operating environment remains within the specified -55 °C to +150 °C temperature range for optimal performance.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings, including 200 V, 400 V, 600 V, and 800 V options, all sharing similar mechanical footprints. The GBU4G-BP specifically addresses applications requiring moderate current handling and standard voltage isolation in compact surface-mount form factors.

Replacement Considerations

Cross-reference with other MCC GBU series variants such as GBU4D-BP or GBU4M-BP if different voltage ratings are acceptable. Verify pinout compatibility and thermal requirements when substituting with components from other manufacturers offering equivalent GBU-style packages.
