GBU4B-BP

Overview

The GBU4B-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 4A average forward rectified current rating and a 100V maximum repetitive peak reverse voltage. The device utilizes a glass-passivated chip junction for enhanced reliability and surge overload capability. Designed for surface-mount applications, it is housed in the GBU package with solder pad termination. Key electrical parameters include a maximum forward voltage of 1V, a non-repetitive peak forward surge current of 150A, and a maximum reverse leakage current of 5uA. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction provides high reliability and resistance to thermal stress.
• High surge overload rating supports transient current events during operation.
• Surface-mount design facilitates automated assembly and compact circuit board layouts.

Applications

• General-purpose AC to DC power supply conversion circuits
• Battery charging systems requiring low-voltage rectification
• DC power output stages in consumer electronic devices

Procurement Notes

Verify the NRND status before procurement, as this designation indicates the component is not recommended for new designs. Confirm RoHS compliance via the specific suffix documentation. Ensure the ordering information matches the required voltage and current ratings for the target application to avoid compatibility issues with obsolete inventory sources.

Selection Notes

Select this component when a 100V reverse voltage rating is sufficient for the input AC line. The 4A current capacity suits moderate-power applications. Consider the GBU package dimensions for PCB space constraints. Verify that the 150A surge rating meets the inrush current requirements of the connected load and transformer specifications.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from MCC. The series offers various voltage ratings ranging from 50V to 1000V, identified by suffix letters such as A through M. The GBU4B-BP specifically denotes the 100V variant within this standardized lineup, sharing common mechanical and thermal characteristics with other members of the family.

Replacement Considerations

Direct substitutes must match the 4A current, 100V reverse voltage, and GBU package footprint. Check datasheets for equivalent parts from other manufacturers to ensure pinout compatibility and similar thermal resistance values. Verify that any replacement also carries the necessary safety certifications if used in regulated equipment.
