GBU4A-BP

Overview

The GBU4A-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current rating of 4 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes a glass-passivated silicon junction for high reliability and surge overload capability. It is housed in a GBU surface-mount package with solder pad termination, measuring 22.3 mm in length, 3.56 mm in width, and 18.8 mm in height. Key electrical parameters include a maximum forward voltage drop of 1 V at rated current, a non-repetitive peak forward surge current of 150 A, and a maximum reverse leakage current of 5 µA. 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 low-voltage electronics

Procurement Notes

Verify the NRND status before integration, as this designation indicates the component is not recommended for new designs. Confirm RoHS compliance requirements against specific project standards. Ensure the GBU footprint matches the target PCB layout dimensions precisely. Validate thermal management capabilities given the SMD package constraints.

Selection Notes

Select this component for applications requiring 4 A continuous current and 50 V blocking voltage in a compact surface-mount form factor. Compare alternative voltages within the GBU4 series if higher reverse voltage tolerance is necessary. Consider through-hole variants if mechanical stress resistance is critical for the installation environment.

Part Context

This part belongs to the GBU4A series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings while maintaining consistent current handling and physical dimensions. The 'BP' suffix specifically denotes RoHS compliance and lead-free manufacturing attributes.

Replacement Considerations

Direct substitutes may include other GBU4A variants from different manufacturers offering identical 4 A/50 V specifications. Verify pinout compatibility and thermal characteristics when cross-referencing with equivalent parts from other suppliers.
