GBUA4M-BP

Overview

The GBUA4M-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 1000 V. The device utilizes a glass-passivated chip junction for reliability and is housed in a GBU surface-mount package. Key electrical specifications include a maximum non-repetitive surge current of 150 A, a forward voltage drop of 1 V, and a 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 construction ensures high reliability and stability under varying thermal conditions.
• Surface-mount GBU package design facilitates automated assembly and efficient PCB layout integration.
• High surge overload capability provides robust protection against transient current spikes during operation.

Applications

• AC-DC power supply circuits requiring compact bridge rectification
• General-purpose rectification in consumer electronics
• Battery charging systems with moderate current requirements

Procurement Notes

Verify the specific suffix 'BP' confirms RoHS compliance and halogen-free status as per manufacturer documentation. Confirm the part number corresponds to the 1000V variant, as the GBU4 series includes multiple voltage ratings. Check for obsolete or NRND status updates from MCC before finalizing procurement plans.

Selection Notes

Select this component when a 4A current rating and 1000V blocking voltage are required in a surface-mount form factor. Ensure the application environment stays within the specified -55°C to +150°C operating range. Compare forward voltage drop characteristics against alternative brands if power loss efficiency is critical.

Part Context

This part belongs to the GBU4 series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50V to 1000V, all sharing the same 4A current rating and GBU package footprint. The 'A' suffix typically denotes the 1000V rating within this specific product line nomenclature.

Replacement Considerations

Direct replacements must match the 4A current, 1000V voltage, and GBU SMD package dimensions. Verify pinout compatibility and thermal performance characteristics. Alternative manufacturers may offer similar specs but require validation of reverse leakage and surge current ratings.
