GBU1004H

Overview

The GBU1004H is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a 400 V maximum repetitive peak reverse voltage and supports an average forward rectified current of 10 A. The device utilizes a glass passivated chip junction for enhanced reliability and operates within a junction temperature range of -55°C to 150°C. It is housed in a through-hole GBU (4-ESIP) package, which provides an isolated case connection. The component meets AEC-Q101 automotive qualification standards and complies with RoHS3 directives.

Feature Summary

• Glass passivated chip junction ensures high reliability and stable performance under varying conditions.
• Automotive-grade qualification aligns with AEC-Q101 standards for rigorous quality requirements.
• Isolated case design facilitates efficient thermal management and mounting flexibility.

Applications

• Automotive power supply circuits requiring robust rectification.
• Industrial equipment utilizing standard bridge rectifier configurations.
• General-purpose AC to DC conversion in consumer electronics.

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm packaging details, as suffixes may indicate variations in tube or reel quantities. Ensure compliance with REACH and RoHS3 regulations for the intended market. Confirm that the GBU package dimensions match the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a 10 A current rating and 400 V reverse voltage are required for single-phase applications. The GBU package is suitable for through-hole mounting where higher current capacity is needed compared to smaller surface-mount options. Consider the 1.1 V forward voltage drop at 10 A for thermal design calculations to ensure adequate heat dissipation.

Part Context

This part belongs to the GBU1001–GBU1007 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining a consistent 10 A current capability and GBU package form factor. The 'H' suffix typically denotes specific packaging or environmental compliance attributes within this product line.

Replacement Considerations

Direct substitutes include other GBU1004 variants from different manufacturers offering identical 10 A/400V specifications in the GBU package. Verify pinout compatibility and thermal resistance values when considering alternatives from other suppliers to ensure seamless integration.
