GBU6K-M3/51

Overview

The GBU6K-M3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It utilizes silicon diode elements housed in a plastic GBU case with four pins. The device supports an average forward current of 6 A and offers a maximum repetitive peak reverse voltage of 700 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200 A, a reverse leakage current of 5 µA, and a maximum junction temperature of 150 °C. The component complies with RoHS standards and features isolated case connection.

Feature Summary

• High surge current capability for robust transient protection
• Isolated case design for enhanced safety and mounting flexibility
• Compliant with UL flammability standards

Applications

• Printed circuit board assembly for power supplies
• General-purpose AC to DC conversion circuits
• Industrial control systems requiring reliable rectification

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm terminal plating and compliance status. Ensure the ordering code matches the required voltage rating and package type. Cross-reference datasheet revisions to confirm material composition and regulatory certifications before finalizing procurement specifications.

Selection Notes

Select this component based on the 6 A current requirement and 700 V reverse voltage rating. Confirm that the GBU surface-mount package fits the PCB layout constraints. Verify thermal management requirements align with the 150 °C maximum junction temperature specification under expected operating conditions.

Part Context

This part belongs to the Vishay GBU series of single-phase bridge rectifiers. The series provides various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 6 A average forward current rating. The GBU package is designed for surface-mount applications, offering high reliability and mechanical stability compared to through-hole alternatives.

Replacement Considerations

Compatible substitutes within the same family include GBU6J-E3/51 (600 V) and GBU6M-E3/51 (1000 V). Ensure the replacement maintains the 6 A current rating and compatible GBU footprint. Verify that the reverse voltage rating of the substitute meets or exceeds the original circuit requirements.
