KBU6G-M3/A

Overview

The KBU6G-M3/A is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 600 V maximum repetitive peak reverse voltage and supports an average forward rectified current of 6 A. The device utilizes a standard silicon junction technology with a forward voltage drop of 1.1 V at the rated current. It is housed in a KBU (4-SIP) through-hole package, designed for high thermal performance and mechanical robustness. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• High surge current capability for reliable operation under transient conditions
• Low forward voltage drop for improved efficiency
• Molded plastic case provides protection against mechanical shock and vibration

Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm marking and packaging details. Ensure the ordering part number matches the required voltage and current ratings for the target application. Cross-reference with authorized distributors to confirm current availability and lead times, as stock levels fluctuate.

Selection Notes

Select this component when a 600 V rating is required for mains frequency rectification. The 6 A continuous current rating suits moderate power applications. Verify that the PCB footprint accommodates the KBU SIP package dimensions. Consider thermal management requirements based on the expected ambient temperature and load profile.

Part Context

This part belongs to Vishay's KBU series of bridge rectifiers, which are widely used in general-purpose electronics. The M3 suffix indicates Halogen-free and RoHS compliance. The KBU package offers a compact solution for through-hole mounting, balancing current capacity with board space constraints in standard power supplies.

Replacement Considerations

Direct pin-compatible replacements from other manufacturers must match the 6 A current, 600 V voltage, and KBU package type. Verify forward voltage and leakage current specifications to ensure equivalent performance. Check for any differences in surge current ratings or thermal resistance values.
