KBU6K-M3/A

Overview

The KBU6K-M3/A is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak reverse voltage of 1000 V and an average forward rectified current of 6 A. The device exhibits a maximum forward voltage drop of 1.15 V at 6 A and a reverse leakage current of 5 µA at 1000 V. Designed for through-hole mounting in the KBU package, it operates within a junction temperature range of -50°C to 150°C.

Feature Summary

• High surge current capability for robust transient protection
• Plastic material rated for UL flammability classification 94V-0
• Molding compound resistant to mechanical shock

Applications

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

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS compliance status via the latest datasheet revision. Check for any recent product change notices that may affect availability or specifications before finalizing procurement orders.

Selection Notes

Select this component when a 1000 V rating and 6 A continuous current are required in a compact through-hole form factor. Ensure the thermal management design supports the specified junction temperature limits under expected load conditions. Compare with alternative packages if board space constraints differ from the KBU footprint dimensions.

Part Context

This part belongs to the KBU series of bridge rectifiers, which are widely used in general-purpose applications requiring reliable AC-to-DC conversion. The M3 suffix indicates lead-free construction compliant with EU Directive 2002/95/EC on the restriction of hazardous substances. The /A suffix typically denotes specific packaging or marking variations defined by the manufacturer.

Replacement Considerations

Direct substitutes include other Vishay KBU series variants with matching 1000 V and 6 A ratings, such as KBU6G-M3/A or KBU8K-M3/A, provided pin compatibility is verified. Cross-brand replacements must match the KBU package outline and electrical parameters exactly.
