KBU6A-M3/P

Overview

The KBU6A-M3/P is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward rectified current (Io) of 6 A and a maximum repetitive peak reverse voltage (Vrrm) of 50 V. The device utilizes a standard silicon junction technology with a forward voltage (Vf) of 1.1 V at 6 A. It operates within a junction temperature range of -50°C to +150°C and has a non-repetitive peak forward surge current capability of 200 A. The component is housed in a plastic KBU package designed for through-hole mounting.

Feature Summary

• Glass-passivated junction for enhanced environmental stability
• Plastic case rated for UL flame resistance classification 94V-0
• Molded epoxy complies with flammability standards

Applications

• AC-to-DC power supply circuits
• Battery charging systems
• General-purpose rectification in low-voltage electronics

Procurement Notes

Verify the specific suffix 'P' indicates tube packaging when reviewing distributor listings, as 'A' typically denotes bulk. Confirm RoHS compliance status via the official datasheet, as M3 suffixes generally indicate lead-free construction. Cross-reference the manufacturer part number against the distributor's unique ID to ensure accurate sourcing of the Vishay component.

Selection Notes

Select this component for applications requiring 6 A continuous current at 50 V reverse voltage. Ensure the PCB layout accommodates the KBU through-hole footprint dimensions. Verify that the thermal management strategy supports the specified junction temperature limits under expected load conditions. Compare Vf characteristics against alternative rectifiers if voltage drop efficiency is critical.

Part Context

This part belongs to the KBU series of glass-passivated bridge rectifiers from Vishay. The series offers various current ratings and voltage options within the same KBU plastic housing. The M3 suffix designates the lead-free and halogen-free compliant version of the component, aligning with modern environmental directives for electronic assemblies.

Replacement Considerations

Direct parameter-equivalent substitutes include the KBU6A-M3/A variant from the same manufacturer. Other manufacturers offering similar KBU-form factor rectifiers with matching 6 A/50 V specifications may serve as functional replacements, provided pinout and thermal characteristics are verified.
