KBU8A-M3/P

Overview

The KBU8A-M3/P is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average rectified output current of 8 A and a maximum repetitive peak reverse voltage of 50 V. The device utilizes standard silicon technology with a forward voltage of 980 mV at 8 A and a reverse leakage current of 10 µA at 50 V. Designed for through-hole mounting in the 4-SIP KBU package, it operates within a junction temperature range of -50°C to 150°C.

Feature Summary

• Glass passivated junctions provide mechanical stability and resistance to soldering conditions.

Applications

• Power supply circuits requiring low voltage AC to DC conversion

Procurement Notes

Verify the specific suffix P against the required packaging format, as the M3/A variant typically uses bulk packaging while the P suffix indicates tube packaging. Confirm RoHS compliance status via the official datasheet before finalizing procurement specifications for assembly lines.

Selection Notes

Select this component when a 50 V rating is sufficient for the application, offering lower forward voltage drop compared to higher voltage variants. Ensure the PCB layout accommodates the KBU through-hole footprint and provides adequate thermal management for 8 A continuous operation.

Part Context

This part belongs to the KBU series of bridge rectifiers from Vishay, designed for general-purpose power applications. The M3 designation indicates lead-free termination and halogen-free molding compound, aligning with modern environmental standards for electronic components.

Replacement Considerations

The KBU8A-M3/A is a parameter-equivalent alternative available from the same manufacturer. Verify that the packaging difference does not impact automated placement equipment compatibility before substituting.
