KBU4J-M3/P

Overview

The KBU4J-M3/P is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes standard silicon technology and features a KBU-4 through-hole package. The device supports an average forward current of 4 A and withstands a maximum repetitive peak reverse voltage of 600 V. Key electrical characteristics include a forward voltage of 1 V at the rated current, a reverse leakage current of 5 µA at 600 V, and a non-repetitive peak forward surge current capability of 200 A. It operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• Glass passivated junction construction for enhanced environmental stability
• High thermal performance suitable for demanding power applications
• Isolated case design for simplified mounting and safety

Applications

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

Procurement Notes

Verify the specific suffix 'P' against official datasheets to confirm packaging details, as suffixes may indicate variations in reel or tube specifications without altering electrical function. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability. Confirm RoHS compliance status via the latest product change notification documents provided by Vishay.

Selection Notes

Select this component when a 600 V rating is required for single-phase bridge rectification with a 4 A continuous load. Ensure the application environment stays within the specified -50°C to +150°C junction temperature range. Verify that the PCB layout accommodates the KBU-4 through-hole footprint and provides adequate clearance for the isolated case connection.

Part Context

This component belongs to the KBU series of bridge rectifiers from Vishay, designed for general-purpose power conversion. The series offers various voltage ratings while maintaining a consistent 4 A current capacity and standardized KBU package form factor. This specific variant targets applications requiring higher voltage blocking capabilities compared to lower-rated siblings in the same family.

Replacement Considerations

KBU4J-M3/A is a parameter-equivalent alternative from the same manufacturer. Verify pinout compatibility and package dimensions before substitution. Other manufacturers offering 4 A, 600 V bridge rectifiers in the KBU-4 package may serve as functional replacements if electrical parameters meet or exceed original specifications.
