KBU4A-M3/P

Overview

The KBU4A-M3/P is a single-phase standard bridge rectifier manufactured by Vishay General Semiconductor. It features a peak reverse voltage of 50 V and an average rectified current of 4 A. The forward voltage drop is specified as 950 mV at 4 A, with a maximum reverse leakage current of 10 µA at 50 V. Designed for through-hole mounting in the KBU package, it operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Single-phase full-wave rectification using standard technology
• Through-hole KBU package construction
• RoHS compliant M3 suffix designation

Applications

• General purpose AC to DC power supply conversion
• Battery charging circuits
• Low voltage DC power adapters

Procurement Notes

Verify the specific suffix P against the manufacturer's official datasheet to confirm packaging details and lead time requirements. Ensure the component meets RoHS standards if required by the design specification. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring 4 A continuous current and 50 V blocking capability. The KBU package is suitable for through-hole PCB assembly where space allows. Consider thermal management requirements based on the forward voltage drop and ambient operating conditions to ensure reliable performance within the specified temperature range.

Part Context

This device belongs to the KBU series of bridge rectifiers from Vishay Diodes Division. The series offers various voltage ratings while maintaining a consistent 4 A current capacity and standardized mechanical footprint. The M3 suffix indicates compliance with specific environmental directives, distinguishing it from commercial grade variants.

Replacement Considerations

KBU4A-M3/A is a parameter-equivalent alternative from the same manufacturer.
