KBU8D-M3/A

Overview

The KBU8D-M3/A is a single-phase standard 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 200 V. The forward voltage drop is specified at 950 mV when conducting 4 A, with a reverse leakage current of 5 µA at the rated voltage. Designed for through-hole mounting in a 4-SIP KBU package, it operates within a junction temperature range of -50°C to 150°C.

Feature Summary

• Glass passivated chip construction ensures high reliability and stability under various operating conditions.

Applications

• General purpose AC-to-DC full-wave bridge rectification
• Switching power supply input stages
• Home appliance power circuits

Procurement Notes

Verify the specific suffix against official datasheets to confirm compliance requirements. Confirm package dimensions and pinout compatibility with existing PCB layouts before finalizing orders. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component for applications requiring 8 A continuous current handling with a 200 V blocking capability. Consider the KBU package size for thermal management needs. Verify that the 950 mV forward voltage drop meets system efficiency targets compared to low-Vf alternatives.

Part Context

This part belongs to the KBU series of glass-passivated single-phase bridge rectifiers. The series offers robust performance for general-purpose rectification tasks. The M3 designation indicates lead-free termination plating compliant with RoHS directives.

Replacement Considerations

KBU8D-M3/P is documented as a parameter-equivalent alternative from the same manufacturer.
