UD6KB40-BP

Bridge Rectifier Overview

The UD6KB40-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivated chip junctions and operates with a maximum repetitive reverse voltage of 400 V. The device supports an average rectified forward current of 6 A at a case temperature of 140°C, with a non-repetitive peak surge current capability of 170 A for an 8.3 ms half sine wave. Electrical characteristics include a typical forward voltage of 1.0 V at 3 A and a maximum reverse leakage current of 5 µA at 25°C. The component utilizes the D3K through-hole package.

Bridge Rectifier Feature Summary

• Glass passivated chip junctions provide reliable operation under varying thermal conditions.
• High surge forward current capability ensures robustness against transient electrical loads.
• Epoxy material meets UL 94 V-0 flammability ratings for enhanced safety compliance.

Bridge Rectifier Applications

• General purpose AC to DC power supply conversion circuits
• Industrial equipment requiring medium voltage rectification
• Consumer electronics power adapters

Bridge Rectifier Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm RoHS compliance via the BP suffix designation. Ensure proper handling and storage protocols are followed to maintain product integrity prior to assembly.

Bridge Rectifier Selection Notes

Select this component when a 400 V peak reverse voltage rating is required alongside a 6 A continuous current capacity. Verify that the operating environment allows for adequate heatsinking to manage thermal resistance, as derating curves indicate reduced current capacity at elevated case temperatures above 140°C.

Bridge Rectifier Part Context

This part belongs to the UD6KB series, which covers voltage ratings from 50 V to 1000 V. All variants in this series share identical physical dimensions and thermal characteristics, differing only in their peak repetitive reverse voltage specifications. The series is designed for general-purpose applications using standard through-hole mounting techniques.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 6 A current rating, 400 V reverse voltage, and D3K package footprint. Verify that alternative manufacturers offer equivalent forward voltage drops and surge current capabilities to ensure circuit compatibility without redesigning the thermal management system.
