UD3KB100-BP

Bridge Rectifier Overview

The UD3KB100-BP is a single-phase bridge rectifier from the UD3KB series manufactured by Micro Commercial Components. It features a glass passivated chip junction and supports peak repetitive reverse voltages up to 1000V with an average rectified forward current of 3A at a case temperature of 140°C. The device exhibits a maximum forward voltage of 1.0V at 1.5A and a reverse leakage current of 10µA at 125°C. It operates within a junction temperature range of -55°C to 150°C and offers a non-repetitive peak surge current capability of 90A for an 8.3ms half-sine wave.

Bridge Rectifier Feature Summary

• Glass passivated chip junction construction
• High surge forward current capability
• Epoxy meets UL 94 V-0 flammability rating
• Lead-free finish and RoHS compliant

Bridge Rectifier Applications

• General purpose AC to DC power supply conversion
• Industrial control systems requiring high voltage isolation
• Consumer electronics power adapters

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm RoHS compliance status via the 'BP' suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Bridge Rectifier Selection Notes

Select this component for applications requiring 1000V reverse blocking capability and 3A continuous current handling. Evaluate thermal management requirements based on the specified junction-to-case thermal resistance. Consider derating curves for ambient temperatures exceeding standard operating ranges.

Bridge Rectifier Part Context

This part belongs to the UD3KB family of bridge rectifiers, which spans voltage ratings from 50V to 1000V. The UD3KB100-BP represents the highest voltage variant in this specific package style, designed for robust performance in demanding electrical environments while maintaining compact physical dimensions.

Bridge Rectifier Replacement Considerations

Direct substitutes include other 3A, 1000V bridge rectifiers in the D3K-4 package such as the MB3100 or similar equivalents from other manufacturers, provided pinout compatibility and thermal characteristics match.
