UD3KB05-BP

Bridge Rectifier Overview

The UD3KB05-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivated chip junctions and epoxy meeting UL 94 V-0 flammability ratings. The device supports an average rectified forward current of 3 A at a case temperature of 140°C, with a peak repetitive reverse voltage of 50 V. Key electrical parameters include a maximum reverse current of 100 µA at 125°C, a typical forward voltage of 1.0 V at 1.5 A, and a non-repetitive peak surge current of 90 A for an 8.3 ms half-sine wave. The component operates within a junction temperature range of -55°C to 150°C.

Bridge Rectifier Feature Summary

• High surge forward current capability
• Epoxy meets UL 94 V-0 flammability rating

Bridge Rectifier Applications

• General purpose rectification in power supplies
• AC to DC conversion circuits
• Low voltage power adapter designs

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer to avoid counterfeit components. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with standard semiconductor handling guidelines to maintain product integrity prior to assembly.

Bridge Rectifier Selection Notes

Select this component for applications requiring 50 V blocking voltage and 3 A continuous current capacity. Consider thermal resistance values when designing heatsinking solutions. Verify that the operating environment stays within the specified junction temperature limits to ensure reliable performance over the intended lifespan.

Bridge Rectifier Part Context

This part belongs to the UD3KB series of bridge rectifiers, which covers a voltage range from 50 V to 1000 V. The series utilizes a D3K package format suitable for through-hole mounting. The specific model provides the lowest voltage option in this high-current family, designed for general-purpose low-voltage AC rectification tasks.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 3 A current rating, 50 V reverse voltage, and D3K package dimensions. Verify equivalent forward voltage drop and thermal resistance characteristics to ensure circuit compatibility without redesigning the cooling infrastructure.
