UD2KB40-BP

Bridge Rectifier Overview

The UD2KB40-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a glass passivated chip junction and operates within a temperature range of -55°C to +150°C. The device provides an average rectified forward current of 2 A at a case temperature of 140°C, with a peak repetitive reverse voltage of 400 V. Key electrical parameters include a maximum reverse current of 10 µA at 25°C and a typical forward voltage of 1.0 V at 1 A. The component utilizes the D3K surface-mount package.

Bridge Rectifier Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating
• Halogen-free "Green" device construction

Bridge Rectifier Applications

• General-purpose AC to DC power supply circuits
• Bridge rectification in low-to-medium power electronic devices
• Industrial control systems requiring robust diode protection

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from Micro Commercial Components Corp. to avoid counterfeit components. Ensure the ordering suffix matches the required RoHS compliance status. Confirm packaging quantities align with production needs, as bulk options are available in tubes and boxes. Check for any specific handling requirements related to the surface-mount D3K package during assembly.

Bridge Rectifier Selection Notes

Select the UD2KB40-BP when a 400 V peak repetitive reverse voltage rating is required for single-phase bridge rectification. This component is suitable for applications demanding a 2 A average forward current capability. Consider the D3K surface-mount package for PCB space constraints. Evaluate thermal management requirements, as the device requires heatsinking for optimal performance above 25°C ambient temperatures.

Bridge Rectifier Part Context

The UD2KB40-BP belongs to the UD2KB series of bridge rectifiers from Micro Commercial Components. This series covers voltage ratings from 50 V to 1000 V, offering standardized mechanical dimensions across the family. The UD2KB40 specifically targets applications needing 400 V blocking capability while maintaining the 2 A current rating common to this package type.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 2 A current rating, 400 V reverse voltage, and D3K surface-mount package. Verify that alternative components offer comparable surge current capabilities and thermal resistance characteristics. Ensure compatibility with existing PCB footprints and mounting torque specifications.
