KBP404G-BP

Overview

The KBP404G-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 4A with a peak repetitive reverse voltage of 400V. Electrical characteristics include a maximum forward voltage of 1.0V at 2A and a reverse leakage current of 5µA at 25°C, rising to 100µA at 125°C. Thermal resistance from junction to case is 5°C/W, while junction to ambient is 45°C/W without a heatsink. The component operates within a temperature range of -55°C to 150°C.

Feature Summary

• Glass passivated chip junctions for enhanced reliability
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• General purpose AC to DC power supply conversion
• Bridge rectifier circuits in electronic equipment
• Power adapter applications requiring 400V reverse voltage

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Ensure the ordering suffix matches the required RoHS compliance status. Confirm packaging details align with project needs, as bulk tubes contain 35 pieces per tube. Check for specific handling requirements regarding storage and soldering temperatures.

Selection Notes

Select this component when a 4A continuous current and 400V blocking voltage are required in a surface-mountable DIP-like package. Consider thermal management if operating near maximum ratings, as ambient thermal resistance is 45°C/W. Verify that the 1.0V forward voltage drop fits system efficiency targets. Ensure the application does not involve life support systems without explicit manufacturer approval.

Part Context

This part belongs to the KBP series of single-phase bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50V to 1000V while maintaining a consistent 4A current capacity. The KBP404G variant specifically addresses applications requiring 400V peak reverse voltage. The 'BP' suffix indicates RoHS compliance and lead-free finish.

Replacement Considerations

Compatible substitutes within the same family include KBP406G-BP (600V) and KBP408G-BP (800V) for higher voltage requirements. For lower voltage needs, KBP402G-BP (200V) may be suitable. Ensure any replacement maintains the 4A current rating and compatible package dimensions.
