KBJA408-BP

Overview

The KBJA408-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a maximum average forward rectified current of 4 A and a peak repetitive reverse voltage of 800 V. The device utilizes glass passivated chip junctions for enhanced stability. Electrical characteristics include a typical forward voltage of 1.0 V at 2 A and a maximum reverse leakage current of 5 µA at 25°C, rising to 100 µA at 125°C. The component operates within a junction temperature range of -55°C to 150°C and supports a non-repetitive peak surge current of 135 A under an 8.3 ms half-sine wave condition.

Feature Summary

• Glass passivated chip junction construction
• Halogen-free green device compliant with environmental standards
• Epoxy material meets UL 94 V-0 flammability rating
• High surge forward current capability

Applications

• General purpose AC to DC power supply conversion
• Bridge rectifier circuits in electronic equipment
• Power adapter applications requiring through-hole mounting

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm the "BP" suffix indicates RoHS compliance and lead-free finish. Ensure storage conditions align with manufacturer guidelines to maintain product integrity prior to assembly.

Selection Notes

Select this component when a 4 A continuous current rating and 800 V blocking voltage are required for through-hole applications. Consider the thermal resistance values for heatsinking requirements if operating near maximum ratings. Verify that the JB package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the KBJA4005 through KBJA410 series of 4 Amp bridge rectifiers. The series offers varying reverse voltage ratings from 50 V to 1000 V while maintaining consistent current handling and physical packaging specifications across all variants in the lineup.

Replacement Considerations

Compatible substitutes within the same series include KBJA406-BP (600 V) and KBJA410-BP (1000 V), provided the voltage rating meets circuit requirements. Other 4 A bridge rectifiers in the JB package may be considered if electrical parameters match.
