KBJA808-BP

Overview

The KBJA808-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an average forward current of 8 A at a case temperature of 95°C and a peak repetitive reverse voltage of 800 V. The device utilizes glass passivated chip junctions and epoxy meeting UL 94 V-0 flammability ratings. Electrical characteristics include a maximum reverse current of 100 uA at 125°C and a typical junction capacitance of 50 pF. The component operates within a junction temperature range of -55°C to 150°C and offers high surge forward current capability with an IFSM rating of 150 A for an 8.3ms half-sine wave.

Feature Summary

• Glass passivated chip junction construction
• Halogen-free green device compliant with environmental standards
• Epoxy material meets UL 94 V-0 flammability rating
• Lead-free finish with RoHS compliance designation

Applications

• General purpose AC to DC conversion in power supplies
• Bridge rectification in industrial control systems
• High voltage rectification circuits requiring 800V blocking capability

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Ensure the ordering suffix BP confirms RoHS compliance and lead-free finish. Confirm package type JB-4 and pinout compatibility with target PCB layouts before integration into production assemblies.

Selection Notes

Select this component when an 800 V peak repetitive reverse voltage rating is required alongside an 8 A average rectified forward current capacity. Consider the thermal resistance from junction to ambient of 28°C/W for heatsinking requirements. Verify that the operating environment stays within the specified -55°C to 150°C junction temperature range for reliable performance.

Part Context

This part belongs to the KBJA8005 through KBJA810 series of single-phase bridge rectifiers. The series shares identical physical dimensions, thermal characteristics, and general electrical structures, differing primarily in their peak repetitive reverse voltage ratings which range from 50 V to 1000 V. All variants utilize the same JB-4 through-hole package.

Replacement Considerations

Cross-reference with other 8 A, 800 V single-phase bridge rectifiers in the JB-4 package. Verify matching forward voltage drop, reverse leakage current, and surge current capabilities. Ensure pinout configuration and mounting torque specifications align with existing design constraints.
