KBJA406-BP

Overview

The KBJA406-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a glass passivated chip junction and operates with a peak repetitive reverse voltage of 600 V. The device supports an average rectified forward current of 4 A at a case temperature of 120°C, with a maximum non-repetitive peak surge current of 140 A under standard half-sine wave conditions. Electrical characteristics include a typical forward voltage of 1.0 V at 2 A and a reverse leakage current of 5 µA at 25°C. The component utilizes a JB package for through-hole mounting.

Feature Summary

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

Applications

• General purpose AC to DC power supply conversion
• Bridge rectification in electronic circuits requiring 600V blocking voltage
• Industrial control systems utilizing through-hole mounting

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Ensure the ordering suffix matches the required packaging configuration. Confirm RoHS compliance status based on the specific batch documentation provided by the supplier prior to final procurement decisions.

Selection Notes

Select this component when a 600 V peak reverse voltage rating is required for single-phase bridge rectification. The 4 A average current rating suits applications operating up to 120°C case temperature. Verify thermal resistance requirements against heatsink constraints, as the junction-to-ambient resistance is 30 °C/W without additional cooling.

Part Context

This part belongs to the KBJA series of 4 Amp bridge rectifiers offered by Micro Commercial Components. The series spans voltage ratings from 50 V to 1000 V, sharing identical mechanical dimensions and electrical performance profiles except for the reverse voltage specifications. The KBJA406 variant specifically targets 600 V applications within this standardized family.

Replacement Considerations

Compatible substitutes include other 4 A, 600 V bridge rectifiers in the JB package format. Ensure replacement parts match the 1.0 V forward voltage drop and 140 A surge current capabilities. Verify that alternative manufacturers offer equivalent glass passivation and UL 94 V-0 epoxy ratings.
