KBJA8005-BP

Overview

The KBJA8005-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 supports peak repetitive reverse voltages ranging from 50 V to 1000 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 µA at 125°C and a typical junction capacitance of 50 pF. Thermal resistance from junction to case is 2.8 °C/W, while junction-to-ambient resistance is 28 °C/W without a heatsink. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction construction for enhanced reliability
• High surge forward current capability with I2t rating of 93 A²s
• Epoxy material meets UL 94 V-0 flammability rating
• Halogen-free 'Green' device compliant with RoHS directives

Applications

• General purpose AC to DC power supply conversion
• Bridge rectification in industrial control systems
• Power adapter circuits requiring high surge tolerance

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the "BP" suffix indicates RoHS compliance and lead-free finish. Ensure ordering quantities align with bulk packaging specifications of 20 pieces per tube and 1800 pieces per carton. Request traceability documentation to guarantee quality standards are met during handling and storage.

Selection Notes

Select this component based on the required peak repetitive reverse voltage, which ranges from 50 V to 1000 V across the KBJA80xx series. Consider the 8 A average forward current rating relative to thermal management requirements. Evaluate the need for heatsinking if operating near maximum case temperatures. Verify that the JB package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the KBJA8005 through KBJA810 series of 8 Amp bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V, sharing identical mechanical and thermal characteristics. The KBJA8005 specifically denotes the 50 V variant within this standardized family of glass passivated bridge rectifiers designed for general-purpose applications.

Replacement Considerations

Compatible substitutes within the same MCC series include KBJA801, KBJA802, KBJA804, KBJA806, KBJA808, and KBJA810. These parts share identical current ratings and physical dimensions but differ in peak repetitive reverse voltage ratings. Ensure the replacement voltage rating meets or exceeds the circuit requirements.
