KBJA604-BP

Overview

The KBJA604-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 6 A average rectified forward current and a 400 V peak repetitive reverse voltage. The device utilizes glass passivated chip junctions for reliability. Electrical characteristics include a maximum forward voltage of 1.0 V at 3 A, a reverse leakage current of 5 µA at rated voltage, and a non-repetitive peak surge current capability of 150 A. Thermal resistance from junction to case is 3.4 °C/W. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction construction
• High surge forward current capability
• Halogen-free green device compliant with environmental standards

Applications

• General purpose AC to DC power supply rectification
• Industrial control systems requiring through-hole mounting
• Consumer electronics power adapters

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors due to counterfeiting risks. Confirm the BP suffix indicates RoHS compliance. Check for life support restrictions if used in critical medical or safety devices. Ensure storage conditions align with manufacturer guidelines to maintain product integrity.

Selection Notes

Select this component when a 6 A current rating and 400 V blocking voltage are required in a JB package. Consider thermal management as junction-to-ambient resistance is 28 °C/W without a heatsink. Verify that the operating temperature range meets system requirements. Compare surge current ratings against potential load transients.

Part Context

This part belongs to the KBJA6005 through KBJA610 series of 6 Amp bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent current and physical dimensions. The KBJA604 specifically provides the 400 V option within this standardized family.

Replacement Considerations

Other parts in the KBJA6005-KBJA610 series share identical mechanical dimensions and current ratings but differ in voltage ratings. Cross-reference specific voltage requirements before substitution.
