KBJA804-BP

Overview

The KBJA804-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivated chip junctions and operates with an average rectified forward current of 8 A at a case temperature of 95°C. The device supports a peak repetitive reverse voltage of 400 V, with a corresponding RMS reverse voltage of 280 V. It withstands a non-repetitive peak surge current of 150 A under an 8.3 ms half-sine wave condition. Electrical characteristics include a maximum forward voltage of 1.0 V at 4 A, a reverse leakage current of 5 µA at rated voltage and 25°C, and a junction capacitance of 50 pF. The component functions within an operating junction temperature range of -55°C to 150°C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• General purpose AC to DC power supply conversion
• Industrial equipment rectification circuits
• Consumer electronics power adapters

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer to avoid counterfeit components. Confirm RoHS compliance status via the "BP" suffix designation. Ensure storage conditions align with standard semiconductor handling protocols. Check for specific lot traceability requirements if applicable to your manufacturing quality standards.

Selection Notes

Select this component when a through-hole bridge rectifier with 8 A continuous current capacity and 400 V blocking voltage is required. Consider the thermal resistance values for heatsinking calculations if operating near maximum ratings. Verify that the JB-4 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the KBJA series of bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 8 A current rating. The KBJA804-BP specifically addresses applications requiring 400 V reverse voltage tolerance.

Replacement Considerations

Cross-reference with other KBJA series parts for different voltage ratings. Verify pinout compatibility with existing designs before substituting.
