KBJA608-BP

Overview

The KBJA608-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a peak repetitive reverse voltage of 800 V and an average rectified forward current of 6 A. The device exhibits a maximum forward voltage of 1.0 V at 3 A and a reverse leakage current of 5 µA at 25°C, rising to 100 µA at 125°C. Non-repetitive peak surge current capability reaches 150 A under an 8.3 ms half-sine wave condition. Thermal resistance from junction to case is 3.4 °C/W, with an operating junction temperature range spanning -55°C to +150°C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Halogen-free "Green" device construction
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• General-purpose AC to DC power supply conversion
• Industrial control systems requiring high surge current tolerance
• Automotive electronics applications

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase channels. Counterfeit components are prevalent in the market; unauthorized sources lack traceability and quality assurance. Confirm RoHS compliance via the "BP" suffix designation. Ensure ordering specifications match the required voltage and current ratings before procurement.

Selection Notes

Select this component when an 800 V blocking voltage and 6 A continuous current capacity are required. The JB-4 package offers a compact footprint suitable for space-constrained designs. Evaluate thermal management requirements based on the specified junction-to-case resistance. Consider derating curves for operation above standard ambient temperatures.

Part Context

This part belongs to the KBJA series of glass-passivated bridge rectifiers from Micro Commercial Components. The series covers voltage ratings from 50 V to 1000 V with a consistent 6 A current rating. The KBJA608-BP specifically addresses applications needing robust reverse voltage handling within a standard through-hole mounting configuration.

Replacement Considerations

Cross-reference with other 6 A, 800 V bridge rectifiers in the JB-4 package. Verify pinout compatibility and physical dimensions before substitution. Ensure replacement devices meet equivalent thermal and electrical performance standards.
