KBJA404-BP

Overview

The KBJA404-BP is a single-phase bridge rectifier from the KBJA series manufactured by Micro Commercial Components. It features a 4 A average rectified forward current and a 200 V peak repetitive reverse voltage rating. The device utilizes glass passivated chip junctions for reliability and meets UL 94 V-0 flammability standards. Electrical characteristics include a maximum forward voltage of 1.0 V at 2 A and a reverse leakage current of 5 µA at rated voltage. It supports a non-repetitive peak surge current of 135 A and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

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

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial electronics

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase, as counterfeiting is a known industry risk. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component for applications requiring 4 A continuous current and 200 V blocking voltage. Consider thermal resistance values when designing heatsinking solutions. Verify that the JB package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the KBJA series of 4 Amp bridge rectifiers covering voltage ratings from 50 V to 1000 V. The series shares common mechanical and electrical baseline specifications, differentiated primarily by the peak repetitive reverse voltage rating indicated in the model number.

Replacement Considerations

Compatible substitutes include other 4 A bridge rectifiers in the JB package with equal or higher voltage ratings, such as the KBJ404 or equivalent parts from other manufacturers meeting the same electrical and dimensional specifications.
