KBJ4005G-BP

Overview

The KBJ4005G-BP is a single-phase glass passivated bridge rectifier manufactured by Micro Commercial Components. It features a maximum average forward rectified current of 4.0 A and a peak repetitive reverse voltage of 50 V. The device utilizes glass passivated die construction to ensure low reverse leakage current and high case dielectric strength of 1500 V RMS. It is housed in a KBJ molded plastic package with UL 94V-0 flammability rating, designed for through-hole mounting on printed circuit boards.

Feature Summary

• Glass passivated chip junction construction
• High case dielectric strength of 1500 V RMS
• Low reverse leakage current characteristics
• Molded plastic material with UL 94V-0 flame retardant rating

Applications

• Printed circuit board mounting for AC-to-DC conversion
• General purpose power supply rectification
• Industrial control systems requiring reliable bridge rectification

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm RoHS compliance details directly from the manufacturer's documentation. Ensure that the specific batch availability aligns with project timelines, given potential discontinuation risks associated with older series components.

Selection Notes

Select this component when a 4 A current rating and 50 V reverse voltage are required for single-phase bridge rectification. The KBJ package form factor is suitable for applications needing robust mechanical stability and high dielectric isolation. Consider thermal derating requirements if operating near the maximum junction temperature limit of 150 °C under capacitive load conditions.

Part Context

This part belongs to the KBJ series of glass passivated bridge rectifiers from Micro Commercial Components. It shares the same physical footprint and general construction principles as other variants in the series, differing primarily in voltage ratings. The KBJ series is widely used in general-purpose electronics where cost-effective, reliable rectification is necessary.

Replacement Considerations

Direct substitutes include the Diodes Inc. KBJ4005G and Vishay KBJ4005G, which share identical electrical specifications and pinout configurations. Cross-reference datasheets to confirm mechanical dimensions and terminal solderability standards match the original design requirements.
