KBP4005G

Overview

The KBP4005G is a single-phase bridge rectifier manufactured by SMC Diode Solutions, designed for through-hole mounting in the KBP package. It features a peak repetitive reverse voltage of 50 V and an average rectified output current of 4.0 A. The device exhibits a maximum forward voltage drop of 1 V at rated current and a low reverse leakage current of 5 µA. It supports a maximum surge current of 120 A and operates within a junction temperature range of -65 °C to +150 °C. The component dimensions are 25.2 mm in length, 9.7 mm in width, and 19.3 mm in height.

Feature Summary

• Glass passivated die construction ensures stable reverse blocking characteristics.
• Plastic molding compound meets UL flammability classification 94V-0.
• Terminals are plated and solderable per MIL-STD-202 Method 208.

Applications

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

Procurement Notes

Verify the manufacturer marking matches SMC Diode Solutions specifications. Confirm RoHS compliance status via official documentation. Ensure the part number suffix aligns with required packaging formats. Cross-reference datasheet revisions to validate electrical parameters against design requirements.

Selection Notes

Select this component when a 50 V rating and 4 A continuous current capacity are required. The KBP package offers robust mechanical stability for through-hole assembly. Consider thermal management constraints given the 150 °C maximum junction temperature limit during high-load operations.

Part Context

This component belongs to the KBP series of glass passivated bridge rectifiers from SMC Diode Solutions. The series provides various voltage ratings while maintaining consistent 4 A current capability and standardized physical dimensions for board layout compatibility across different power supply designs.

Replacement Considerations

Direct substitutes include the KBJ4005G from Diodes Incorporated, which shares identical electrical ratings and pinout configuration. Verify package tolerance and terminal plating specifications before substitution.
