KBP406G

Overview

The KBP406G is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a maximum average forward rectified current of 4 A and a peak repetitive reverse voltage rating of 600 V. The device utilizes standard rectification technology and is housed in a KBP surface-mount package, specifically identified as 4-ESIP. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at the rated current and a low reverse leakage current of 5 µA at the maximum reverse voltage. The component supports a wide operating junction temperature range from -55°C to 150°C.

Feature Summary

• Provides full-wave rectification for AC to DC conversion in power supply circuits.
• Designed for surface-mount assembly using the compact KBP form factor.
• Capable of withstanding high junction temperatures up to 150°C.

Applications

• General-purpose AC to DC power supply rectification
• Adapter and charger input stages
• Low-power industrial control systems

Procurement Notes

Verify the manufacturer part number against official SMC Diode Solutions documentation to ensure authenticity. Confirm that the specific order suffix matches the required specifications, as variations may exist within the product line. Cross-reference datasheet parameters such as thermal resistance and packaging details with the supplier's latest release notes before finalizing procurement decisions.

Selection Notes

Select this component when a 4 A current capacity and 600 V reverse voltage rating are required for surface-mount applications. Ensure the PCB layout accommodates the KBP package dimensions and thermal requirements. Compare the 1.1 V forward voltage drop against system efficiency targets and verify that the 150°C junction temperature limit aligns with the intended operating environment constraints.

Part Context

The KBP406G belongs to the KBP series of single-phase bridge rectifiers offered by SMC Diode Solutions. This series is characterized by its surface-mount capability and robust performance in general-purpose rectification tasks. The '406' designation typically indicates the 4 A current and 600 V voltage ratings within the manufacturer's nomenclature structure.

Replacement Considerations

Compatible alternatives include the MCC KBP406G-BP, which shares identical 4 A and 600 V specifications and the KBP package type. Verify pinout compatibility and thermal characteristics when substituting components from different manufacturers.
