KMB125F

Overview

The KMB125F is a single-phase Schottky bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 250 V and an average forward rectified current rating of 1 A. The device utilizes the MBS surface-mount package, specifically a 4-SMD鸥翼 (gull-wing) configuration. Key electrical characteristics include a maximum DC reverse leakage current of 10 µA at 250 V and a typical forward voltage drop of 950 mV at 1 A. The component supports a junction operating temperature range from -55°C to 150°C.

Feature Summary

• Schottky barrier technology for low forward voltage drop and high switching efficiency
• Surface-mount MBS package design for automated PCB assembly
• High surge current capability for transient protection

Applications

• DC-DC converter circuits
• Free-wheeling diodes in power supplies
• Polarity protection applications

Procurement Notes

Verify that the specific order matches the manufacturer part number KMB125F from SMC Diode Solutions. Confirm the package type is the standard MBS surface-mount variant. Ensure compliance with RoHS directives if required by the end application. Cross-reference datasheet specifications against the supplier's certificate of conformity to validate electrical parameters before integration into production.

Selection Notes

Select this component when a surface-mount Schottky rectifier is required for 250 V reverse voltage applications. The 1 A current rating suits moderate power levels where low forward voltage drop is critical for efficiency. The MBS package offers a compact footprint compared to through-hole alternatives, making it suitable for space-constrained designs requiring reliable thermal performance up to 150°C.

Part Context

The KMB125F belongs to the KMB series of single-phase Schottky bridge rectifiers produced by SMC Diode Solutions. This series provides a range of voltage and current ratings tailored for surface-mount applications. The KMB125F specifically addresses the need for efficient rectification in compact electronic devices, leveraging Schottky technology to minimize power loss during conversion processes.

Replacement Considerations

Equivalent parts include KMB125 from other manufacturers with identical 250 V/1 A ratings and MBS packaging. Verify pinout compatibility and thermal resistance values when substituting.
