KMB25S

Overview

The KMB25S is a single-phase Schottky bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 50 V and an average rectified output current of 2 A. The forward voltage drop is specified as 700 mV at 2 A, with a maximum reverse leakage current of 100 µA at 50 V. Designed for surface mount applications, it utilizes the MBS (4-SMD,鸥翼) package. The device operates within a junction temperature range of -55°C to 150°C and supports non-repetitive peak forward surge currents up to 50 A.

Feature Summary

• Schottky barrier technology enables low power loss and high efficiency conversion.
• Plastic case material meets UL flammability classification 94V-0 standards.
• Surge overload rating accommodates peak currents up to 50 A for robust transient protection.

Applications

• Automatic assembly processes in consumer electronics manufacturing
• Low voltage DC power supply rectification circuits
• Battery charging systems requiring high efficiency

Procurement Notes

Verify the specific ordering suffix to confirm packaging format, such as tape and reel or cut tape, as these affect handling procedures. Ensure compliance with RoHS3 and REACH regulations matches project requirements. Confirm the manufacturer part number against official SMC Diode Solutions documentation to avoid counterfeit components during sourcing.

Selection Notes

Select this component when a 50 V reverse voltage rating and 2 A continuous current capacity are required in a compact surface mount form factor. The Schottky technology is suitable for applications prioritizing low forward voltage drop over higher voltage blocking capabilities. Evaluate thermal management needs based on the 150°C junction temperature limit and ambient operating conditions.

Part Context

The KMB25S belongs to the KMB2 series of single-phase Schottky bridge rectifiers from SMC Diode Solutions. This family includes variants with different voltage ratings, ranging from 20 V to 200 V, all sharing the same 2 A current rating and MBS surface mount package. The series is designed for general-purpose rectification in space-constrained electronic designs.

Replacement Considerations

Compatible substitutes include other 50 V, 2 A surface mount Schottky bridge rectifiers in the MBS package. Verify pinout compatibility and electrical parameters such as forward voltage and reverse leakage before substitution. Ensure the alternative component meets the same thermal and mechanical specifications for direct replacement.
