KMB220S

Overview

The KMB220S is a single-phase Schottky bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 200V and an average rectified output current of 2A. The device utilizes a surface-mount MBS (Molded Bridge Small) package with gull-wing terminals, specifically the 4-SMD configuration. Electrical characteristics include a forward voltage of 900mV at 2A and a reverse leakage current of 50µA at 200V. It operates within a junction temperature range of -55°C to +150°C and holds a Moisture Sensitivity Level of 1.

Feature Summary

• Schottky barrier technology for low power loss and high efficiency
• Plastic case material with UL flammability classification 94V-0
• Surge overload rating capable of handling 50A peak current

Applications

• Automatic assembly processes in surface mount technology lines
• General purpose rectification in low to medium power DC circuits
• Power supply units requiring compact bridge rectifier solutions

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet N1952 to ensure correct packaging and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to placement. Ensure storage conditions align with the specified moisture sensitivity level requirements.

Selection Notes

Select this component when a 2A current rating and 200V blocking voltage are required in a surface-mount form factor. The Schottky technology offers lower forward voltage drop compared to standard silicon diodes, improving overall system efficiency. Verify that the thermal management design supports the specified junction temperature limits under expected load conditions.

Part Context

The KMB220S belongs to the KMB22S through KMB225S series of single-phase surface mount Schottky bridge rectifiers from SMC Diode Solutions. This series provides various voltage ratings while maintaining consistent current handling and package dimensions, allowing for design flexibility across different power supply architectures without changing the footprint.

Replacement Considerations

Compatible substitutes within the same series include KMB22S, KMB24S, KMB26S, KMB28S, KMB210S, KMB212S, KMB215S, KMB220S, and KMB225STR. Ensure the replacement part matches the required voltage rating and maintains the same MBS package type for direct board compatibility.
