SK14

Single Diodes Overview

The SK14 is a surface-mount Schottky rectifier manufactured by SMC Diode Solutions, housed in the DO-214AA (SMB) package. It features a maximum DC reverse voltage of 40 V and an average forward rectified current rating of 1 A. The device exhibits a typical forward voltage drop of 550 mV at 1 A and a maximum reverse leakage current of 100 µA at 40 V. Operating junction temperatures range from -55°C to +175°C.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for low forward voltage drop and high efficiency
• Designed for surface mount assembly in compact SMB packages
• Engineered for high switching speed applications with minimal reverse recovery charge

Single Diodes Applications

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

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging format, such as tape and reel quantities versus cut tape options. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a low-profile surface mount solution is required for 40 V systems. Ensure the SMB footprint matches the PCB layout constraints. Verify that the 1 A current rating and thermal dissipation capabilities meet the circuit's peak load requirements.

Single Diodes Part Context

This part belongs to the standard Schottky rectifier family from SMC Diode Solutions. It serves as a surface-mount alternative to through-hole axial packages, offering similar electrical characteristics in a smaller form factor suitable for automated assembly processes.

Single Diodes Replacement Considerations

Direct replacements include other SMB-packaged Schottky diodes with matching 40 V and 1 A ratings, such as the SB140 in different packaging or equivalent parts from other manufacturers like SS14.
