VSSAF3103HM3/I

Single Diodes Overview

The Vishay VSSAF3103HM3/I is a surface-mount Trench MOS Barrier Schottky (TMBS) rectifier housed in a SlimSMA (DO-221AC) package. It features an average forward current rating of 3 A and a maximum repetitive peak reverse voltage of 100 V. The device supports a peak forward surge current of 80 A and operates within a junction temperature range of -40 °C to +150 °C. At a junction temperature of 125 °C and forward current of 3 A, the typical forward voltage drop is 0.52 V. The component is halogen-free, RoHS-compliant, and qualified under AEC-Q101 standards for automotive applications.

Single Diodes Feature Summary

• Utilizes Trench MOS Schottky technology to achieve low power losses and high efficiency
• Features a very low profile with a typical height of 0.95 mm suitable for automated placement
• Meets MSL level 1 requirements per J-STD-020 with a maximum peak reflow temperature of 260 °C

Single Diodes Applications

• High frequency inverters
• Freewheeling circuits
• DC/DC converters
• Polarity protection in commercial, industrial, and automotive systems

Single Diodes Procurement Notes

Verify that the ordering suffix /I corresponds to the 13-inch diameter plastic tape and reel delivery mode as specified in the manufacturer's documentation. Confirm compliance with RoHS and REACH directives by referencing the official Vishay material categorization documents. Ensure the specific variant selected matches the required AEC-Q101 qualification status for intended automotive deployments.

Single Diodes Selection Notes

Select this component when a compact SlimSMA footprint is required alongside a 3 A continuous current capability. The TMBS architecture provides superior switching performance compared to standard planar diodes. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance values for the target PCB copper pad area.

Single Diodes Part Context

This part belongs to the Vishay eSMP series of surface-mount Schottky rectifiers. It shares the SlimSMA (DO-221AC) mechanical casing with other variants in the family but is distinguished by its specific 3 A current rating and 100 V blocking voltage characteristics defined by the base part number VSSAF3103.

Single Diodes Replacement Considerations

Direct substitutes include VSSAF3103-M3/I for non-automotive specifications and VSSAF3103HM3/H for alternative reel packaging configurations. Verify pinout compatibility and thermal resistance parameters before substituting.
