VSSAF5M15-M3/H

Single Diodes Overview

The VSSAF5M15-M3/H is a surface-mount Trench MOS Barrier Schottky (TMBS) rectifier manufactured by Vishay General Semiconductor. It features a SlimSMA (DO-221AC) package with a typical height of 0.95 mm. The device supports a maximum repetitive peak reverse voltage of 150 V and an average forward current of 5.0 A under pulse conditions, or 2.0 A in free air. It exhibits a low forward voltage drop of 0.68 V at 5.0 A and 125 °C. The component operates within a junction temperature range of -40 to +175 °C and meets MSL level 1 requirements.

Single Diodes Feature Summary

• Utilizes Trench MOS Schottky technology for low power losses and high efficiency
• Features a very low profile case suitable for automated placement
• Complies with J-STD-020 standards for moisture sensitivity level 1
• Halogen-free and RoHS-compliant construction

Single Diodes Applications

• High frequency inverters
• Freewheeling circuits
• DC/DC converters
• Polarity protection

Single Diodes Procurement Notes

Verify the specific ordering code suffix when purchasing. The 'HM3' designation indicates AEC-Q101 qualification for automotive applications, whereas the standard 'M3' version does not carry this automotive certification. Confirm that the required quantity matches the base delivery mode, such as 3500 units for the H package or 14000 units for the I package, to ensure correct supply chain fulfillment.

Single Diodes Selection Notes

Select this component for designs requiring a compact surface-mount solution with high thermal stability up to 175 °C. The SlimSMA package offers a low-profile alternative to larger diode packages while maintaining robust surge current capabilities. Ensure the application accounts for the derating curve for average forward current based on the specific mounting temperature and copper pad area utilized in the PCB layout.

Single Diodes Part Context

This part belongs to the eSMP series of surface-mount TMBS rectifiers from Vishay. It shares the SlimSMA (DO-221AC) footprint with other devices in the family but is distinguished by its 150 V rating and 5 A current handling capacity. The product line emphasizes miniaturization and efficiency for modern electronic systems.

Single Diodes Replacement Considerations

Direct substitutes include the VSSAF5M15HM3/H for automotive-grade equivalents. Other Vishay parts in the SlimSMA package with matching electrical ratings may serve as functional replacements if pinout and thermal characteristics align with the design requirements.

Single Diodes FAQ

Is the VSSAF5M15-M3/H qualified for automotive applications?

No, the standard VSSAF5M15-M3/H is not AEC-Q101 qualified. Automotive-grade versions are available with the HM3 suffix, specifically designated as VSSAF5M15HM3/H.

What is the maximum operating junction temperature?

The maximum operating junction and storage temperature range is -40 to +175 °C.
