STPS5H100AFY

Single Diodes Overview

The STPS5H100AFY is an automotive-grade high-voltage Schottky barrier rectifier manufactured by STMicroelectronics. It features a 100 V repetitive peak reverse voltage and a 5 A average forward current rating, housed in the SOD128Flat surface-mount package. The device supports a junction temperature range from -40 °C to +175 °C and exhibits a typical forward voltage of 760 mV at 5 A with low leakage current of 3.5 µA at 100 V. Qualified under AEC-Q101 standards, it includes avalanche capability and is compliant with ECOPACK® regulations.

Single Diodes Feature Summary

• Negligible switching losses for efficient high-frequency operation
• High junction temperature capability up to 175 °C
• Low leakage current with optimized trade-off against forward voltage drop
• Specified avalanche ruggedness for robust performance

Single Diodes Applications

• Automotive board DC-DC converters
• High-frequency miniature switched-mode power supplies
• General automotive electronics requiring AEC-Q101 compliance

Single Diodes Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the delivered parts match the specific SOD128Flat package and AEC-Q101 automotive grade requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain reliability before soldering.

Single Diodes Selection Notes

Select this component when designing automotive circuits requiring a compact surface-mount solution with high thermal stability. The SOD128Flat package suits space-constrained boards, while the 100 V rating provides adequate headroom for standard 12 V automotive systems. Consider the low leakage and fast recovery characteristics for high-efficiency power conversion applications.

Single Diodes Part Context

This part belongs to the STPS5H series of high-voltage Schottky rectifiers designed specifically for automotive environments. The series emphasizes reliability and thermal performance, utilizing advanced trench technology to minimize switching losses. It serves as a specialized alternative to general-purpose diodes in critical vehicle electronic control units and power management modules.

Single Diodes Replacement Considerations

Direct substitutes within the same family include STPS5H100AF (standard SOD-128) and STPS5H100SFY (PSMC/TO-277A package). Verify pinout compatibility and thermal dissipation requirements when transitioning between these package variants.
