STPST8H100SF

Single Diodes Overview

The STPST8H100SF is an automotive-grade, single Schottky trench rectifier manufactured by STMicroelectronics. It features a maximum repetitive peak reverse voltage (VRRM) of 100 V and an average forward current (IF(AV)) of 8 A at a case temperature of 155 °C. The device supports a maximum operating junction temperature (Tj) of +175 °C and withstands a non-repetitive surge forward current (IFSM) of 200 A for 10 ms. Typical forward voltage drop (VF) is 0.625 V at 8 A and 25 °C, with a typical reverse leakage current (IR) of 17 µA at 25 °C and 100 V. It utilizes the PSMC (TO-277A) flat package.

Single Diodes Feature Summary

• High junction temperature capability up to 175 °C
• Low forward voltage drop and low recovery charges
• Avalanche tested for ruggedness
• ECOPACK2 compliant flat package design

Single Diodes Applications

• DC/DC converters
• Auxiliary power supplies in telecom, server, or smart metering
• Freewheeling, OR-ring, or reverse polarity protection
• Switch mode power supplies (SMPS)

Single Diodes Procurement Notes

Verify the specific ordering code STPST8H100SF against the manufacturer's datasheet DS14187 Rev 2 to confirm the PSMC (TO-277A) package and tape-and-reel delivery mode. Ensure compatibility with AEC-Q101 automotive qualification requirements if applicable to the target system. Cross-reference thermal resistance parameters and absolute ratings during final design validation.

Single Diodes Selection Notes

Select this component for high-frequency miniature switched mode power supplies requiring efficient VF/IR trade-offs. The 175 °C junction temperature rating allows for robust operation in thermally constrained environments. Consider the TO-277A package dimensions for space-saving PCB layouts. Verify that the 100 V reverse voltage rating exceeds the maximum circuit voltage spikes.

Single Diodes Part Context

This part belongs to the STPST8H100 series of power Schottky trench rectifiers. The 'SF' suffix indicates the specific packaging configuration as tape and reel in the PSMC (TO-277A) format. The series leverages ST trench technology to minimize conduction and switching losses compared to standard Schottky diodes.

Single Diodes Replacement Considerations

Direct substitutes include other ST trench rectifiers in the same family, such as STPST5H100SB or STPST16H100C, provided pinout and electrical ratings match. Verify package compatibility when replacing with devices from other manufacturers.
