Product details

10 A, 100 V Schottky for power rectification

The STPST10H100SF is a 100 V, 10 A Schottky rectifier from STMicroelectronics, housed in a TO-277A (SMPC) surface-mount package. It targets output rectification in switch-mode power supplies, freewheeling diodes in DC-DC converters, and reverse-polarity protection circuits where low forward voltage and fast switching are required.

Forward drop and leakage at rated current

Reverse leakage is specified at 26 µA when blocking 100 V; while low at 25°C, leakage doubles with every 10°C rise in junction temperature, so the thermal budget at 175°C junction maximum needs a derating calculation.

Fast recovery and switching edge

Rated for fast recovery with trr ≤ 500 ns at forward current above 200 mA, this diode suits continuous-current rectification in 100–200 kHz switching converters where a standard recovery rectifier would overheat. The Schottky barrier itself eliminates stored charge, so the recovery time is dominated by the junction capacitance rather than minority-carrier sweep-out.

The TO-277A (SMPC) package exposes a large metal tab on the bottom for solder-down to the PCB copper plane.

It is part of the ECOPACK2 series, meaning the package is halogen-free and RoHS-compliant per ST's material declaration.

Frequently asked questions

Is STPST10H100SF equivalent to STPS10H100?

No, they are not pin-compatible. The STPS10H100 is a through-hole TO-220AC package; the STPST10H100SF is a surface-mount TO-277A. The die ratings are similar (100 V, 10 A), but the package and footprint differ — they cannot be swapped without a board layout change.
