Product details

The STPS5H100H is a 100 V, 5 A Schottky rectifier from ST, housed in a through-hole TO-251 (IPAK) package. Its 730 mV forward voltage at 5 A is typical for a 100 V Schottky — the trade-off is lower Vf than a 200 V part, but you give up reverse voltage headroom. The 3.5 µA reverse leakage at 100 V is low enough for most power-supply output rectification and freewheeling diode roles.

ST lists the STPS5H100H as obsolete. No official successor is recorded.

Through-hole TO-251 (IPAK) — board-fit note

The TO-251 (IPAK) is a three-lead through-hole package with short leads, designed for vertical mounting on the PCB. The tab is the cathode.

Frequently asked questions

What is the difference between STPS5H100H and STPS5L100?

Both are 100 V, 5 A Schottky rectifiers in TO-251. The STPS5L100 is a low-drop variant with a lower forward voltage (typically 630 mV at 5 A vs 730 mV for the STPS5H100H), but its reverse leakage is higher. Pin-compatible — same footprint, same cathode tab.
