100 V / 8 A Schottky — TO-220AC through-hole
The STPS8H100D is a 100 V, 8 A Schottky rectifier from STMicroelectronics in a TO-220AC through-hole package. It delivers a forward voltage drop of 710 mV at 8 A and a reverse leakage of 4.5 µA at 100 V. The Schottky barrier technology gives it fast recovery — under 500 ns — which suits switch-mode power supply output rectification and freewheeling diode roles in DC-DC converters.
Junction temperature and leakage at 175 °C
Rated for a maximum junction temperature of 175 °C. At that ceiling, the reverse leakage current rises sharply — the 4.5 µA figure at 100 V is a 25 °C spec; budget for a multiple at full operating temperature. The TO-220AC tab provides a direct thermal path to a heatsink if the application runs near the current limit.
