100 V, 8 A Schottky — rectifier stage fit
The STPS8H100FP is a 100 V, 8 A Schottky rectifier from STMicroelectronics, housed in a TO-220 Full Pack isolated tab package (TO-220FPAC). It is designed for high-frequency rectification in power supplies, freewheeling diodes in DC-DC converters, and reverse-polarity protection circuits where low forward voltage drop and fast recovery are needed.
Forward drop and thermal budget at 8 A
The junction temperature is rated to 175 °C. Reverse leakage is 4.5 µA at 100 V, typical for a Schottky at this voltage class. Leakage rises with junction temperature, so the thermal design should account for increased leakage at high load or ambient conditions.
