It delivers a forward voltage of 770 mV at 1 A and a reverse leakage of 4 µA at 100 V, with a 175°C maximum junction temperature. The Fast Recovery characteristic (≤ 500 ns, > 200 mA) makes it suited for high-frequency rectification and freewheeling in power supplies where switching losses matter, though the 770 mV Vf is higher than a typical low-Vf Schottky — the trade-off buys better high-temperature leakage control. ## Obsolete — no official successor listed ST lists the STPS1H100AFN as Obsolete. The SMA Flat Leads footprint is shared with other ST Schottky diodes in the STPS1H100 family; a parametric search across 100 V, 1 A Schottkys in the same package will identify functional equivalents for cross-sourcing. ## 175°C junction — hot-environment margin Rated for a 175°C maximum junction temperature, this diode can operate in high-ambient environments such as under-hood automotive, industrial PSU secondary rectification, or sealed power modules where the board temperature exceeds 125°C. The 4 µA leakage at 100 V is specified at 25°C; expect it to multiply with temperature, but the 175°C rating gives thermal headroom for derating the 1 A average current in forced-convection or liquid-cooled designs.","metaTitle":"STPS1H100AFN Schottky Diode, 100V 1A, Fast Recovery","metaDescription":"STPS1H100AFN Schottky rectifier: 100 V, 1 A, 770 mV Vf, 4 µA leakage, 175°C Tj.
