Reverse leakage at the 120 V blocking voltage is 275 µA. ## Obsolete — plan a replacement or source surplus The 30 A average rectified current and 120 V reverse voltage define the operating window: this is a high-current, medium-voltage Schottky for power supplies up to a few kilowatts. The 275 µA leakage at 120 V is a factor in standby power budgets; at elevated temperatures leakage rises significantly, so derate the part if the ambient is above 85°C. The fast recovery ≤500 ns is typical for a Schottky (majority-carrier device has no stored charge), but the spec confirms it handles high-frequency switching without reverse-recovery losses. The STPS30M120SR comes in a through-hole I2PAK package (TO-262AA) with three long leads. The metal tab is the anode connection and needs a thermal pad or heatsink for high-current operation. The through-hole form factor is suited for boards where a screw-mount or clip-on heatsink is used, typical in industrial power supplies and motor drives.","metaTitle":"STPS30M120SR Schottky Rectifier, 30 A, 120 V, Fast Recovery","metaDescription":"STPS30M120SR is a 30 A, 120 V Schottky rectifier with fast recovery ≤500 ns.
