The 20 A average rectified current (Io) sets the continuous load capacity. Forward voltage drop is 840 mV at 20 A, typical for a 120 V Schottky. Reverse leakage at 120 V is 275 µA — acceptable for most designs but worth checking at elevated junction temperature (max 150 °C). STMicroelectronics lists the STPS20M120SR as obsolete. For new designs, consider a current-production 20 A, 120 V Schottky in TO-262 from ST's portfolio or a second-source equivalent.","metaTitle":"STPS20M120SR Schottky Diode, 20A 120V Fast Recovery TO-262","metaDescription":"STPS20M120SR Schottky diode: 20A average rectified current, 120V reverse voltage, fast recovery ≤500ns.
