Its 900 mV maximum forward voltage at the full 20 A rating keeps conduction losses manageable in high-current rectification and freewheeling stages. The fast recovery characteristic (≤ 500 ns, > 200 mA) suits it for switching power supplies and DC-DC converters where reverse-recovery charge needs to be low. STMicroelectronics lists the STPS20SM100SR as obsolete. No official successor is listed by the manufacturer, so a pin-compatible drop-in replacement needs to be qualified from the same Schottky family or a cross-shopped alternative. ## Ratings that matter for the BOM The 20 A average rectified current (Io) sets the continuous load this diode can handle in a forward-biased application — derate for ambient temperature and heatsinking. The 100 V reverse voltage (Vr max) defines the blocking capability; a 900 mV forward drop at 20 A is typical for a 100 V Schottky of this current class. Reverse leakage is specified at 30 µA at 100 V, which is the figure to check for standby power budgets in offline supplies.","metaTitle":"STPS20SM100SR Schottky Diode, 20A 100V, TO-262, Obsolete","metaDescription":"STPS20SM100SR Schottky rectifier, 20 A average, 100 V reverse, 900 mV forward drop at 20 A.
