It is rated for fast recovery (≤500 ns at >200 mA). The 630 mV forward drop at 20 A is the figure to budget for conduction loss. STMicroelectronics lists the STPS20SM60ST as obsolete. ## Junction temperature and thermal limits The maximum junction temperature is 150°C. That is the absolute ceiling for the silicon; continuous operation near that limit requires careful thermal management — the TO-220's junction-to-case thermal resistance is the number to pull from the datasheet for heatsink sizing. The 85 µA reverse leakage at 60 V is specified at 25°C; leakage roughly doubles for every 10°C rise, so at elevated junction temperatures the standby loss contribution grows.","metaTitle":"STPS20SM60ST Schottky Diode, 20A 60V, TO-220","metaDescription":"STPS20SM60ST Schottky rectifier, 20A average, 60V reverse, 630mV Vf at 20A, TO-220.
