Reverse leakage is 30 µA at the 100 V rated reverse voltage — a typical Schottky trade-off: the leakage rises with junction temperature, so the 150°C maximum junction rating sets the practical derating for high-ambient or low-airflow enclosures.","metaTitle":"STPS20SM100ST Schottky Diode, 100V 20A TO-220, Active","metaDescription":"STPS20SM100ST Schottky rectifier, 100 V reverse, 20 A average, 900 mV Vf at 20 A.
