It is designed for high-current applications such as switch-mode power supply output rectification, freewheeling diodes, and reverse-polarity protection where low forward voltage and fast switching are needed. ## Forward drop and conduction loss at rated current ## Reverse leakage and blocking voltage margin Maximum reverse leakage is 40 µA at 100 V reverse voltage. For a 48 V bus or 60 V rail this leaves at least 40 V of blocking margin, well within typical derating guidelines. The 100 V rating also covers 80 V bus systems with headroom for transients. It is ROHS3 compliant.","metaTitle":"STPS20M100ST Schottky Diode, 100 V 20 A TO-220, Active","metaDescription":"STPS20M100ST Schottky rectifier: 100 V reverse, 20 A average, 850 mV Vf at 20 A.
