Its fast recovery characteristic (≤ 500 ns at > 200 mA) suits it for high-frequency rectification in switched-mode power supplies, freewheeling diodes, and polarity protection circuits where low forward voltage drop and fast switching are required. The fully isolated package simplifies heatsink attachment without an insulating pad, a practical advantage in industrial power stages. ## Forward drop and leakage at rated current At 20 A forward current the maximum forward voltage is 850 mV, a figure that drives conduction loss and heatsink sizing in continuous-duty rectifiers. Reverse leakage at 100 V is 40 µA, which rises with junction temperature — the maximum junction temperature is 150 °C. Both numbers are needed for thermal derating: a design running the diode near its current limit at elevated ambient must budget for increased leakage and the resulting self-heating. Buyers should evaluate a pin-compatible alternative within the STPS20 family for new designs or long-term production support.","metaTitle":"STPS20M100SFP Schottky Diode, 100 V 20 A, TO-220FPAB","metaDescription":"STPS20M100SFP is a 100 V, 20 A Schottky rectifier in TO-220 Full Pack.
