100 V, 20 A Schottky rectifier in TO-220 Full Pack
The STMicroelectronics STPS20M100SFP is a Schottky diode rated for 100 V DC reverse voltage and 20 A average rectified current, housed in a TO-220-3 Full Pack (TO-220FPAB) through-hole package. 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.
