Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the following parameters: diode configuration (1 pair common cathode), technology (Schottky), maximum reverse voltage (100 V), average rectified forward current per diode (40A), forward voltage at rated current, speed (fast recovery), reverse leakage current at rated voltage, junction temperature range, mounting type (Through Hole), and package (TO-220-3 / TO-220AB). Only parts meeting these specifications without deviation are listed as valid substitutes.
