Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on alignment of electrical and mechanical parameters: technology type (Schottky), voltage rating (40 V reverse), current rating (2.2A average rectified), forward voltage (540 mV @ 2 A), reverse recovery time (6 ns), leakage current (40 µA @ 30 V), capacitance (65pF @ 30V, 1MHz), automotive grade, AEC-Q101 qualification, package type (SOT-23-6/SOT-26), junction temperature (150°C), RoHS and REACH compliance, and identical mounting requirements. Only parts with matching specifications in these listed parameters are considered direct substitutes.

Parameter Comparison
