Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching electrical and mechanical parameters that define component compatibility within the Diodes, Zener category. The parameters considered are: Zener voltage (2.2 V), tolerance (±4.32%), maximum power rating (150 mW), maximum impedance (100 Ohms), reverse leakage current (120 µA @ 700 mV), operating temperature (150°C), mounting type (Surface Mount), package and supplier device package (SC-79, SOD-523, EMD2), RoHS compliance, MSL, and qualification status (AEC-Q101 Automotive). The substitute part, EDZVT2R2.2B, aligns with all these parameters.
