Substitute Part Grouping Explanation

Substitution logic for Schottky diodes in this category is defined strictly by these parameters:

Diode Technology: Schottky
Maximum DC Reverse Voltage (Vr)
Average Rectified Current (Io)
Maximum Forward Voltage (Vf) at given test current
Reverse Leakage Current at specified voltage
Surface mount package compatibility (SC-79, SOD-523)
RoHS and REACH compliance
Moisture Sensitivity Level (MSL)
Product activity status

Substitute parts are grouped only if they meet or exceed the limits set by the main part in these parameters.
