Substitute Part Grouping Explanation

Substitute parts for the BAV99QC-QZ are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

Voltage Rating: DC reverse voltage must equal 100 V
Current Rating: Average rectified current per diode must equal 215 mA (DC)
Forward Voltage Drop: Maximum forward voltage at 150 mA must equal 1.25 V
Recovery Characteristics: Reverse recovery time must equal 4 ns; fast recovery classification must be maintained
Reverse Leakage: Current leakage at rated reverse voltage must equal 500 nA @ 80 V
Temperature Rating: Junction temperature rating must equal 150°C
Diode Configuration: Must maintain 1 Pair Series Connection topology
Package Specification: Must use 3-XDFN Exposed Pad with wettable flank construction
Mounting Technology: Must be surface mount compatible

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
