Substitute Part Grouping Explanation

Substitute parts for the DDZX6V2B-13 are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Zener voltage (Vz) of 6.2 V nominal
Tolerance of ±3%
Maximum power rating of 300 mW
Maximum impedance (Zzt) of 7 Ohms
Reverse leakage current of 500 nA @ 4 V
Forward voltage (Vf) of 900 mV maximum @ 10 mA
Operating temperature range of -65°C to 150°C
Surface mount configuration in SOT-23-3 package
RoHS3 compliance and MSL 1 rating

The DDZX6V2B-7 meets all specified parameters and is therefore classified as a parametric equivalent within the DDZX6 base product family.
