1) The zener impedance is derived from the 60Hz AC voltage which results when on AC current having an RMS value equal to 10% of the Zener

current (IzT or IZK) is superimposed on IzT or IZK Zener impedance is measured at two points to insure a sharp knee on the breakdown curve

and to eliminate unstable units.

2) Vaild provided that leads at a distance of 8mm from case are kept at ambient temperature.

3) Measured under thermal equilibrium and DC test conditions.
