Zener impedance is derived from the 1KHz AC voltage which results when an AC current having and RMS value
equal to 10% if the Zener current is superimposed on IZT or IZK.
Measured under thermal equilibrium and DC test conditions
Valid provide that electrodes at a distance of 10mm from the case are kept at ambient temperature.
