The Zener impedance is derived from the 1kHz AC voltage which results when an AC current having an RMS
value equal to 10% of the Zener current (IZT) is superimposed on IZT Zener impedance is measured at two points
to insure a sharp knee on the breakdown curve and to eliminate unstable units.
Valid provided that leads are kept at ambient temperature at a distance of 8mm from case.
Measured with device junction in thermal equilibrium.
