The zener impedance is derived from the 1 kHz AC voltage which results when an 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
