Notes:
(1) The Zener Impedance is derived from the 60 Hz 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.
(2) Valid provided that electrodes are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
