Notes:
1. 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 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. Tested under thermal equilibrium and DC test conditions
