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
