Notes:1) The Zener impedance is derived from the 1KHz AC voltage which results when an AC current having an RMS calue 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 .
