(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 (I ZT 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) Standard Zener voltage tolerance is 5% tolerance.
