Notes
(1) The Zener impedance is derived from the 1 kHz AC voltage which results when an AC current having an RMS value equal to 10 % of the
Zener current (IZT1 or IZT2) is superimposed on IZT1 or IZT2. 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
(4) Width of the test pulse is 8.3 ms
