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 (IZT) is superimposed on IZT.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 leads at a distance of 3/8 " from case are kept at ambient temperature.
3)Measured with device junction in thermal equilibrium.
