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 leads at a distance of 10 mm from case are kept at ambient temperature.
(3) Measured with a pulse test current.
