Notes:
(1) The Zener impedance is derived from the 1KHZ AC volt age which results when an AC current having an RMS value equal to 10% of the Zener current (IZTor IZK)
is superim posed on IZT or IZK. Zener impedance is m easured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units.
(2) Valid provided that electrodes at a distance of 10mm from case are kept at ambient temperature.
(3) Tested under thermal equilibrium and DC test conditions.
