Notes: (1) The Zener impedance is derived from the 1KHZ AC volt age which results when an AC current having an RMS value equal
the Zener current (IZTor IZK) is superim posed 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 at a distance of 10mm from case are kept at ambient temperature
(3) Tested under thermal equilibrium and DC test conditions.
