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 am bient temperature
(3) Tested under thermal equilibrium and DC test conditions.
