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) Measured under thermal equilibrium and DC test condit ions.
