2 / 3 page Notes: (1) The Zener Impedance is derived from the 60 Hz AC voltage which results when an AC current having an RMS value equal to 10% of the Zener current (I ZT 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 8 mm from case are kept at ambient temperature. (3) Measured under thermal equilibrium and DC test conditions.
