Notes:
1. Measured under thermal equilibrium and DC (IZT ) test conditions.
2. The Zener impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value equal to
10% of the Zener current (IZT or I ZK) 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.
