Note 2. Zener Voltage (Vz) is measured with junction in thermal equilibrium with 30°C stud temperature.
Note 3.The zener impedance is derived from the 60 cycle A.C. voltage, which results when an AC
current having an RMS value equal to 10% of the DC zener current (IZT or IZK) is superimposed
on IZT or IZK. Zener impedance is measured at 2 points to insure a sharp knee on the breakdown curve and to eliminate unstable units.
