1) The Zener Impedance is derived from the 60 Hz AC voltage which results when an AC current having an RMS value

points to insure a sharp knee on the breakdown curve and to eliminate unstable units.

2) Valid provided that electrodes are kept at ambient temperature.

3) Measured under thermal equilibrium and DC test conditions.
