NOTES
(1) The Zener impedance is derived from the 1kHz 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 IZTor 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 electrodes are kept at ambient temperature
(3) Tested under thermal equilibrium and DC test conditions
