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 I
ZT 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 electrodes are kept at ambient temperature
(3) Tested under thermal equilibrium and DC test conditions
