* The Zener Impedance is derived from the 60 H
Z
AC voltage which results when an AC current having an RMS
value equal to 10% of the Zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
. Zener Impedance is measured at
two points to insure a sharp knee on the breakdown curve and to eliminate unstable units.
*Valid provided that electrodes are kept at ambient temperature
*** Measured under thermal equilibrium and DC test conditions
