Notes:
(1) The Zener Impedance is derived from the 1kH
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.
(2) Valid provided case is kept at ambient temperature.
(3) Measured at thermal equilibrium.
