The Zener Impedance is derived from the 1 kHZ 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.
3)
Measured at thermal equilibrium.
