Notes
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 break-
down curve and to eliminate unstable units.
