The Zener Impedance is derived from the 60 Hz AC voltage which results when an AC current having an RMS value equal to 10% of the
Zener current (I
ZT
or l
w
) is superimposed on l^ or I
ZK
Zener Impedance is measured at two po nts to insure a sharp knee on the breakdown
curve and to eliminate unstable units.
Valid provided that leads at a distance of 8 mm from case are kept at ambient temperature.
Measured under thermal equilibrium and DC test conditions.
