Notes:
(1) The Zener Impedance is derived from the 60Hz 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 that leads at a distance of 8 mm from case are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
