Notes:
(1) The Zener impedance is derived from the 1kHz 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 electrodes are kept at ambient temperature
(3) Tested under thermal equilibrium and DC test conditions
