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 elimunate unstable units.
2) Valid provided that electrodes are kept at ambient temperature.
3) Measured under thermal equilibrium and DC test conditions.
Admissible power dissipation versus ambient temperature
(Valid provided that electrodes are kept at ambient
temperature)
