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 leads at a distance of 8mm from case are kept at ambient temperature.
3) Measured under thermal equilibrium and DC test conditions.
Admissible power dissipation versus ambient temperature
(Valid provided that leads at a distance of 10mm from case
are kept at ambient temperature)
