Operating & storage temperature range
Notes :
(1) Valid provided that electrodes of the case ard kept at ambient temperature.
(2) Measured under thermal equilibrium and DC (I
ZT
) test conditions.
(3) 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.
