Notes :
(1) The Zener impedance is derived from the 1 kHz 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 insur
a sharp knee on the breakdown curve and to eliminate unstable units
(2) Valid provided that leads at a distance of 10 mm from case are kept at ambient temperature
(3) Standard Zener voltage tolerance is
±
10%. Add suffix “B” for
±
5% tolerance.
