Notes:
2. Measured under thermal equilibrium and dc (I
ZT
) test conditions.
3. The Zener impedance is deriv
ed from the 60 Hz ac v
oltage which results when an ac c
urrent having an
rms value equal to
10% of the Zener curr
ent (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 break
down curve and to eliminate unstable units.
