Notes:
1. Measured under thermal equilibrium and DC (I
ZT
) test conditions.
2. 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.
