Notes:
2. Measured under thermal equilibrium and dc (I
ZT
) test conditions.
3. The Zener impedance is derived from the 60 Hz 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.
