Note 2. Zener Voltage (V
z
) is measured with junction in thermal equilibrium with 30°C stud temperature.
Note 3.The zener impedance is derived from the 60 cycle A.C. voltage, which results when an AC
current having an RMS value equal to 10% of the DC zener current (I
ZT
or I
ZK
) is superim-
posed on I
ZT
or I
ZK
. Zener impedance is measured at 2 points to insure a sharp knee on the
breakdown curve and to eliminate unstable units.
