Notes:
(1) The Zener Impedance is derived from the 1 KH AC voltage which results when an AC current having an RMS value equal to 10% of the
Z
Zener current (I ) is superimposed on I . Zener Impedance is measured at two points to insure a sharp knee on the breakdown curve
ZT
ZT
and to eliminate unstable units.
(2) Valid provided that leads at a distance of 3/8” from case are kept at 25°C ambient temperature.
(3) Measured with device junction in thermal equilibrium.
