Notes:
(1)The Zener impedance is derived from the 1kHz Ac voltage which results when an AC current having an RMS value equal to 10%
of the Zener current (1 ZT) is superimposed on1 ZT Zener impedance is measured at two points to insure a sharp knee on the
breakdown curve and to eliminate unstable units.
(2)valid provided that leads are kept at ambient temperature at a distance of 8 mm from case.
(3)Measured with device junction in thermal equilibrium.
