Note 1. Measured with device junction in thermal equilibrium.
Note 2. 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 (IZT) is superimposed on IZT. Zener
impedance is measured at two points to insure a sharp knee on the breakdown curve and
to eliminate unstable units.
Note 3. valid provided that leads at a distance of 3/8” from case are kept at ambient temperature.
