Notes:
1. The Zener impedance is derived from the 1 KHz 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.
2. Valid provided that leads at a distance of 3/8" from case are kept at ambient temperature.
3. Measured with device junction in thermal equilibrium.
