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 or IZK)

is superimposed on IZT or IZK. 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 10 mm from case are kept at ambient temperature (3) Measured with device junction in thermal equilibrium
