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 (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 a pulse test current.
