1)The Zener Impedance is derived from the 60HZ AC voltage which results when an AC current having RMS value equal to 10% of the Zener Current(IZT or IZK) is superimpose on IZ or Izk. Zener Impedance is measured at two pointts to insure a sharp knee on the breadown curve and to eliminate unstable units. 

2)Valid povided that leads at a distanc of 8 mm from case are kept at kept at ambient temperature.
