Notes:
(1)The Zener impedance is derived from the 1KHZ AC current having an RMS value equl 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 electrodes at a distance of 10mm from case are kept at ambient temperature
(3)Measured under thermal equilibrium and DC test conditions
