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 8 mm from case are kept at ambient temperature. 3) Measured under thermal equilibrium and DC test conditions. 4) The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current IZT. 5) Tested with pulses tp = 20 ms.
