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. 4)The rating listed in the electrical characteristics table is maximum peak,non-repetitive,reverse surge current of ½ square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current Izt. 5)Tested with pulses tp=20ms.
