Specify 10% voltage tolerance by changing first numeral of type number from 7 to 8 or from 1 to 2. All zener voltages are measured with an automated test set using a 35 ms test time. Longer or shorter test times will have a corresponding effect on the measured value due to heating effects. Zener impedance is derived from the 60-cylce AC voltage created when AC current with RMS value of 10% of DC zener test current is superimposed on the test current. Maximum current based on 3 watt rating, Figures shown are for a peak sinusoidal surge current of 8.3 ms duration using 60 cycle AC. The 8.3 ms square pulse is 71% of the value shown.
