Specify 20% voltage tolerance by changing first numeral of type number from 8 to 9.
Specify 5% voltage tolerance by changing first numeral of type number from 8 to 7.
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-cycle 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 rating is 71% of the
value shown.
