Specify 20% voltage tolerance by changing first numeral of type number from 7 to 9 or from 1 to 3. 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-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.
