†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 voltage created when AC current with RMS value of 10% of DC zener test current is superimposed on the test current.

ŧ Graphs shown are for 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.
