¹⁾The dynamic resistance is derived from the 60 Hz AC voltage which results when an AC current having an RMS value equal to 10% of

the Zener Current (I_ZTor I_ZK) is superimposed on I_ZTor I_ZK. Dynamic resistance is measured at two points to insure a sharp knee on the

breakdown curve and to eliminate unstable units.

²⁾Valid provided that electrodes are kept at ambient temperature.

³⁾Tested with pulses tp = 20 ms.

⁴⁾The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or

equivalent sine wave pulse of 1/120 second duration superimposed on the test current I_ZT
