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 (IZT or IZK) is superimposed on IZT or IZK. 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 leads at a distance of 8 mm from case 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 IZT.
