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
ZT
or I
ZK
) is superimposed on I
ZT
or 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 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 I
ZT
.
