Notes:
1) Valid provided that leads at a distance of 8 mm from case are
kept at ambient temperature.
2) Measured under thermal equilibrium and DC test conditions.
3) The rating listed in the electrical characteristics table is
maximum peak, non-repetitive, reverse surge current of 1/2 square
wave or equiv-alent sine wave pulse of 1/120 second duration
superimposed on the test current, IZT ,per JEDEC registration;
however, actual device capability is as described in Fiure 5 of the
General Data-DO-41 Glass.
4) Tested with pulses tp = 20 ms.
5) VF(Max)=1.20V@ IF=200mA
*Measure under thermal equilibrium and DC current test
conditions(TA=25℃)
Tolerance on 1N47..A Vz value: ±5%.
