NOTES:
1/ For ordering information, price, and availability- contact factory.
2/ Screening Based on MIL-PRF-19500. Screening Flows Available
on Request.
3/ SSDI standard marking consists of a contrasting color cathode
band and Zxxx where the xxx is the nominal Vz voltage. The full
part number information is included on packaging labels.
4/ All zener voltages are measured with an automated test set
using a 35 msec test time. Longer or shorter test time will have
a corresponding effect on the measured value due to heating
effects.
5/ Zener impedance is derived from the AC voltage divided by the
AC current with RMS value of 10% of DC zener test current
superimposed on the test current.
6/ Izsm values indicated are for a peak sinusoidal surge current of
8.3 msec duration, non-repetitive. The 8.3 msec square pulse
rating is 71% of the value shown.
