NOTES:
1/
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.
2/
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.
3/
Ratings based on maximum zener voltage of individual units (leaded units).
4/
Figures shown 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.
5/
SSDI standard marking consists of a contrasting color cathode dot or band. Part number information is included on packaging labels.
6/
For Ordering Information, Price, and Availability- Contact Factory.
7/
Screening based on MIL-PRF-19500. Screening flows available on request.
8/
Voltages are shown for 5% tolerance devices.
