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.
NOTE:
All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
