NOTES:  
1/ All zener voltages are measured with an automated test set using a 10 - 50 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/ SSDI standard marking consists of a contrasting color cathode dot or band. Part number information is included on packaging labels.  
4/ For Ordering Information, Price, and Availability- Contact Factory.  
5/ Screening based on MIL-PRF-19500. Screening flows available on request.  
6/ Suffix “SMS” for Square Tab Surface Mount.  
7/ For tighter tolerances, consult the factory.  
8/ Figures shown are for a peak sinusoidal surge current of 8.3 msec duration, repeated a maximum of 1 surge per minute.  
9/ Contact factory for availability  
NOTE: All specifications are subject to change without notification.  
SCD's for these devices should be reviewed by SSDI prior to release.
