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.
