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/ 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, Operating Curves, and Availability- Contact Factory. 5/ Screened to MIL-PRF-19500. 6/ Suffix "L" for Axial, "SM" for Round Tab Surface Mount, and "SMS" for Square Tab Surface Mount. 7/ Temperature Range of Coefficient is -55C to +150C. 8/ Figures shown are for a peak sinusoidal surge current of 8.3 msec duration, non-repetitive. The 8.3 msec square wave pulse rating is 71% of the value shown.
NOTE: All specifications are subject to change without notification. SCD's for these devices should be reviewed by SSDI prior to release.
