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.

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.
