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.
