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.
