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.
