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. 8/ 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. DATA SHEET #: Z00008G DOC
