Thermal Resistance Junction to Lead, Axial, L=3/8” Junction to End Cap, SM / SMS NOTES: 1/ For ordering information, price, and availability- contact factory. 2/ Screening Based on MIL-PRF-19500. Screening Flows Available on Request. 3/ SSDI standard marking consists of a contrasting color cathode band and Zxxx where the xxx is the nominal Vz voltage. The full part number information is included on packaging labels. 4/ 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. 5/ 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. 6/ Izsm values indicated 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. NOTE: All specifications are subject to change without notification. SCD's for these devices should be reviewed by SSDI prior to release.
