NOTES:
†
Suffix “L” for axial lead, “SM” for surface mount Round Tab. “SMS” for Square Tab.
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) Ratings based on maximum zener voltage of individual units (leaded units). Multiply by 1.3 for SM and SMS devices.
4) Figures shown are for a peak sinusoldal surge current of 8.3 msec duration, non-repetitive. The 8.3 msec square pluse 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.
For optional high reliability screening or higher nominal zener voltages, consult SSDI MARKETING Department.
NOTE:
All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
