Prefix “SZ3G” indicates glass cylindrical shape. Replace with “SZ3F” for frit glass shape. “SM” for surface mount round tab.
“SMS” for square tab.
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.
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.
Ratings based on maximum zener voltage of individual units (leaded units). Multiply by 1.3 for SM and SMS devices.
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.
SSDI standard marking consists of a contrasting color cathode dot or band. Part number information is included on packaging labels. SM package not available
with frit glass shape.
Screening based on MIL-PRF-19500. Screening flows available on request.
For ordering information, price, operating curves, and availability- Contact Factory.
NOTE:
All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
