NOTES: For optional high reliability screening or higher nominal voltages, consult SSDI Marketing Department.
1/
For ordering information, price, operating curves, and availability- contact factory.
2/
Screening based on MIL-PRF-19500. Screening flows available on request.
3/
All voltages are measured with an automated test set using a 35 msec test time. Longer or shorter test times will have a corresponding effect on the
measured value due to heating effects.
4/
Dynamic Impedance is derived from the AC voltage divided by the AC current with RMS value of 10% of DC test current superimposed on the test
current.
5/
Ratings based on 100°C Tab temperature (SMS and C devices); multiply by 0.6 for L devices; multiply by 0.8 for V/W devices.
6/
Pulse width (tp) is defined as the time from rated peak pulse current IPP to the point where peak pulse current decayed to 50% of rated IPP. (10μs x
1000μs waveform as defined by R.E.A.)
NOTE:
All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
