NOTES:
1/ For ordering information, price, and availability – contact factory.
2/ Screening based on MIL-PRF-19500. Screening flows available on request. X-Ray shall be performed in lieu of Precap Inspection – Consult factory.
3/ Consult factory for package outlines.
4/ All 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/ Exponential waveform i.a.w. IEC60-1 10/1000 uS pulse
NOTE:
All specifications are subject to change without notification.
SCD's for these devices should be reviewed by SSDI prior to release.
