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 corres ponding 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 superimpos ed 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.
