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.
