Abstract
The new CoolMOS C3 generation combines extremely high on state conductivity with ultra fast switching speed at full pulse current capability. In many applications the outstanding switching performance of the CoolMOS can't be utilized due to the dynamic behaviour of the diode. For this reason a whole family of SiC-diodes have been developed to get the ideal matched pair of switch and ultra fast diodes. Silicon carbide switching devices exhibit superior properties compared to the silicon devices. Low specific on-resistance for high breakdown voltages is believed to be the most outstanding feature of SiC power switching devices. However, there are additional advantages making SiC devices attractive for the system designer. Fast switching and fast recovery of the built-in diode as well as short circuit capability (1ms) of vertical VJFETs is in many application of great importance. The new IGBT and EMCON-diode family covers the whole power rating from 1A les 1 les 3600 A and 600 V les VB1 les 6500 V. Especially the FS-NPT-IGBT-technology shows an outstanding ruggedness behaviour e.g. temperature stability, latch up free, short circuit capability is easy in paralleling but dependent on the voltage rating certain requirements have to be considered. While the switching speed of the low voltage devices (600 V, 1200 V, 1700 V) is almost unlimited special care has to be taken by the high voltage devices

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
