Avalanche Capability of Unipolar SiC Diodes: A Feature for Ruggedness and Reliability Improvement
Bibliographic record
Abstract
SiC Diodes in the 300 to 1200V range have steadily increased their market penetration in the last 7 years. Especially the 600V SiC diodes are a nearly mandatory device for further increase of power density in modern switch mode power supplies. Those devices entered the market from the high end side due to the still significant higher costs in comparison with conventional fast Si diodes. On the other hand, these high end markets like server or telecom power supplies also require very high reliability of the devices used. In previous papers we showed, that Merged-PN-Schottky (MPS) diodes can be designed for avalanche ruggedness [1,2]. In this paper we will describe, how this feature supports overall reliability improvement. Addditionally, we will show, how a conventional SiC Schottky diode without MPS structure can be modified in order to achieve stable avalanche breakdown in combination with strong reliability improvement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
