More companies are seriously looking at using silicon carbide devices for their newest designs (you can a paper on a comparison of SiC manufacturers at: http://www2.electronicproducts.com/SiC_demystified_choosing_the_right_manufacturer_for_your_design-article-wcpo_21may2012-html.aspx ).

For your newest designs what would be the most important criteria? Do you most need:
