WebOct 8, 2024 · A silicon carbide (SiC) JFET is a junction-based normally-on transistor type that offers the lowest on-resistance R DS(on) per unit area and is a robust device. JFETs are less prone to failure compared to traditional MOSFET devices and suit circuit breaker and current limiting applications. For example, if you bias the gate of a JFET with a 1 mA current, and … Web供应SiC碳化硅。2.4 SiC在炉料中的应用 碳化硅是一种硅基生核剂，熔点达2700℃，在铁液中不熔化，按SiC+Fe=FeSi+C（非平衡石墨）熔融于铁液，式中SiC里的Si与Fe结合，余下的C即非平衡石墨，作为石墨析出的核心[5]。并且碳化硅还是很好的脱氧剂，灰铸铁、球墨铸铁和可锻铸铁都是通过SiC+FeO=Si+Fe+CO这个 ...
