We propose the use of conventional JFIIT switches as specific devices (CCLD). SiC-JFETs electro-thermal static characterization are reported. Electro-thermal simulation have been carried out to estimate dynamic behaviour of both discret JFETs used as current limiting devices and laboratory specific devices. Surge capabilities have been investigated. It can be concluded that SiC-JFETs might be used not only as switches but also as limiting devices for the safety of both consumer electronics application as well as for power distribution.
