This paper focuses on the modelling of a SiC-JFET. The novelty aspect is the dependence on temperature. An accurate model has been used in a previous work and an identification procedure for the main model parameters has been demonstrated. Readers have asked for a more advanced SiC JFET temperature-dependent model. A limitation of the current model versus temperature is verified and explained in order to introduce the necessity of a new temperature dependence model. A more advanced model is then considered and a comparative study between experiment and simulation of the device is established. The characteristics of three SiC JFETs devices are considered from experimental and simulation point-of-view. Simulations results clearly replicate the experimental data at different temperatures and a new validity approach, namely validity maps, is proposed. Validity domains are discussed.
