The scope of applicability of DPL model to the heat transfer in electron devices

This paper presents the scope of applicability of Dual-Phase-Lag model in modern electronic structures. Moreover, the investigation of obligatory application of this model, instead of the classical approach based on Fourier-Kirchhoff model, to heat transfer modeling is included. Furthermore, the modified Fourier-Kirchhoff thermal model, containing the special time lag parameter, is also taken into consideration. In order to obtain the mentioned scope of applicability both analyzed thermal model, the three different classical power transistors i.e. unipolar, bipolar and insulated gate bipolar transistors (IGBT), have been considered. The received simulation results have been carefully compared and analyzed in detail.
