Abstract :
An electrothermal model was developed for the built-in VDMOSFET diode. This model calculates the static and dynamic characteristics of the diode by taking into account the heating effect due to the diode´s own losses and those of the VDMOSFET. The model´s parameters were calculated from the catalog data, known relations from literature and the curve of the measured transient thermal impedance for constant current. The accuracy of the model in a simulation of the temperature dependence of the forward characteristic and the time course of silicon temperature was checked with a MEDICI two-dimensional device simulator.
