Popis: The described method is valid for arbitrary wave forms of the constant pulse current and for all diode, transistor and thyristor family devices whose thermal circuit can be modelled electrically by the serial connection of resistor-capacitor RC-pairs and whose forward characteristic can be approximated by slope resistance and threshold voltage. Temperature dependence of the device's thermal circuit parameters and temperature dependence of the forward characteristic parameters were not taken into consideration. The method enables an estimate to be made of the influence of current amplitude on the value of thermal impedance for pulse current.
