The paper considers the current trends, determining the growth requirements for system reliability electrical and electronic equipment, the main approaches to the determination of quantitative parameters and characteristics of the functional reliability of these systems and their elements. Pn article are analyzed problems in defining regulatory requirements, defining methods for measurement of static thermal resistance (STR) "transition -case" power semiconductor diods (PSD) with the purpose of the amendments and subsequent inclusion in the technical specifications for the manufacturing of devices. Proposed new method of measurement for STR "transition-case" PSD for the transition function of temperature-sensitive parameter. This method allows to determine the STR without direct measurement tempera-tours of the casing and thereby provides the possibility of end-to-end control of this parameter in the production of the SPD. The authors considered the principles of analytical description of the transition function for temperature-sensitive parameter, as the decision of: a ordinary differential equations exponential growth; a rigid system of linear differential equations. Ciples provide non-destructive testing PSD for setting the heating current. The article describes fixed issues in the technique of measurement of the thermal resistance of the В«p-n junction-caseВ» transition function of temperature-sensitive parameter and are proposed ways for their solutions. The authors also presented the results of measurements when the through-rate control STR "transition-case" for prototypes PSD with probe design for currents up to 25 A.
