【Abstract】 This article suggests a mathematical model of heat situation on the case of high power transistor. The formulae for calculating its temperature distribution, heat-flow rate and heat resistance are deduced from solving this model. They may be used for heat design and heat stress analysis of case of high power transistor.更多还原
