This paper discusses on the practical example of a power diode attached to a heat sink the problem of heat transfer coefficient temperature dependence and its importance for free convection cooled electronic systems. The average values of this coefficient are estimated from multiple measurements of device cooling curves performed for different device heating currents. These values are used then for...
This paper discusses on the practical example of a power diode the problem of the heat transfer coefficient dependence on temperature and its impact on device junction temperature when the thermal resistance is dominated by the heat exchange with ambient, e.g. for the free convection cooling. The proper determination of this dependence is crucial for the accurate computation of the device operating...
