Abstract :
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 transient simulations of the device with compact thermal models.
