WebAug 26, 2010 · Abstract. The baseline temperature in an electronic system is a very important parameter for thermal design and must be carefully considered. But the term ambient temperature has developed a lot of ambiguity in its usage as well as its value. System and component designers can greatly improve the accuracy of their thermal … Power semiconductor devices have a maximum power dissipation rating usually quoted at a case temperature of 25 °C (77 °F). The datasheet for the device also includes a derating curve which indicates how much a device will dissipate without getting damaged at any given case temperature, and this must be taken into account while designing a system. As can be seen from the derating curve image for a hypothetical bipolar junction transistor, the d…
