Web24 mei 2024 · A silicon power transistor is operated with a heat sink (θSA = 1.5°C/W). The transistor, rated at 150 W (25°C), has θJC = 0.5°C/W, and the mounting insulation has θCS = 0.6 ºC/W. What is the maximum power that can be dissipated if the ambient temperature is 50°C and TJmax = 200°C? WebWith a maximum duty factor of 94%, a 30A load current, and a 4.13mΩ maximum R DS (ON), these paralleled MOSFETs dissipate about 3.5W. Supplied with 2in² of copper to dissipate that power, the overall Θ JA should be about 18°C/W. Note that this thermal resistance value is taken from the MOSFET data sheet.
