A transistor junction has a total power loss of 25 W, and the junction to case thermal
Question:
A transistor junction has a total power loss of 25 W, and the junction to case thermal resistance is 0.9°C/W. The case is mounted on heat sink #9 with a 50-μm-thick mica insulation with thermal grease resulting in the case to heat sink thermal resistance of 0.5°C/W. The air temperature inside the converter cabinet can be as high as 55°C. Determine the maximum junction temperature in this device.
