We know, TJ-TA=HPD
TJ=TA+HPD=27+8*3=51°C.
TJ=TA+HPD=27+8*3=51°C.

Thermal resistance for a transistor is typically measured in degrees Celsius per watt (°C/W). It represents the ability of the transistor to dissipate heat and maintain a safe operating temperature.
In this case, the thermal resistance of the given transistor is 8 °C/W. This means that for every watt of power dissipated by the transistor, the temperature of the transistor will increase by 8 degrees Celsius.
A lower thermal resistance indicates better heat dissipation capabilities, allowing the transistor to operate at lower temperatures. Higher thermal resistance can lead to increased temperatures, potentially affecting the performance and reliability of the transistor.
