1) For calculation of heatsink please see values below Note.
Calculation of heatsink
P = DT / [RTH(j-c) + RTH(c-a)]
P = Expressed in W DT = Difference between maximum working temperature (155°C) and room temperature
RTH(j-c) = Thermal resistance of the component
RTH(c-a) = Thermal resistance of the heatsink and quality of fastening device
