1) For calculation of heatsink please see values below Note.
|
|
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
Example:
Ambient temperature 25°C, Power Rating: 10W
1) P = DT / [RTH(j-c) + RTH (c-a)]
2) DT = 175°C - 25°C = 150K
3) [RTH(j-c) + RTH (c-a)] = DT / P = 150K / 10W = 15K/W4) RTH (c-a) = 15K/W - 1,5K/W = 13,5K/W
