Heatsink calculation
The value of the heatsink can be calculated in a standard
way with a method based on average temperatures.
The required thermal resistance of the heatsink is
determined by the maximum die temperature of 150
°
C.
In general we recommend to design for an average die
temperature not exceeding 130
°
C.
