Substrate
Heat spreading occurs when heat flows into a material layer of increased
cross-sectional area. It is adequate to assume that spreading occurs at a
45° angle.
The total thermal resistance is calculated by summing the thermal
resistances of each material in the thermal path between the device and
hybrid case.
The total thermal resistance RT (see figure 2) between the heat source
(die) to the hybrid case is the Theta Junction to Case (Theta JC) in°C/W.
• Theta junction to case (Theta JC) for this product is 30°C/W.
• Theta case to ambient (Theta CA) for this part is 100°C/W.
• Theta Junction to ambient (Theta JA) is 130°C/W.
