Thermal Characteristics
The heat transfer model in a hybrid package is described in figure 1.
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.
RT = R1 + R2 + R3 + R4 + R5
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.
Maximum power dissipation PD for this package at 25°C is:
• PD(max) = (TJ (max) – TA)/Theta JA
• With TJ = 175°C (Maximum junction temperature of die)
• PD(max) = (175 – 25)/130 = 1.15W
