Thermal Characteristics
CORPORATION
CRYSTAL CLOCK OSCILLATORS
1.8 to 15Vdc - 732.4Hz to 150MHz
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 heat transfer model in a hybrid package is described in figure 1.
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.
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
RT = R1 + R2 + R3 + R4 + R5
