Heat Sink Usage
An estimation of the chip junction temperature, T
J, can be obtained from the equation:
TJ = TA + (RθJA × PD)
where
TA = ambient temperature for the package (°C)
RθJA = junction-to-ambient thermal resistance (°C/W)
PD = power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy
estimation of thermal performance. Unfortunately, two values are in common usage: the value determined
on a single-layer board and the value obtained on a board with two planes. Which value is closer to the
application depends on the power dissipated by other components on the board. The value obtained on a
single-layer board is appropriate for the tightly packed printed-circuit board. The value obtained on the
board with the internal planes is usually appropriate if the board has low power dissipation and the
components are well separated.
When a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal
resistance and a case-to-ambient thermal resistance:
RθJA = RθJC + RθCA
where
RθJA = junction-to-ambient thermal resistance (°C/W)
RθJC = junction-to-case thermal resistance (°C/W)
RθCA = case-to-ambient thermal resistance (°C/W)
