The following section provides a heat sink selection example using one of the commercially available heat
sinks.
19.2.3 Heat Sink Selection Example
For preliminary heat sink sizing, the die-junction temperature can be expressed as follows:
Tj = Ti + Tr + (RθJC + Rθint + Rθsa) × Pd
where:
Tj is the die-junction temperature
Ti is the inlet cabinet ambient temperature
Tr is the air temperature rise within the computer cabinet
RθJC is the junction-to-case thermal resistance
Rθint is the adhesive or interface material thermal resistance
Rθsa is the heat sink base-to-ambient thermal resistance
Pd is the power dissipated by the device
During operation, the die-junction temperatures (Tj) should be maintained less than the value specified in
Table 2. The temperature of air cooling the component greatly depends on the ambient inlet air temperature
and the air temperature rise within the electronic cabinet. An electronic cabinet inlet-air temperature (Ti)
may range from 30
to 40 C. The air temperature rise within a cabinet (Tr) may be in the range of 5 to
10 C. The thermal resistance of the thermal interface material (Rθint) is typically about 0.2 C/W. For
