8.9 Heat sink
For SSL2108X (SO12) applications, the copper of the PCB acts as the heat sink. The
SSL2108X (SO12) uses thermal leads (pins 2, 6, 10 and 11) for enhanced heat transfer
from die to the PCB copper heat sink. The thermal lead connection can drastically reduce
thermal resistance.
Equation 1 shows the relation between the maximum allowable power dissipation P and
the thermal resistance from junction to ambient.
R th ? j – a ? = ? T j ? max ? – T amb ? ? P
Where:
R th(j-a) = thermal resistance from junction to ambient
T j(max) = maximum junction temperature
T amb = ambient temperature
P = power dissipation
