3.2. Application Notes
The thermal resistance of the DFN8L package can be enhanced by using the bottom pad as
heat sinks.
In order to lower the thermal resistance, vias should be placed below the Drain and Source
pads. These vias should connect to big enough heat sinks within the PCB. This will also be
beneficial for the ohmic resistance of the traces.
