confines of the basic footprint. The drain copper area is
0.0019 sq. in. (or 1.22 sq. mm). This will assist the power
dissipation path away from the device (through the copper
leadframe) and into the board and exterior chassis (if
applicable) for the single device. The addition of a further
copper area and/or the addition of vias to other board layers
will enhance the performance still further.
