Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper mounting surface of the drain pins. RθJL is guaranteed by design, while RθJA is determined by the board design. The maximum rating presented here is based on mounting on a 1 in 2 pad of 2oz copper. 2
