J AS DD DD 3: R is the sum of the junction-to-case and case-to-ambient thermal resistance, where the case thermal reference is defined as the solder JA mounting surface of the drain pins. R is guaranteed by design, while R is determined by the board design. The maximum rating JC JA 2 presented here is based on mounting on a 1 in pad of 2oz copper.
