RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RθJC is guaranteed by design while RθCA is determined by the user's board design. a) RθJA is 96°C/W (steady state) when mounted on a 1 inch² copper pad on FR-4. b) RθJA is 208°C/W (steady state) when mounted on a minimum copper pad on FR-4. 2.
