RJA 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. RJC is guaranteed by design while RCA is determined by the user's board design. a) b) RJA is 100C/W (steady state) when mounted on a 1 inch copper pad on FR-4. RJA is 125C/W (steady state) when mounted on a minimum copper pad on FR-4. 2. Pulse Test: Pulse Width < 300s, Duty Cycle < 2.0% FDW2508P Rev.
