Notes: RÓ¨JA is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined
at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board
design. RÓ¨JA shown below for single device operation on FR-4 PCB in still air.
