Notes:
1.
R
θJA
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. R
θJC
is guaranteed by design while R
θCA
is determined by the user's board design.
a) R
θJA
is 125°C/W (steady state) when mounted on a 1 inch² copper pad on FR-4.
b) R
θJA
is 208°C/W (steady state) when mounted on a minimum copper pad on FR-4.
