Notes: 1.
Rθ 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 JA the drain pins. Rθ is guaranteed by design while R is determined by the user's board design. ` JC θCA a) 78°C/W when b) 125°C/W when c) 135°C/W when mounted on a mounted on a mounted on a 0.5in2 pad of 2 0.02 in2 pad of minimum pad. oz copper 2 oz copper Scale 1 : 1 on letter size paper
