Notes:

1. RθJAis 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. RθJCis guaranteed by design while RθCAis determined by the user's board design.

a) 78°C/W when

mounted on a 0.5in

pad of 2 oz copper

b) 125°C/W when

mounted on a 0.02

2 pad of 2 oz

copper

c) 135°C/W when mounted on a

minimum pad.
