Notes: 1: RθJA is determined with the device mounted on a 1in2 oz. copper pad on a 1.5 x 1.5 in. board of FR-4 material. RθJC is guaranteed by design while RθJA is determined by the user's board design. (a) MOSFET RθJA = 86oC/W when mounted on a 1in2 pad of 2 oz copper, 1.5” x 1.5” x 0.062” thick PCB. (b) MOSFET RθJA = 173oC/W when mounted on a minimum pad of 2 oz copper. (c) Schottky RθJA = 86oC/W when mounted on a 1in2 pad of 2 oz copper, 1.5” x 1.5” x 0.062” thick PCB. (d) Schottky RθJA = 140oC/W when mounted on a minimum pad of 2 oz copper.
