Notes:

1: RθJA 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. RθJC is guaranteed by design while RθJA is determined by the user’s board design.

a) 50°C/W when mounted on a 1in2 pad of 2 oz copper

b) 125°C/W when mounted on a minimum pad .

Scale 1:1 on letter size paper

2: Pulse Test: Pulse Width < 300 us, Duty Cycle < 2.0%.

3: Starting TJ = 25°C, L = 3mH, IAS = 10A, VDD = 40V, VGS = 10V.
