Notes:
1: RθJA is determined with the device mounted on a 1in2 pad 2 oz copper pad on a 1.5 x 1.5 in. board of FR-4 material. RθJC is guaranteed by design while RθCA is determined by
the user's board design.
b. 135°C/W when mounted on a
minimum pad of 2 oz copper
a. 60°C/W when mounted on
a 1 in2 pad of 2 oz copper
2: Pulse Test: Pulse Width < 300µs, Duty cycle < 2.0%.
