Notes: 1. θJA is determined with the device mounted on a 1 in pad 2 oz copper pad on a 1.5 x 1.5 in. board of FR-4
material. θJC is guaranteed by design while θCA is determined by the user's board design.
a. 50°C/W when mounted on a 1 in2 pad of 2 oz copper.
b.125°C/W when mounted on a minimum pad of 2 oz copper.
2. EAS of 58mJ is based on starting TJ=25°C, L=1mH, IAS=10.8A, VDD=27V, VGS=10V. 100% test at L=0.1mH,
IAS=21A.
