Notes :
1. R θ JA is determined with the device mounted on a 1 in 2 pad 2 oz copper pad on a 1.5 x 1.5 in. board of FR-4 material. R θ JC is guaranteed by design while R θ CA is determined by
the user's board design.
53 °C/W when mounted on a
1 in 2 pad of 2 oz copper
2. Pulse Test: Pulse Width < 300 μ s, Duty cycle < 2.0%.
3.Starting T J = 25 ° C; N-ch: L = 0.3 mH, I AS = 24 A, V DD = 36 V, V GS = 10 V.
