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.
2. Pulse Test: Pulse Width < 300 μs, Duty cycle < 2.0%.
3. Starting TJ = 25 °C, L = 1 mH, IAS = 20 A, VDD = 27 V, VGS = 10 V
4. As an N-channel device, the negative Vgs rating is for low duty cycle pulse ocurrence only. No continuous rating is implied.
