Notes:
 Calculated continuous current based on maximum allowable junction
temperature. Package limitation current is 75A
‚ Repetitive rating; pulse width limited by max. junction
temperature.
ƒ Limited by TJmax, starting TJ = 25°C, L = 0.096mH
RG = 25Ω, IAS = 50A, VGS =10V. Part not recommended for use
above this value.
„ Pulse width ≤ 400µs; duty cycle ≤ 2%.
… Rθ is measured at TJ approximately 90°C
