Notes:
 Calculated continuous current based on maximum allowable junction
temperature. Package limitation current is 75A
Β‚ Repetitive rating; pulse width limited by max. junction
temperature.
Βƒ Limited by TJmax, starting TJ = 25Β°C, L = 0.096mH
RG = 25Ω, IAS = 50A, VGS =10V. Part not recommended for use
above this value.
Β„ Pulse width ≀ 400Β΅s; duty cycle ≀ 2%.
Β… RΞΈ is measured at TJ approximately 90Β°C
Static @ TJ = 25Β°C (unless otherwise specified)
