Intrinsic turn-on time is negligible (turn-on is dominated by LS+LD)
Notes:
 Calculated continuous current based on maximum allowable junction
temperature. Package limitation current is 75A
 Repetitive rating; pulse width limited by max. junction
temperature.
 Limited by TJmax, starting TJ = 25°C, L = 0.095mH
RG = 25â¦, IAS = 50A, VGS =10V. Part not recommended for use
above this value.
 Pulse width ⤠400µs; duty cycle ⤠2%.
Â
Rθ is measured at TJ approximately 90°C
