Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Pulse width limited by safe operating area.
3. L=0.13mH, IAS=82A, VDD=38V, RG=25 Ω, Starting TJ = 25°C
4. ISD≤82A, di/dt≤310A/μs, VDD ≤ BVDSS, Starting TJ = 25°C
5. Repetitive rating; pulse width limited by max. junction temperature.
6. Calculated continuous current based on maximum allowable junction temperature. Package limitation
current is 75A.
