Note: 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. Repetitive Rating: Pulse width limited by maximum junction temperature

3. L=5.2mH, IAS=18A, VDD=50V, RG=25Ω, Starting TJ=25°C

4. ISD ≤18A, di/dt ≤200A/μs, VDD ≤BVDSS, Starting TJ=25°C

5. Drain current limited by maximum junction temperature
