Notes:
1. Repetitive Rating : Pulse width limited by maximum junction temperature
2. L = 7.9mH, IAS = 10A, VDD = 50V, RG = 25 Ω, Starting TJ = 25°C
3. ISD ≤ 10A, di/dt ≤ 300A/µs, VDD ≤ BVDSS, Starting TJ = 25°C
4. Pulse Test : Pulse width ≤ 300µs, Duty cycle ≤ 2%
5. Essentially independent of operating temperature
