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. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low
frequency and duty cycles to keep initial TJ=25°C.
