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. Device mounted on FR-4 substrate PC board with minimum recommended pad layout in a still air

environment @ TA=25°C. The value in any given application depends on the user's specific board design.

3. Repetitive rating, pulse width limited by junction temperature.

4. IAR and EAR rating are based on low frequency and duty cycles to keep TJ=25°C
