2. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for
extended periods, may reduce device reliability. Unless otherwise stated voltages specified are relative to the ANODE pin.
3. TJ, max =150°C.
4. Ratings apply to ambient temperature at 25°C.
