1. Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.

2. T_Jis calculated from the ambient temperature T_Aand power dissipation P_Daccording to the following formula: T_J= T_A+ P_D· _JA.

3. Thermal Resistance is specified with approximately 1 square inch of 1 oz. copper.

4. Thermal Resistance Junction-to-Case is measured on the top of the package per JEDEC standards.
