1. Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
2. TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula: TJ = TA + PD x JA.
3. Thermal Resistance is specified with approximately 1 square inch of 1 oz. copper.
