Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formula:
TJ = TA + (PD) x (220°C/W).
Note 3: Y: Year of wafer manufacturing W: Week of wafer manufacturing
Note 4: Thermal Resistance is specified with approximately 1 square of 1 oz copper.
