Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
2. Thermal resistance test board
Size: 1.6 mm x 76.2 mm x 114.3 mm (1S0P) JEDEC Standard: JESD51−3, JESD51−7.
3. Assume no ambient airflow.
4. TJMAX = 150°C; ratings apply to ambient temperature at 25°C.
5. Power dissipation calculation: PD = (TJ − TA) / RθJA.
