(1) Power rating is determined with a junction temperature of 125°C. This is the point where distortion starts to substantially increase and
long-term reliability starts to be reduced. Thermal management of the final PCB should strive to keep the junction temperature at or
below 125°C for best performance and reliability.
(2) This data was taken with the JEDEC High-K test PCB. For the JEDEC low-K test PCB, the θ_JA is 125.8°C.
