(1) This data was taken with a PowerPAD standard 3 inch by 3 inch, 4-layer PCB with internal ground plane connections to the PowerPAD.
(2) 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.
