Notes:
6. For the device mounted on minimum recommended pad layout FR4 PCB with high coverage of single sided 1oz copper in still air condition; the device is
measured when operating in a steady-state condition.
7. Same as note (6), except the device is mounted on 15mm x 15mm FR4 PCB.
8. Thermal resistance from junction to solder-point (at the end of the leads).
