Notes: 5. For a device surface mounted on 52mm x 52mm x 1.6mm FR4 PCB with high coverage of single sided 2oz copper, in still air conditions; the device is
measured when operating in a steady-state condition.
6. Same as note (5), except the device is surface mounted on 25mm x 25mm with 1oz copper.
7. Thermal resistance from junction to solder-point (at the end of the collector lead).
