Notes: 5. For a device surface mounted on 15mm x 15mm x 0.6mm FR4 PCB with high coverage of single sided 1 oz copper, in still air conditions; the device is
measured when operating in steady state condition.
6. Same as note (5), except the device is mounted on 40mm x 40mm x 1.6mm FR4 PCB.
7. Thermal resistance from junction to solder-point (on the exposed collector pad).
