Notes:
5. For the device mounted on minimum recommended pad layout FR4 PCB with high coverage of single sided 1oz copper in still air condition.
6. Same as Note 5, expect the device is mounted on 15mm X 15mm X 1.6mm FR4 PCB.
7. Thermal resistance from junction to solder-point (at the end of the collector lead).
