Notes: 5. For a device mounted with the exposed collector pad on 15mm x 15mm 1oz copper that is on a single-sided 1.6mm FR4 PCB; device is measured under still air conditions whilst operating in a steady-state. 

6. Same as Note 5, except the device is mounted on 25mm x 25mm 1oz copper. 

7. Same as Note 5, except the device is mounted on 50mm x 50mm 1oz copper. 

8. Thermal resistance from junction to solder-point (on the exposed collector pad). 

9. Thermal resistance from junction to the top of the case. 

10. Refer to JEDEC specification JESD22-A114 and JESD22-A115.
