Notes: 5. For the device mounted on minimum recommended pad layout 1oz copper that is on a single-sided 1.6mm FR4 PCB; device is measured under still air conditions whilst operating in steady state condition. The entire exposed collector pad is attached to the heatsink. 

6. Same as Note 5, except the exposed collector pad is mounted on 25mm x 25mm 2oz copper. 

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

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