Notes:

5. For a device mounted with the exposed collector pad on minimum recommended pad layout (MRP) 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 with the exposed collector pad on 15mm x 15mm 1oz copper.

7. Same as Note 5, except the device is mounted with the exposed collector pad on 25mm x 25mm 1oz copper.

8. Same as Note 5, except the device is mounted with the exposed collector pad on 50mm x 50mm 1oz copper.

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

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