Notes:

6. For a device mounted on minimum recommended pad layout 1oz copper that is on a single-sided FR-4 PCB; device is measured under still air

conditions whilst operating in a steady-state.

7. Same as Note 6, except the device is mounted on 15mm x 15mm 1oz copper.

8. Thermal resistance from junction to solder-point (at the end of the leads).

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