Notes: 5. For a device surface mounted on minimum recommended pad layout FR-4 PCB with single sided 1oz copper, in still air conditions; the device is

measured when operating in a steady-state condition. The entire exposed collector pad is attached to the heatsink.

6. Same as note 5, except device is surface mounted on 25mm X 25mm collector pad heatsink with 1oz copper.

7. Thermal resistance from junction to solder-point (at the end of the collector lead).

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