Notes:

6. For a device surface mounted on 25mm X 25mm FR4 PCB with high coverage of single sided 1 oz copper, in still air conditions; device measured when

operating in steady state condition.

7. Same as note (6), except the device is mounted on 50mm X 50mm single sided 2oz weight copper.

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

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