Notes:

6. For a device mounted with the collector lead on 15mm x 15mm 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.

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.
