Notes: 6. For a device mounted with the exposed collector pad on 25mm x 25mm 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. Same as note (6), except the device is measured at t ≤ 5 sec.

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.
