For a through-hole device mounted at the seating plane (2.5mm lead length) with the collector lead on 25mm X 25mm 1oz weight copper that is on a single-sided FR4 PCB device is measured under still air conditions whilst operating in a steady-state. 6. Same as note (5), except the device is mounted on minimum recommended pad layout with 12mm lead length from the bottom of package to the board. 7. Thermal resistance from junction to solder-point at the seating plane (2.5mm from the bottom of package along the collector lead). 8. Refer to JEDEC specification JESD22-A114 and JESD22-A115.
