Notes:
4. For a device surface mounted on 31mm x 31mm (10cm
2
) FR4 PCB with high coverage of 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.
5. Same as note (4), except the device is measured at t < 5 sec.
6. Thermal resistance from junction to solder-point (at the end of the collector lead).
