Notes: 6. For a device mounted with the collector lead on 25mm x 25mm 1oz copper that is on a single-sided 1.6mm FR4 PCB; the device is measured
under still air conditions whilst operating in a steady-state. Two active dice running at equal power with heatsink split 50% to each collector.
7. Same as Note 6, except the device is measured at t < 5 seconds.
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.
