Notes: 10. For a dual device surface mounted on 28mm x 28mm (8cm
2
) FR4 PCB with high coverage of single sided 2 oz copper, in still air conditions; the device
is measured when operating in a steady-state condition. The heatsink is split in half with the exposed cathode and collector pads connected to each half.
11. Same as note (10), except the device is measured at t <5 sec.
12. Same as note (10), except the device is surface mounted on 31mm x 31mm (10cm
2
) FR4 PCB with high coverage of single sided 1oz copper.
13. For a dual device with one active die.
14. For dual device with 2 active die running at equal power.
15. Thermal resistance from junction to solder-point (on the exposed cathode pad).
