Operating and Storage Temperature Range
Notes: 4. For a dual device surface mounted on 28mm x 28mm (8cm2) 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 collector pads connected to each half.
5. Same as note (4), except the device is measured at t <5 sec.
6. Same as note (4), except the device is surface mounted on 31mm x 31mm (10cm
7. For a dual device with one active die.
8. For dual device with 2 active die running at equal power.
9. Thermal resistance from junction to solder-point (at the end of the collector lead).
