(2) The junction-to-ambient thermal resistance, θJA, applies to devices soldered directly to a 100 mm x 100 mm, 6-layer PCB with 1 oz. copper and natural convection cooling. Additional airflow reduces θJA. (3) The junction-to-ambient thermal resistance, θJA, applies to devices soldered directly to a 100 mm x 100 mm, 6-layer PCB with 1 oz. copper and 100 LFM forced air cooling. Additional airflow reduces θJA. (4) The junction-to-top characterization parameter, ψJT, estimates the junction temperature, TJ, of a device in a real system, using a procedure described in JESD51-2A (sections 6 and 7). TJ = ψJT * Pdis + TT; where Pdis is the power dissipated in the device and TT is the temperature of the top of the device. (5) The junction-to-board characterization parameter, ψJB, estimates the junction temperature, TJ, of a device in a real system, using a procedure described in JESD51-2A (sections 6 and 7). TJ = ψJB * Pdis + TB; where Pdis is the power dissipated in the device and TB is the temperature of the board 1mm from the device.
