(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.
