PRODUCTION DATA
Equation 1 shows the thermal calculation.

where:
For a device under operation at a given ambient air temperature (TA), use Equation 2 to calculate the junction temperature (TJ).

where:
Use Equation 3 to calculate the rise in junction temperature because of power dissipation.

For a given maximum junction temperature (TJmax), use Equation 4 to calculate the maximum ambient air temperature (TAmax) at which the device can operate.
