(1)

The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the

ambient temperature, TA. The maximum available power dissipation at any temperature is PD = (TJMAX − TA) / θJA or the 25°C PdMAX,

whichever is less.

(2)

Maximum power dissipation is defined by the package characteristics. Operating the part near the maximum power dissipation may

cause the part to operate outside specified limits.
