Exceeding the absolute maximum ratings may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
P_D(max) = (T_J(max) – T_A) ÷ θ_JA, where θ_JA depends upon the printed circuit layout. See “Applications Information.”
