* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Thermal resistance junction ambient for IC with heat dissipater is calculated by formula:
Rth ja = Rth jc + Rth ca
Rth jc - thermal resistance junction case, oC /W.
Application circuit and heat dissipater have to provide TJ  125 oС.
Maximum power Ptot, Вт, dissipated by IC for TA, is calculated by formula:
Ptot = (125 - TA) / Rth ja
125 – maximum permitable operating junction temperature, ОС
