** Thermal resistance junction ambient for IC with heat dissipater is calculated by formula:

Rth ja = Rth jc + Rth ca (1)

Rth jc - thermal resistance junction case,

oC /W.

Application circuit and heat dissipater have to provide TJ ≤ 125

ОС.

Maximum power Ptot,Вт, dissipated by IC for TA , is calculated by formula:

Ptot = (125 - TA) / Rth ja (2)

125 – maximum permitable operating junction temperature,

ОС.
