Notes:
1 * - Rth ja - thermal resistance “junction-air” (for IC without additional external heat sink), ÎÑ/Wt. The same
parameter in analog IC is Rth ja = 125 ÎÑ/Âò (by “Siemens” information data). Thermal resistance “junction-air” of
this circuit is determined in the course of research & development work.
For the circuit with additional external heat sink:
Rth ja = Rth jc + Rth ca ,
(1)
Where Rth jc – IC thermal resistance “junction-case”, ÎÑ/Wt. . The same parameter in analog IC is Rth jc = 25
ÎÑ/Wt ((by “Siemens” information data). Thermal resistance “case-air” Rth ca in the designed IC is determined
by heat sink structure and specified by IC consumer.
Heat sink, switching “on” mode (power consumed) and ambient temperature should ensure junction
temperature not more than TJ +125 ÎÑ.
2 Absolute maximum power Ptot,Wt, dissipated by the IC at the ambient temperature TA , is determined as:
Ptot = (125 - TA) / Rth ja ,
where 125 – absolute maximum junction operation temperature, ÎÑ
