6 RD4HMS2 single-stage amplifier with f=135- evaluation board 4. Thermal Design of Heat Sink Tr Pb Junction point of MOSFET chip (in this package) R th(ch-pb bottom) =R th(ch-case) +R th(case-pb bottom) =5. (deg. C./W) Pe Tch (delta) =(Pout/Efficiency-Pout+Pin) x R th(ch-pb bottom) =(4W/5%-4W+.2) x 5. = 21 (deg. C.) Also, operating Tj ( Tj (op) )=12 (deg. C.), in case of RD series that Tch (max) = 15 (deg. C.) Therefore T Pb bottom-air as delta temperature between Pb bottom and the ambient 6 deg. C. T Pb bottom-air = Tj (op) - Tch (delta) - Ta (6deg.C.) = =39 (deg. C.) In terms of long-term reliability, Tj (op) has to be kept less than 12 deg. C. i.e. T Pb bottom-air has to be less than 39 deg. C.. The thermal resistance of the heat sink to border it: Rth (Pb bottom-air) =T Pb bottom-air /(Pout/Efficiency-Pout+Pin)=39/(4W/5%-4W+.2)= 9.3 (deg. C./W) Therefore it is preferable that the thermal resistance of the heat sink is much smaller than 9.3 deg. C./W. 6/23
