HOT SPOT CALCULATION
θ_{hot spot} = θ_ambient + (P_d + P_t) x (R_th + 7.4)
θ_{hot spot} = θ_case + (P_d + P_t) x R_th
with P_d (Dielectric losses) = Q x tgδ₀
⇒ [ ¹â„2 x C_n x (V_{peak to peak})² x f ] x tgδ₀
(see tgδ₀ curves page 3)
P_t (Thermal losses) = R_s x (I_rms)²
where
C_n in Farad
V in Volt
R_th in °C/W
I_rms in Ampere f in Hertz
R_s in Ohm
θ in °C
R_th : R_th case/hot spot in °C/W
