Vw = Permanent working or operating DC voltage.
HOI SPOI CALCULAIION
©hot spot = ©ambient + (Pd + Pt) x (Rth + 7.4) ©hot spot = ©case + (Pd + Pt) X Rth
with Pd (Dielectric losses) = Q x tg80
== [/2 X Cn X (Vpeak to peak)2 X f ] X (2 X 10"4)
Pt (Thermal losses) = Rs x (Irms)2
where Cn in Farad Irms in Ampere f in Hertz V in Volt Rs in Ohm © in °C Rth in °C/W Rth : Rth case/hot spot in °C/W
