So I built a new project using two IRF3711 MOSFETs (data sheet attached)...My question is I'm not uber proficient at reading data sheets and want to know if, and in particular how you attach a heat sink to a T0-251AA package. They will dissipate between 5.5 and 8 watts depending on voltage.

Can someone explain the calculations required to figure out what the temperature would be? (12vdc to 13.8vdc x 25ohms)

Thanks!
