Hi Team,

Do you have SN74AUC1G07DCKR maximum case temperature data?

Thanks!

Hi Sam ,

Maybe this app note will help in calculating the max case temp :www.ti.com/.../spra953c.pdf

you can also refer to the ti webpage on a wealth of information on thermals and its knowhow here below :
www.ti.com/.../midlevel.tsp

The Tc can be calculated using Tc = Tjmax - (psiJT*power) equation ; Tjmax is 150C whcih is the max junction temp and the power dissipated would be the max power from static and dynamic currents . Please refer to the app note for calculating the power dissipation in the CMOS devices www.ti.com/.../scaa035b.pdf

I have requested for the thermal numbers for the dckr package.

Hi Shreyas

Could you provide θjc for me? The datasheet only has θja.

My customer need this information to calculate the Tc max as well.

Thank you
