Hi E2E,

Good day.

What is the operating Junction temperature (Tj) and case temperature (Tc) of TUSB3410 in VF (LQFP) package?

Is the Tj the same as the Tstg? and the Tc is 70C?

Regards,
Carlo

In the original post I've noticed that the θJa was used instead of the θJc for Tj computation, please confirm.

Hi Carlo,

I would refer to the document linked below as it will provide some useful information on calculating Tj. ψ_JBis what you should use for calculating TJ for a given device.
