S32G2 Thermals: Customer looking for θ_jc rather than the Ψ_jt

[markdouglas]

In our S32G2 data sheet we provide:

and

What they are looking for is θ_jc ( which is the Thermal Resistance Junction-to-Case ) rather than the Ψ_jt ( which is Junction-to-Top (of Package) Characterization Parameter ) that is the second row of Table 6 of your referenced datasheet.

Where can I find the θ_jc ( which is the Thermal Resistance Junction-to-Case )?

Thanks,

Mark D.
