S32G2 Thermals: Customer looking for θ_jc rather than the Ψ_jt

In our S32G2 data sheet we provide:

markdouglas_2-1622148460564.png

and

markdouglas_3-1622148485726.png

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.

  1. Determined in accordance with JEDEC JESD51-2A natural convection environment. Thermal resistance data in this report is solely for a thermal performance comparison of one package to another in a standardized specified environment. It is not meant to predict the performance of a package in an application-specific environment
  1. Thermal test board meets JEDEC specification for this package (JESD51-9).
  2. Junction-to-Case thermal resistance determined using an isothermal cold plate. Case temperature refers to the lid surface temperature.
