TPSM5D1806: TPSM5D1806 thermal resistance details

swadish MS

Part Number: TPSM5D1806

For TPSM5D1806, in the datasheet, only thermal characterization parameters are mentioned and thermal resistance values. Can we get details of the same?

This is the characterization parameter, we are looking for thermal resistance values.

The RthetaJA is 13.9 C/W. .

We would require the Junction to case(top) resistance parameter.

Here is the ThetaJC that was modeled

Thank you, is there also a Junction to case bottom, since this is a QFn package.

Since the information is not readily available, the junction to case bottom will need to be simulated. I made the request and will post when the data is available

Here is the result for the RThetaJC bottom.
