Could you please provide me with junction to board and junction to case thermal resistance values for this component?

Hello John,

I can work on getting those values for you; in order to begin, could you tell me the package-type you are interested in using in your design?

For the LMH6654, these are:

SOIC (D)

SOT-23 (DBV)

Thank you.

Best,

Alec

Hi Alec,

John included this request in CSC but no information found from our database. He is requesting the thermal information for SOT-23 (DBV).

LMH6654MF/NOPB

Hello Archie,

Fantastic, thank you for sharing! I will get right to work on this; once I have an expected timeline, I will update you. The general basic timeline for these requests is two weeks.

Best,

Alec

Hello John, Archie,

The thermal modelling request has been submitted and I will update you accordingly.

If you have additional questions on the LMH6654, you may ask in the interim.

Best,

Alec

Hello John, Archie,

For the LMH6654MF/NOPB the thermal characteristics are as follows:

Result- Theta JA-High K (standard datasheet value)	169.9 °C/W
Result-Theta JC, top (standard datasheet value)	74.7 °C/W
Result-Theta JB (standard datasheet value)	38.5 °C/W
Result- Psi JT (standard datasheet value)	10.7 °C/W
Result- Psi JB (standard datasheet value)	38.2 °C/W
Result-Theta JC, bottom (standard datasheet value)	n/a

These values only apply to the OPN above (LMH6654MF/NOPB) in SOT-23 (DBV) package.

Best,

Alec
