LMH6715: junction to board thermal resistance

Hello Art,

I can definitely start the process for getting thermal information for you.  In addition to needing θJB, are there any other thermal data points you would like to know?  Are you looking for values performed under standard datasheet conditions, such as 25C ambient temperature?  

Please provide any details regarding package type, power consumption, or other factors if you would like thermal information from a certain test condition.  Otherwise, I will work on getting a baseline standard junction to board thermal resistance for the LMH6715.  This standard test conditions/power consumption scenario would complement the datasheet information, versus a custom test condition for a very acute need.  If the concern involves knowing the typical θJB, I would suggest proceeding with standard test conditions.  Please respond with any potential changes in timeline or need as we proceed, in addition to confirming the use of typical test conditions for thermal modelling.

Best,

Alec

Thank you for looking into this Alec!

I will get back to the customer for details and inform you as soon as I have the additional information requested.

Art,

I will be on the lookout for an update.  You may also email me the information as well; I am fairly easy to find in the TI directory.

Hello Alec,

The typical values and test conditions for θJB will suffice.

How long do you think this will take?

Thanks!

Hello Art,

The default timeframe to interface with the thermal modelling team is ~2 weeks, is there a specific date you require this information by?  I have already submitted the request earlier this week; I can amend the request to try and accommodate a faster timeline.

Best,

Alec

Hi Alec,

I already notified the customer of the timeframe and will let you know in case he has a target date.

Thanks!

Hi Art,

Thanks for the update!  I've passed along the information the thermal analysis team needs, so we should be all set.

I'll reach out with updates.

Best,

Alec

Thanks Alec!

Art

Art,

You're welcome!

I am glad I was able to help!
