DS90LV011AH: Need Tj

Part Number: DS90LV011AH


Tool/software:

Hi Support Team,

I need the Tjc (Thermal Impedance Junction to case) & Tc (Maximum Case Temperature) information for DS90LV011ATMFX/NOPB, but I couldn't find it in the datasheet.
Could you please provide this information?

Thank you!

  • Hi Sky,

    This is an older device that originally was made by National Semiconductor originally so they didn't include these parameters typically in the datasheet. 

    I can request our thermal modeling team to perform the analysis to get these specifications - usually this takes up to 2 weeks - but right now there are a lot of requests coming in so they have been a bit slower and there is a US holiday next week - so the analysis may take longer than 2 weeks. 

    I will update you with the information when it is available - I hope to have it within 2 weeks but it could be a bit longer. I will update you at the 2 week point to let you know if I am still waiting on the analysis.  I apologize for the delay and appreciate your patience while we get this information for  you. 

    Best,

  • Thank you for your response.
    I kindly ask you to continue monitoring the relevant parameters of this material.
    Please let me know as soon as there is any update. Thank you.

  • Hi Sky,

    I will keep you updated when I get new info - unfortunately they do seem to be a little behind on the analysis queue at the moment, however, when that changes I will be sure to let you know.

  • I’ve noticed that some time has passed; could you please share the current progress or the anticipated plan with me?

  • Hi Sky,

    I talked with our thermal team last week and I was told that they should have had it at the end of the last week - we still don't have it complete. They are running really far behind - I apologize for the delay but as soon as I know more information I will share because my hands are also tied right now - I am not trying to withhold any information from you and I understand the frustration but right now we have the same amount of information I am afraid. 

    I hope to have information by the end of this week - but they have been really delayed. 

    Best,

  • Hi Sky,

    Please see thermal analysis below - I apologize for the delay on this!

    Result-Theta JB (standard datasheet value) 43.5
    Result- Psi JT (standard datasheet value) 19.3
    Result- Psi JB (standard datasheet value) 43.2
    Result-Theta JC, bottom (standard datasheet value) n/a
