THVD2450V: Pressure Limit

Matt DeBenedictis

Part Number: THVD2450V

Tool/software:

What is the pressure limit for this part? I am looking to top cool this part with a thermal interface material to a cold plate.

Thanks!

    Matt,

    I'm not sure if we have this information specifically, but we can check with some internal teams to see what's available. Can you share the expected weight/pressure from the cold plate?

    Regards,

    Hi Eric,

    I would be applying around 25-30psi of pressure to this component. 

    Thanks!

    Hi Matt,

    I have reached out to our internal packaging team to see if this would be okay - I am hoping to get an answer within 24 hours but it may not be until the end of the week. 

    I will keep you updated.

    Hi Matt,

    So I got some information back from our packaging team - we don't characterize this data for this device (and it sounded like we don't do it for any of our packages). They said they may have a relevant case study - but I don't know what that entails. When I receive that information I will let you know, but we don't give any specific pressure limit on this device.

    Hi Matt,

    Sorry for so many back to back replies - while we don't characterize the parameter directly my packaging team gave  a general guidance of no more than 20N. 

    20N / 9mm^2 (area of package)--> ~322psi. So while the reference material is on a QFN and not a DRC - they are the most similar to each other. Since the general guidance limit is well above the 25 to 30 psi you want - I think there isn't a lot of risk to go ahead and use because that should be a relatively safe level. I do want to stress that we don't characterize or specify a specific limit on this device, but from our best information available the risk should be pretty low at those pressures.
