SN55189A: ESD and other questions regarding part SNJ55189AW

Part Number: SN55189A
Other Parts Discussed in Thread: ALP

Tool/software:

  1. ESD sensitivity? 

From the website, - ESD sensitivity is shown as 0 kV. Is this still the case if the unit changes to V instead of kV? We need a classification (0A, 0B, 1A, 1B etc.)

  1. Please provide cage code for the manufacturing/assembly location (Thailand) 
  2. We want it to confirm whether all 3 parts are hermetically sealed
  3. Is there a soldering profile other than maximum condition for soldering (e.g. 300C for 60sec)
  4. Is there a plan to discontinue the part? 
  5. What does J represent in SN"J"55189AW? Is this related to QPL listing?  

Thank you so much for your support! 

  • Hi Jenny,

    A lot of these question I'll need to ask around to find them. This may take a bit of time. (maybe a week or more depending if I can't find the correct contact). 

    From the website, - ESD sensitivity is shown as 0 kV. Is this still the case if the unit changes to V instead of kV? We need a classification (0A, 0B, 1A, 1B etc.)

    I don't think we have done an ESD test for this device. The datasheet doesn't specifically call out any type of testing at all. I also couldn't locate any ESD tests done for this device in our databases, the Sn75 version wasn't tested either. To ensure ESD ratings you will likely need to use external ESD.

    Please provide cage code for the manufacturing/assembly location (Thailand) 

    I'll need to double check on this. Do you mean for the SNJ55189AW (CFP package)? I found two separate sites for A/T, ALP and MTT

    We want it to confirm whether all 3 parts are hermetically sealed

    I'll need to double check on this. For this one, I think I may know who to contact so this may be quicker to get an answer.

    Is there a soldering profile other than maximum condition for soldering (e.g. 300C for 60sec)

    The same contact I need to reach out to for the previous question might be able to answer this one as well... 

    Is there a plan to discontinue the part? 

    I don't think I can specifically tell you if a part is going to be discontinued before any official announcement has been made. I can tell you the device is in an older process technology (150mm wafer) where TI is trying to move to newer process technologies that use 300mm wafers. 

    What does J represent in SN"J"55189AW? Is this related to QPL listing?

    In the document Linked above, I found the following on page 8:

    "SNJ = MIL-PRF-38535 (QML)
    SN = Commercial Processing"

    Sorry I don't have an exact date for when I can get the information you need. Please check back in with me on Wednesday.

  • Thanks for taking a quick look, Bobby! Yes. It is for SNJ55189AW. We would like to have ESD answer as soon as possible. We really look forward to hearing back from you. 

  • Jenny,

    For soldering profiles, please refer to these two documents: https://www.ti.com/lit/an/slvaeu0/slvaeu0.pdf and https://www.ti.com/lit/an/snoa292j/snoa292j.pdf
