TPD1E10B06: Is this part correct for MCU GPIO ESD protection?

Matthew Pole

Part Number: TPD1E10B06
Other Parts Discussed in Thread: TSD05C, , TPD1E05U06-Q1, ESD1LIN24,

Hi, I am looking for ESD protection for my 5v MCU inputs and outputs. Is this the ideal component for this application? Just put this next to the connector with maybe a RC circuit after? Thanks!

    Hi Matthew,

    TPD1E10B06 is a very popular option for GPIO ESD protection and would be a valid choice! I'm not quite sure what the other specs for your application are, but after reviewing some of our available parts I found TSD05C has equivalent or better specs, please see the attached comparison file. The packages are different for these devices, meaning that the TSD05C might not be an appropriate option for your application. TPD1E10B06 might make more sense to use because of the smaller package availability, but if the slight increase in specs is more desirable, you might consider some other devices. You can always create your own comparisons by using our ESD & Surge Protection IC Product Selection, which can be found here: ESD & surge protection ICs product selection | TI.com . You can filter by different specifications, change which columns appear, and pull the data into an excel file!

    I hope this helps, please let me know if you have any additional questions!

    Have a great day,

    Joshua Prushing

    Hi Joshua,

    Thanks for the response! The layout is not complete yet so I can implement any footprint currently. The only issue is that I can’t see anywhere to source TSD05C from? 

    also, is there any information on ideal circuitry to go with this divide like resistor and cap values for an rc circuit to go with it? Or is this device good enough on its own?

    I will have a look at you links, thanks! I also need a similar product to clamp to 30v before entering my voltage divider circuits

    Thank you!

    Hi Matthew,

    If by sourcing TSD05C you mean a location to purchase the device, please visit the following link: TSD05C data sheet, product information and support | TI.com

    There is no need for an RC circuit to pair with the device, however some system designers might want to add delay or a filter for downstream circuitry. That is determined based on the application. In terms of device functionality, there is no additional circuitry needed.

    In terms of your last note, I have attached a table below to present some options I found for your 30V clamping needs:

    Vrwm Bi-/uni-directional Number of Channels Clamping Voltage (V) Capacitance (pF) IEC 61000-4-5 rating (A) IEC 61000-4-2 rating (V)
    TPD1E05U06-Q1 5.5 Uni 1 23 0.4 2.5 12000
    ESD1LIN24 24 Bi 1 31 3 3.5 30000

    I selected the TPD1E05U06-Q1 based on your selection of 5.5 Vrwm parts, and I selected ESD1LIN24 because it better satisfies your request of clamping voltage. As mentioned above, the Product Selection Tool will be a helpful resource when finding a part that best fits your requirements.

    If there are any further questions, please do not hesitate to reach out!

    Best Regards,

    Hi Joshua,

    The link just takes me to the page that says that there is no stock avaliable. I also can't find any source anywhere for that component.

    Thank you for the suggestions. Maybe you could help me to see if I have missed something obvious. I have looked at the product selector but it appears you dont have something automotive grade to protect a max 32V line, so Vmrs just over 32V and clamping not far off. Am I missing a component?

    Thanks!

    Hi Matthew,

    This part is set to fully release soon. I see that we have some TIers that are assigned to work with your company, I have reached out to them to work on getting you some samples. I apologize for any confusion!

    In regards to your second point, our auto-qualified parts only go up to 24V working voltage.

    As always, if you have any additional questions, please do not hesitate to ask here!

    Have a good day,
    Joshua Prushing

    Hi Matthew,

    Great news, TSD05C is now available! This link should still work:  TSD05C data sheet, product information and support | TI.com

    I have not heard whether you were able to obtain samples or not, so I wanted to provide the link for you.

    Please let me know if you have any troubles ordering samples!

    Have a great day,

    Josh Prushing

    Hi Josh,

    I have no had the chance to order any yet. I have just seen that the TSD05CDYFR is now avaliable. What is the difference between this and the pre-production PTSD05CDYFR part on the main product page.

    Thanks!

    Hi Matthew,

    The 'P' designates a part that is in the 'APL' phase. This will most likely be removed shortly, as the commercial device is available now (under TSD05CDYFR). I would highly recommend ordering from the TSD05CDYFR device rather than the PTSD05CDYFR.

    Thanks for your quick reply!

    Best Regards,

    Hi Josh,

    I have just noticed that these do not seem to be automotive grade? Is that correct? If so, I won't be able to use them in my future application unfortunately! My previous PCB that this question was about did not need it, this is now done.

    Do you have any suggestions for your best automotive grade alternative?

    Many thanks!

    Hi Matthew,

    Glad to hear your other design is completed! I would recommend TPD1E10B06-Q1 if you need an auto-qualified device. Please see the table below:

      TSD05C TPD1E10B06
    Vrwm (V) 5.5 5.5
    Package Type SOT SOT-5X3 (or W1SON)
    Package Size (L x W) (mm) 2.65x1.3 1.6x0.8 (or 1.0x0.6)
    Bi-/uni-directional Bi-directional Bi-directional
    Number of Channels 1 1
    Clamping Voltage (V) 9.3 10
    IO Capacitance (typ) (pF) 6 12
    IEC 61000-4-5 (A) 30 6
    IEC 61000-4-2 Contact (kV) 30 30
    Max Leakage Current (nA) 50 100

    Unfortunately, these devices are not p2p, but TPD1E10B06 offers the closest specifications out of our auto-qualified devices.

    Please let me know if you have any additional questions!

    Beat Regards,

    Josh Prushing
