Other Parts Discussed in Thread: TPD4E6B06, TPD1S514

HI team 

My customer is using TPD4E6B06 for USB 2.0 protection 

As shown in the data sheet only Data + and Data - is protected using this TVS device

Any input on how to protect the Vbus  line of the usb  from ESD 

Thank you

    Shreenidhi-

    We have the TPD1S514 that is specifically designed to protect the USB Vbus line, offering ESD, overvoltage, and surge protection for the Vbus line. This will be the best way to protect your customers Vbus line.

    The other option if you are interested in just ESD on the Vbus line and not overvoltage is to use a high voltage discrete TVS. If your Vbus is limited to 5V a device like the TPD1E01B09 will work.

    My recommendation for the most robust system would be to use the TPD1S514. Let me know if you have any follow up questions, I'm happy to help your customer find the best solution for there design.

    Thanks,

    Alec
