Which item can protect SATA port
1.Array type
2.need pass +-8KV contact
3.Eye pattern need pass Gene1~3.
thanks!

Hello Frank,
thank you for your question and welcome to the Forum!
Our recommendation for SATA protection is ESD102-U4-05L. It fulfills your requirements completely:
Another option you have is ESD3V3U4ULC:
Internally both parts are very similar, the main difference is package. ESD102-U4-05L is preferred solution because of superior package. Older TSLP-9-1 (some call it DFN-10) has outer pads placed further away from GND then inner. Newer TSLP-5 has the same distance between GND and signal pads, thus making all bond-wires equally long. For High-Speed applications like SATA it means minimized insertion loss, differential skew, and more safety margin for your whole system. However, if due to PCB tolerance restrictions or other limitations you wish to stick with more common TSLP-9-1, ESD3V3U4ULC will also offer you reliable ESD protection without interfering with normal operation of your device.
As for signal integrity, right now we are working on delivering you standard-compliant eye diagram measurements. In the meantime, our tests show good performance for Gen1-Gen3 SATA, without visible impact on eye diagram.
If you have further questions or need assistance with your application-specific problems, feel free to contact us through this forum or directly.
Best regards,
Anton Gutsul

Our recommendation for SATA protection is ESD102-U4-05L. It fulfills your requirements completely:
- It's a 4-line array in TSLP-5-2 Package
- ±24 kV (air)/ ±20 kV (contact) ESD-robustness according to IEC61000-4-2
- Negligible impact on eye diagrams for Gen1-3
Another option you have is ESD3V3U4ULC:
- It's a 4-line array in TSLP-9-1 Package
- With ±20 kV air/contact ESD-robustness according to IEC61000-4-2
- Negligible impact on eye diagrams for Gen1-3
