I moved your topic to an appropriate forum category @AmirAbangah.

In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Thanks for your advice. But the TVS diode is after this component and I think the user markd833 answer`s is correct.

I have no idea! My knowledge of discrete components in surge protection is essentially zero...

Since this component is located at the beginning of the DC power input to the board and before the TVS diode, your answer is very close to reality in my opinion. Thank you very much.

I found a page that explains the difference.
