Hi All
Repairing an Industrial PC Powersupply.
This Component has gone short circuit. It is in Parallel with several electrolytic caps, so I presume it is a cap.
I have not tried to power it up without this, as I don't want it to cause any more damage if it is essential.
I have searched on ST, and on google, but cannot find it.

Any suggestions / what it is?

Looks like SM15T36CA : https://www.st.com/resource/en/datasheet/sm15t36ca.pdf

Thank you.
That looks like what it is. It is starting up without the ESD Protection.
I will order a replacement shortly.

Hi all
I have several of these IC, but haven't been able to find any data about it, not even the manufacturer.
Any advice ?
