could someone help me to indentifY this chip, as i know pine1 output “maybe”, pine2 gnd, pine3 input (24v) it’s on motherboard brand THYSEN ref: UBA2-CMC4+
Hello sar001us,
Welcome to the DigiKey TechForum.
I’m sorry but I was not able to ID that chip. Looks like a voltage regulator at first glance or a transistor but there are no results for anything with that marking of 8B252. SOT89 package looks to be right but there are more than a few options of different ICs within that package.
Sorry for the inconvenience. Perhaps some other tech, or contributor might recognize this SMD IC it with that marking.

Hi sar001us ,
If it offers any assistance, this is a surface mount TO-243AA package, sometimes known as SOT-89-3, 3-HSIP, PW-MINI, and SC-62. Easily identified by having 3 “flat leads” and a tab. The tab allows heat dissipation to the board.
Clicking above link will provide all the component types within that package DigiKey carries, unfortunately there is no way to search based on part markings other than manually searching within each datasheet. Performing an analysis of the circuit and parts around the component may steer you in the right direction of what kind of component this would be.
