2nd row E ?
3rd GP933
Hello feifortheart,
Welcome to the DigiKey TechForum.
It looks to be some kind of diode within the DO-214AC SMA package style. There are a lot in that SMAJ variety that Adam7 showed in that table though I’m not sure how close any of the options are to the one you have since I wasn’t able to find any specs based on the info you provided. The ST is a STMicroelectronics logo and we have a lot of diodes from them in that package case. Unfortunately I could not narrow it down any further.
Thanks @Adam7 @Irfan_Koric your support, I think my device is old(its product around 2000~2005), so the ST code is difference today.
Perhaps this is the diode we are looking for? 
SM6T33A DO-214AA ,SMB VS
Hello,
Looks like Adam7 may have found the part. It has an E T marking even the T is hard to see in the crack. That marking corresponds to ST part SM6T33A which is DigiKey part 497-6493-1-ND
