APL1085 transistor What does the bottom row code mean?

[onedumbquestion]

Mine says APL1085 and below it says QM28T I need to replace it but I can't find an exact match although I see a lot of APL1085 transistors for sale, just with a different code below APL1085 like
APL1085UC-TRG TO252 APL1085 TO-252 APL1085UC

Have you looked at the data sheet? You are probably looking at the date code.

Oh, and this isn't a transistor, it is an integrated voltage regulator.

Wow Cool Thanks I'm new to e-repair I watched a video said they were mosfets and to put my DMM on beep and expect one beep for the good one's and two for the bad What happened in my case was all of them set off a series of beeps, more than 2, except this one, although it creates a numeric reading My DMM isn't the same one he was using I have a WeePro Vpro850L
