Need help identifiying SMD component
« on: June 23, 2021, 08:58:34 am »
Hi!
I need help with identifiying SMD component.
I have two same PCB’s and nave two different component marking for same componenet.
I have device marked similary with RABR, on both PBC’s and they are Texas Instrument LMV393 Dual Comparators in DDU package.
I attached picrures from both PCB’s and SMD Devices (presumable Texas Instrument!)  marked in one with BRBAA and in other one with BRGAA.
This component is on 3.3 Volt rail and it looks like for High current draw, because 6 PIN contact to one point heat dissipation pad on PCB.
Sadly, I could not find any information after week of research.
Maybe somenoe has an Idea what they are?
THANKS in advance!
Regards to all.

Hi again!
After long search: last two pictures above, show VISHAY Si5475DDC MOSFET in 1206-8 ChipFET package.
Datasheet is Attached.

What a weird package.
You'd think they'd mimic the usual SO-8 pinout, or at least put more than one pin for source connection. But then again that might not be necessary for the target ID.

It is weird indeed, but hey, this all contributes to our knowledge and ongoing knowledge of electronics , doesn't it ?

Sometimes i sit and wonder... Beginners coming into the industry need to have a knowledge of parts that goes back to the  60s,
Now i've been into electronics since the 70s and naming conventions have changed a lot for some things and not so much for others

but you're right, one would think they would just go with the SO-8 convention
QUESTION EVERYTHING!!!
