this little baby is marked R54 BH ... is it a npn BJT? A MOS? A LDO?
I can't find anything online and also in the smd code databook ....

Hello,
Device: PocketBook InkPad 3
Mainboard: XRZ_E091_PB740-VTTOA-V1.1 / 2017-10-12
I'm replacing the broken microUSB connector on this e-reader, and during inspection after desoldering, I noticed a loose black SMD component marked "CT". One of them was torn off along with the pad, while the other one (marked in the photo) is still in place.
I would appreciate help identifying this component.
Measuring the loose component with a multimeter gives 5.84 MΩ in both directions, while the one still on the board shows no measurable... -
I am not sure if this is the right place to post this but I need help identifying a surface mount rectangle diode and all that is printed on it is "DK" it seems to be open so I can't read anything off it. It's in a HP laptop by the power switch. TIA for any help.

Could somenone help me find a compatible or equivalent one?

Thank you in advance.... -
Hey guys! my name is kyle, new to motherboard troubleshooting and a little confused still on chip identification if yall could help identify this chip..

Hi:
I have what it might seem a zener diode. It's marked as E57, but I haven't found any reference that might match my observations.
I've took one from the same circuit and tested isolated with the power supply and a 1k resistor. with 10V, the possible zener stays at 6.6V.
It seems a SOD123 package. It measures (2.6mm x 1.6 mm).
Any idea? it's a 6.6V zener?
