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.

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?

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 MĪ© in both directions, while the one still on the board shows no measurable... -
I have DRUCK UPS-III-IS Loop Calibrator to repair, and I found one faulty diode (O.L. both ways, even out of the circuit). The SMD code on it is E27 NMC. by ON Semi. I can't find anywhere on the internet what kind of diode it is. Being the calibrator, all elements may be crucial, to be exact, so I really don't want to mess up with any diode there. Especially if it needs to be Shottky or a particular Zener. It is connected between a Poly capacitor and in series with another (different) diode (MX47A) - pictures attached.... -
Please help me identify this zener diode.
I find it hard to see the datasheet. The diode was found on 14TB 3.5" WD HDD
I'm looking into having it replaced.
Pictures attached... -
Heyo
I'm trying to perform data rescue on this drive and don't want to make a mistake. I've found a burned diode and a shorted capacitor right next to it. I've found a component on eBay that seems to match up. Can someone confirm please? Also I don't mind replacing it with a compatible component if it's easy to get hold of.
