Need help to identify component

[Waerloga]

Hi folks, I hope you're able to help me out.

I need to replace a few of the components in the picture. Sorry for the poor quality.

I did of course google the markings but have had no results.

- The measurements of the package is 2.4mm x 4.2mm.

- To me it seems that in the top-left, is the STMicroelectronics logo.

- Next it says "e3" in a circle. Next to that it says "VU" or VO".

- The middle line says "DUK".

- The last line seems to say "GP944".

- The left side if the chip seems to have a line marking polarity.

- I believe the component to be either a diode or a uni-polar capacitor.

Thanks in advance and best regards

-Kenneth
