what is ST e3 G component ?

[OGOR.1]

Hi all,I need some help to know what is the reference of this component ? I can read ST e3 G FBo Z205 but it's impossible to find something like that on the net to purchase it. I need 2 of its. I'm in France if you have a resealer which is seeling this?

Is it a kind of Zener diode ? if yes what ios the correct ref to purchase it?

Best Regards

thank you, how do you know that this is this ref SMCJ24CA ?

[OGOR.1]

regarding my model which one I have to take unidirectional ou bidirectional ? I put others picture of the item.

Cause that's what the datasheet says it is, along with the information that it's the Bidirectional TVS, which can also be observed from the lack of a white bar conferring direction

Might want to look at what actually failed there, diodes seem to have conducted more than the traces

I hope no but I will change the diode and see if the relay behind is ok or not.

This is a card for a swimming pool roller shutter and in manual position I can open and close the shutter, I cross the fingers :anxious_face_with_sweat:

thanks for the big help :ok_hand:
