Hello, did someone know what is this diode? Thanks.
The photo is not clear.
Take a photo of the diode from the correct angle.
The markings look MV or NV. Can you take a straight on picture, or verify what the top markings are?
Is the body of the diode 2.9mm x 1.9mm?
There are a number of SOD-123 package TVS Zener Diodes out there that use NV as a part marking.
Part Number TV02W850B-G-ND is one example
Unfortunately with how many diodes use the NV marking it would be difficult to positively ID.
