Recently we got some samples of STVVGLNAT. Parts label show surface marking "STVVGLNAT L4AA" but parts surface show "L4AA" only. We cannot find the detailed information about the marking from datasheet. We hesitate that the samples are fake and are trying to find some golden samples to compare. However, it seems that all sales do not have this product now. I would like to ask if anyone can explain the marking information or tell me where to get those golden samples? Thank you very much!
