"the marking is SUA, which corresponds to the SMA6F5.0A-TR, which can be found today with 6AI marking."

Thanks for reply ,

What about the first TVs Diode which stands with SUG marking ?

"SUG stands for the SMA6F13A-TR"

@Lina_DABASINSKAITE , here's another example of missing labels. The forum sees a slow but steady stream of such chip identification help requests, but there's no forum label for it. In lieu of a dedicated subforum, a dedicated label would be nice.

@BarryWhit There is a label: Power Managment > Discretes

Well, maybe not the ideal combination, but should mostly work - doesn’t it?

As it is it shows up in my feed, I'm Ok with it, and the more times we answer the better the chance of a direct Google Hit for the self-service customers

These particular diodes being a pain due to lack of marking documentation, and the markings changing from current issue parts.

Yes, this may be a little confusing, but all SMA6F (package SMA Flat) are obsolete and no longer visible on the ST website, please do not confuse it with SMA6J (package SMA).
