SMD diode silk screen, how to confirm the model?

What do the silkscreen letters on the SMD diode mean? How to confirm the model according to the silkscreen symbol on the SMD diode? Pingshang Technology will answer for you!

The SMD diode silk screen identification symbol is composed of: graphics + letters + numbers, etc. The range of diode types is extremely wide, and different diodes sometimes have the same package form. Therefore, it is difficult to determine the model based on the identification symbol alone without the actual picture.

Next, take the diodes supplied by Pingshang Technology as an example, and list some of the more common types of diode silk screen identification symbols:
