What does Y stand for in the name of the diode BY 127?

Answer 1

In the word BY 127, the second term is used to indicate the functionality of the diode. In this case, Y indicates rectifier.

A rectifier diode allows the flow of electric current only in single direction. It is used primarily for power supply operation in converting alternating current to direct current. The diode supports higher current flow than a normal diode.
