WebTRIAC can act as AC switch. DIAC can act as AC switch. Ions do not move in a PN junction. PN junction can be made by physically joining P type and N type semiconductor. How many layers and junctions does an SCR have? What is the full form of SCR? ... WebSilicon Controlled Rectifier. We know that the diode allows electric current in one direction and blocks electric current in another direction. In other words, the diode converts the AC current in to DC current.This unique behavior of the diodes makes it possible to build different types of rectifiers such as half wave, full wave and bridge rectifiers.
