WebbA silicon controlled rectifier (SCR) is a four-layer solid state current controlling device with 3 terminals. They have anode and cathode terminals like a conventional diode and a third control terminal, referred to as the Gate. SCRs are unidirectional devices, i.e. they conduct current only in one direction like a diode or rectifier. http://subtiwiki.uni-goettingen.de/wiki/index.php/Scr

Webbγ-Alumina with incorporated metal oxide species (including Fe, Cu, Zn, Bi, and Ga) was synthesized by liquid-assisted grinding—mechanochemical synthesis, applying boehmite as the alumina precursor and suitable metal salts. Various contents of metal elements (5 wt.%, 10 wt.%, and 20 wt.%) were used to tune the composition of the … The SCR is a four-layered semiconductor device that forms NPNP or PNPN structure, which eventually forms three junctions J1, J2, and J3. Among the three terminals of the SCR, the Anode is a positive electrode, it will be on the P-layer and Cathode is a negative electrode, it will be on the N-layer of the SCR, the Gate … Visa mer The Symbol of the SCR will be similar to that of the diode, additionally; it has a gate terminal as shown below. The SCR is a unidirectional device … Visa mer To understand the SCR working principlewe have to look into the different ways it can operate.
