An Scr Has Pn Junctions
The layers are either NPNP or PNPN. A PIN diode is a diode with a wide undoped intrinsic semiconductor region between a p-type semiconductor and an n-type semiconductor region. Unijunction Transistor And Ujt Relaxation Oscillator It has three terminals Gate G CollectorC and Emitter E. . SCR has four layers of extrinsic semiconductor materials.

The outer layers are heavily dopped and the inner. The concentration of impurity in the normal PN-junction diode is about 1 part in 10 8. Like a diode a thyristor is a unidirectional device as well but unlike diode it can be used as an open circuit switch. A portmanteau of memory resistor is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkageIt was described and named in...
