Discuss the two transistor model of an scr
WebJan 10, 2024 · 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 acts as a control … WebTwo Transistor Model of an SCR. An SCR can be shown as two back-to-back connected bipolar junction transistors as shown above in the picture. Both the transistors are PNP and NPN type respectively. Here T 1 denotes the PNP type while the NPN type transistor has been denoted by T 2. The base terminal of the T 1 transistor is connected to the ...

WebJan 14, 2024 · An SCR is constructed with the four layers that consist of the P-type and the N-type semiconductor material. These are layered in such a way that it tends to form three junctions that are J1, J2, and J3. The three terminals that are attached to it are known as anode, cathode, and gate. WebThus the equivalent circuit of the SCR can be treated as constituted of two transistors, a P-N-P transistor and an N-P-N transistor connected as shown in Fig. 10.5. It is seen from the figure that the collector of each transistor is coupled to the base of the other and thus making a positive feedback loop.
