Correct Answer : Option (D) : Bisecting the SCRs top two and bottom two layers
Explanation : The two- transistor model of the SCR is obtained by bisecting the SCRs top two and bottom two layers. The two-transistor analogy of SCR refers to a method of producing an SCR as a combination of an np-n and a p-np transistor. SCR is a three-terminal device having a p-n-p-n structure. The three terminals of the junctions are the cathode, anode and gate terminal.
