    Question

    Which statement is TRUE regarding SCR

    Thyristor?
    A Silicon Controlled Rectifier is three terminal, four layered device. Correct Answer Incorrect Answer
    B Silicon Controlled Reconstructor is three terminal, three layered device. Correct Answer Incorrect Answer
    C Silicon Controlled Reconstructor is three layered device. Correct Answer Incorrect Answer
    D Silicon Controlled Rectifier is two terminal, three layered device. Correct Answer Incorrect Answer

    Solution

    A Silicon Controlled Rectifier (SCR) is a semiconductor switching device that belongs to the thyristor family. It is built with four layers of alternating P and N material (PNPN) , which form three junctions. It has three terminals : anode, cathode, and gate. The SCR remains in the OFF state until a gate pulse is applied, after which it conducts current from anode to cathode as long as it is forward biased.
