Gate turn-Off thyristor (GTO)

A gate turn-off thyristor (GTO) is three terminal semiconductor device – made up of four layers of alternating P-type and N-type material. Just like a conventional thyristor, it is also a current controlled, minority carrier device. The gate turn-off thyristor was invented with the purpose to address the difficulties in the turn OFF mechanism of … Read more

MOSFET – Structure, working principle, symbol and applications

A Metal Oxide Semiconductor Field effect transistors, commonly known as MOSFET, are semiconductor switching devices that have three terminals which are the gate, drain and source. They are unipolar transistors, this means they depend on one type of charge carriers which can either be holes or electrons. They are much simpler to fabricate compared to … Read more

BJT – Bipolar Junction Transistors

A Bipolar junction transistor, commonly known as BJT, is a Si or Ge semiconductor device that is structured like two p-n junction diodes connected back to back. It has two outer regions which are the emitter and collector and another region in the middle known as the base. The bipolar junction transistor is called bipolar … Read more
