Question

What are the terminals of a unijunction transistor?

(a) Collector, Base and Emitter

(b) Emitter, Base 1 and Base 2

(c) Gate, Drain and Source

(d) Gate, Drain, Body and Source

The question was asked in semester exam.

I would like to ask this question from The Unijunction Transistors topic in division Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

The correct option is (b) Emitter, Base 1 and Base 2

Best explanation: The unijunction transistor consists of a single solid piece of N-type channel with its two outer connections marked as Base 2 and Base 1. The third connection is the Emitter and it is located along the channel. The emitter lies closer to base 2 as compared to base 1.
