Question

Unijunction transistors have unidirectional conductivity and positive impedance characteristics.

(a) True

(b) False

I have been asked this question in homework.

My enquiry is from The Unijunction Transistors topic in section Field-Effect Transistors of Electronic Devices & Circuits

Answer 1

Correct answer is (b) False

Explanation: Unijunction transistors have unidirectional conductivity and negative impedance characteristics. During circuit breakdown, they function more as a variable voltage divider. They are used in gate pulse, timing circuits and trigger generation.
