Product Description

UJT (Double base diode) consists of a bar of lightly doped n-type silicon with a small piece of heavily doped P type material joined to one side. It has got three terminals. They are Emitter(E), Base1(B1),Base2(B2).Since the silicon bar is lightly doped, it has a high resistance & can be represented as two resistors, rB1 & rB2. When VB1B2 = 0, a small increase in VE forward biases the emitter junction.

Scope of Learning:

 To study UJT triggering of thyristor.
