Graph of PUT characteristic curve, similar to UJT
Programmable unijunction transistor (PUT) is a three-lead electronic semiconductor device with which is similar in characteristic to unijunction transistor except that it is programmable.[2]
Construction
In construction, Programmable unijunction transistor is similar to Silicon controlled rectifier. It consists of four layers, two p-type layers and two n-type layers in equal proportion.[1]
Applications
- It is used to trigger Thyristors.
- It is also used as Relaxation oscillator.
As of 2012 ON Semiconductor manufactured a part: 2N6027. 2N6028 was also made in the past.[1]
