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

As of 2012 ON Semiconductor manufactured a part: 2N6027. 2N6028 was also made in the past. [1]
