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