Image unijunction transistors.jpg thumb right Unijunction transistors Image UJT symbol.svg thumb 200px right Circuit symbol A unijunction transistor UJT is an Electronics electronic semiconductor device that has only one p n junction junction . The UJT has three terminals an emitter E and two bases B1 and B2 . The base is formed by lightly doped N type semiconductor n type bar of silicon. Two ohmic contacts B1 and B2 are attached at its ends. The emitter is of P type semiconductor p type and it is heavily doped. The resistance between B1 and B2, when the emitter is open circuit is called interbase resistance. There are three types of unijunction transistors The original unijunction transistor, or UJT, is a simple device that is essentially a bar of N type semiconductor material into which P type material has been diffused somewhere along its length, defining the device parameter math eta math . The 2N2646 is the most commonly used version of the UJT. The complementary unijunction transistor, or CUJT, that is a bar of P type semiconductor material into which N type material has been diffused somewhere along its length, defining the device parameter math eta math . The 2N6114 is one version of the CUJT. The programmable unijunction transistor , or PUT, is a close cousin to the thyristor . Like the thyristor it consists of four P N layers and has an anode and a cathode connected to the first and the last layer, and a gate connected to one of the inner layers. They are not directly interchangeable with conventional UJTs but perform a similar function. In a proper circuit configuration with two programming resistors for setting the parameter math eta math , they behave like a conventional UJT. The 2N6027 is an example of such a device. The UJT is biased with a positive voltage between the two bases. This causes a potential drop along the length of the device. When the emitter voltage is driven approximately one diode voltage above the voltage at the point where the P dif ... more details
