A unijunction transistor (UJT) is a three-lead electronic semiconductor device with only one junction that acts exclusively as an electrically controlled switch. The UJT is not used as a linear amplifier. It is used in free-running oscillators, synchronized or triggered oscillators, and pulse generation circuits at low to … See more There are three types of unijunction transistor: 1. The original unijunction transistor, or UJT, is a simple device that is essentially a bar of n-type semiconductor material into which p-type … See more Unijunction transistor circuits were popular in hobbyist electronics circuits in the 1960s and 1970s because they allowed simple See more The device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative … See more The UJT has three terminals: an emitter (E) and two bases (B1 and B2) and so is sometimes known a "double-base diode". The base is formed by a lightly doped n-type bar … See more The unijunction transistor was invented as a byproduct of research on germanium tetrode transistors at General Electric. It was patented in … See more Web29 Sep 2024 · This problem may be overcome by using either a UJT or a PUT trigger circuit. With both circuits, the trigger angle may be controlled from almost 0° to 180°. A representative UJT circuit is shown in Figure 3. Figure 3. Triac load control—UJT triggering. Important points that should be noted for the UJT trigger circuit are:
