Example sentencesExamples The unijunction transistor, or UJT, is a three-terminal device with a single pn-junction. This is a good, reliable sawtooth generator and is probably the main use for unijunctions. I was designing circuits in 1967, and it would not have been hard to do just as good a control with the technology of the day (I like programmable unijunctions). All in all, SCR's and unijunctions are probably the simplest and cheapest solutions, and appear to have no disadvantages. Shown on the left is an example of low cost planar unijunctions developed in the 1960s.
