Application of UJT

UJT stand for unijunction transistor, it is most commonly used in high switching speed, Here this article gives the information about the application of UJT to better understand this topic.

Application of UJT:


  • The most application of the UJT  transistor is as a triggering device for SCR and TRIACS.
  • UJT applications include simple oscillators, phase control.
  • The simplest of all UJT circuits is the relaxation oscillator and it producing non-sinusoidal waveforms.
  • It is used as a voltage detector.
  • UJT is mainly used in phase control and timing circuits.
  • It is used in saw tooth generators.
  • It is used in oscillator circuit design.
  • UJT can also be used as to measure the magnetic flux.
