Questions with Transistors - Programmable Unijunction

  • Ask: What is the main application of unijunction transistor?

    Answer: The most common application of a unijunction transistor is as a triggering device for SCR's and Triacs but other UJT applications include sawtoothed generators, simple oscillators, phase control, and timing circuits. The simplest of all UJT circuits is the Relaxation Oscillator producing non-sinusoidal waveforms.

  • Ask: Why is programmable applied in put?

    Answer: The PUT is similar to the unijunction transistor (UJT), but its intrinsic standoff ratio can be set by two external resistors. Hence, the name "programmable" is used.

  • Ask: What is unipolar junction transistor?

    Answer: A Uni Junction Transistor (UJT) is a device that is formed with a single junction of p-type and the n-type of the semiconductor material. It resembles to that of the diode with a single junction of the P-N. It looks almost like that of the Junction Field Effect Transistor (JFET).

  • Ask: What is peak point and valley point in Ujt?

    Answer: 2 shows the typical family of VE /IE characteristics of a UJT at different voltages between the bases. It is clear that peak-point voltage (=\u03b7VBB+VD) falls steadily with reducing VBB and so does the valley-point voltage Vv.
