Unijunction Transistor (UJT)

The Unijunction Transistor (UJT) is a three-terminal switching semiconductor device. It contains an n-shaped silicone object bar with a terminal attached to its two ends known as base one and base two. The third terminal is connected to a highly enclosed p-type material attached to the bar section of its length and is known as emitter. As there is only one corrective cross within the device, it is therefore called the 'Unijunction' transistor. The characteristics of the single junction transistor show the wrong resistance if it finds use in resting oscillator circuits for various applications.

A certain npn silicon transistor has vBE=0.7 V for iB=0.1 mA at a temperature of 30°C. Sketch the input characteristic to scale at 30°C. What is the approximate value of vBE for iB = 0.1 mA at 180°C? (Use the rule of thumb that vBE is reduced in magnitude by 2 mV per degree increase in temperature.) Sketch the input characteristic to scale at 180°C.

This is ohmic region 2.. but after a perticular pt. (Pich off voltage)When Vgs Is zero. Id=Idss and is constant (as Vds goes on Increasing Vgd set such width off deplation region to Id become constant) This is active region of JFET 3 but on further Increasing Vds , Id starts suddenly increase (breack down condition) What reason this should happen?
