Ujt Diagram. The emitter is strongly doped with p impurities and the n region weakly doped with n impurities. Two bases and one emitter.
Two bases and one emitter. Figure 2 ujt internal voltage drops diagram the relative values of the voltage drops in the ujt are dependent on the relative values of the internal resistances. The ratio of rb1 to the total interbase resistance rb1 rb2 will fix the value of the voltage at the cathode terminal of the emitter base junction.
In the a image the physical structure of this device is shown.
Figure 2 ujt internal voltage drops diagram the relative values of the voltage drops in the ujt are dependent on the relative values of the internal resistances. The ratio of rb1 to the total interbase resistance rb1 rb2 will fix the value of the voltage at the cathode terminal of the emitter base junction. One relatively popular application of the ujt is for triggering power device such as the scr. Unijunction transistor ujt the ujt or unijunction transistor is constituted by two polluted regions with three external terminals.
