Ujt Symbol Diagram. Figure 5 ujt relaxation oscillator circuit diagram. The circuit consists of the ujt and an rc timing circuit.
The circuit consists of the ujt and an rc timing circuit. One relatively popular application of the ujt is for triggering power device such as the scr. A unijunction transistor is composed of a bar of n type silicon having a p type connection in the middle.
Figure 5 ujt relaxation oscillator circuit diagram.
The diode symbol shown in the internal circuit model represents the p n junction formed between the heavily doped p region e and the lightly doped n type bar. The schematic diagram symbol for a unijunction transistor represents the emitter lead with an arrow showing the direction of conventional current when the emitter base junction is conducting a current. Symbol and construction of unijunction transistor ujt in unijunction transistor the pn junction is formed by lightly doped n type silicon bar with heavily doped p type material on one side. The diode symbol shown in the internal circuit model represents the p n junction formed between the heavily doped p region e and the lightly doped n type bar.
