WebIt increases with the increase in inter-base voltage V BB. Special Features of UJT. The special features of a UJT are : A stable triggering voltage (V P )— a fixed fraction of applied inter base voltage V BB. A very low value of triggering current. A high pulse current capability. A negative resistance characteristic. Low cost. WebThe UJT Stand for Uni Junction Transistor. It has one PN junction and three terminals. As shown in the below figure. Construction of UJT The UJT is consist of a light doped N-Type of silicon bar, there is a heavily doped P-Type of region at one side of the N-Type of bar.
