UJT Unijunction Transistor Symbol, Construction, Working & Applications

The Unijunction Transistor (UJT) is a three-terminal semiconductor device that is mainly used for triggering, pulse generation, relaxation oscillators, and phase control circuits. Unlike the Bipolar Junction Transistor (BJT) or Field Effect Transistor (FET), the UJT does not function as an amplifier; instead, it acts as a switching device with negative resistance characteristics. The UJT […]
