A Unijunction Transistor (UJT) is a three-terminal semiconductor device that consists of a single P-N junction formed between a thin P-type base region and an N-type emitter region. The other terminal is connected to the N-type base region.
The other options are:
- BJT (Bipolar Junction Transistor): It consists of two P-N junctions forming three terminals: emitter, base, and collector.
- FET (Field-Effect Transistor): It consists of a gate, a source, and a drain, but its internal structure varies depending on the type (JFET, MOSFET).
