A three-terminal, semiconductor device with a negative resistance characteristic that is used in switching circuits, oscillators, and wave-shaping circuits.
It is device with three terminals acting as a diode with its own internal voltage divider biasing circuit.
A trigger device that has an emitter lead (e) and two bases B1 and B2.
A type of transistor consisting of an emitter and two bases. A three-terminal device whose trigger voltage is proportional to its applied biasing voltage.
A Unijunction transistor (UJT) is an electronic semiconductor device.
