DEFINITION

Classification: 327/569

Unijunction transistor:

(under subclass 568) Subject matter including a single junction three electrode solid-state device with two of the electrodes being connected to one region and the remaining electrode being connected to another region wherein a signal applied to the latter electrode causes a breakdown across the transistor junction allowing a current to flow between the other two electrodes.
