Programmable unijunction transistors (PUT) are three-terminal thyristors that are triggered into conduction when the voltage at the anode exceeds the voltage at the gate. The PUT is similar to the ...
Unijunction transistors (UJTs) are three-terminal devices that have only one PN junction. When an aluminum lead is attached at one side of a bar or block of N-doped silicon, the attachment point ...
