The objectives and goals of this quiz is to help … WebProgrammable 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 transistor (UJT), but its intrinsic standoff ratio can be set by two external resistors. Hence, the name "programmable" is used.
