They are not directly interchangeable with conventional UJTs but perform a similar function. ; It is widely used as triggering device for silicon control rectifier (SCR) and TRIAC. PUT – Programmable Unijunction Transistor Characteristics of PUT. The programmable unijunction transistor, or PUT, is a multi-junction device that, with two external resistors, displays similar characteristics to the UJT. Hence, the name "programmable" is used. Triggering Voltage of Unijunction Transistors. คำนิยามในภาษาอังกฤษ: Programmable Unijunction Transistor. A unijunction transistor is a 3 terminal semiconductor device which is unlike a BJT has only a single pn junction. It is basically designed to be used as a single-stage oscillator circuit for generating pulsed signals suitable for digital-circuit applications. This component is especially famous for its negative resistance property and … The triggering voltage of a unijunction transistor is the voltage that is needed on the emitter lead to switch the transistor to the on state so that a larger current flows through the base leads. The Programmable Unijunction Transistor is designed to enable the engineer to program unijunction characteristics such as RBB, ¿, IV, and IP by merely selecting two resistor values. The UJT is the simplest of all the trigger devices. Why the transistor combination is also called a PUT : Programmable Unijunction Transistor?

The programmable unijunction transistor, or PUT, is a close cousin to the thyristor. It has 3 terminals like other transistors and are called: K … Programmable Unijunction Transistors 152. The PUT is similar to the unijunction transistor (UJT), but its intrinsic standoff ratio can be set by two external resistors. A unijunction transistor consists of two bases (B1, B2) attached to a resistive bar of silicon, and an emitter in the center. PUT is not a UJT (junction transistor). It is used as voltage detector. Unijunction Transistor, or simply UJT has an emitter and two bases, unlike a normal transistor. The open circuit maximum amplitude of each of these signals is around 0.56 volt, however this could deviate a bit depending on specific UJTs. The type 2N2646 unijunction transistor works nicely inside this indicated set up. In a unijunction transistor, the base region is divided into two parts by the emitter. Like the thyristor it consists of four P-N layers and has an anode and a cathode connected to the first and the last layer, and a gate connected to one of the inner layers. PUT - Programmable Unijunction Transistor Construction of PUT. You can use All semiconductor datasheet in Alldatasheet, by No Fee and No register. The difference between an ordinary unijunction transistor and a programmable unijunction transistor is the fact that the trip voltage, at which the transistor starts conducting, can be programmed by a reference voltage, that is applied to the gate of the PUT.
