Programmable unijunction transistor - Wikipedia
A programmable unijunction transistor (PUT) is a three-lead electronic semiconductor device which is similar in its characteristics to a unijunction transistor (UJT), except that its behavior can be controlled using external components. In a UJT, the base region is …
Programmable UJT, PUT construction, working and theory.
2014年2月5日 · Programmable UJT (PUT). Programmable unijunction transistor or PUT is a close relative of the thyristor family. Its has a four layered construction just like the thyristors and have three terminals named anode(A), cathode(K) and gate(G) again like the thyristors.
Programmable Unijunction Transistor (PUT) Basics - Electrical …
The programmable unijunction transistor is a device that overcomes the major disadvantages of the UJT. This article covers construction, basic operation, and characteristics of Programmable Unijunction Transistor.
Circuit Collection of the Programmable Unijunction Transistor (PUT ...
A specific combination of 2 complementary transistors leads to an interesting self-latching behaviour, that can be compared with the behaviour of a thyristor (aka SCR) or, as the title insinuates, a programmable unijunction transistor, abbreviated to "PUT".
Programmable Unijunction Transistor: - EEEGUIDE
Programmable Unijunction Transistor: PUT Operation – The Programmable Unijunction Transistor (PUT) is actually an SCR-type device used to simulate a UJT. The interbase resistance (R BB ) and the intrinsic standoff ratio (η) can be programmed to any …
potential divider [ but in UJT, it is fixed for the given device] thus it is known as programmable unijunction transistor. The symbol of PUT is shown in figure 12. In this case the gate terminal is c.

Programmable Unijunction Transistor (PUT) – A Quick Rescript
2024年6月22日 · What is a Programmable Unijunction Transistor (PUT)? Simple – it is a three-lead electronic semiconductor device, similar to a unijunction transistor (UJT), except that its behaviour can be controlled using external components ( https://en.wikipedia.org/wiki/Programmable_unijunction_transistor ).
Programmable Unijunction Transistor (PUT) Basic Construction …
2023年1月3日 · A PUT (programmable unijunction transistor) is a 3-terminal 4-layer thyristor acting like a unijunction transistor. An external resistor network “programs” η. The intrinsic standoff ratio is η=R1/(R1+R2) for a PUT; substitute R B1 and R B2 , respectively, for a unijunction transistor.
PUT – Programmable Unijunction Transistor - Electronics Area
Programmable Unijunction Transistor has two states: A cut-off state when the current from A (anode) to K (cathode) is very small. This transistor is polarized in the following way: PUT polarization. When IG = 0,
