A Unijunction Transistor is a transistor that acts solely as a switch.
put (programmable unijunction transistor) he Programmable Unijunction Transistor behaves much like a unijunction transist or (UJT), but is "programmable" via external resistors (that is, you can use two resistors to set a PUT's peak voltage). Note that the name is a bit of a misnomer -- as a thyristor, it is a four layer device, unlike a true unijuncti on transistor which has but two layers. Like other thyristors, a PUT looks much like a junction transistor with a fourth layer and therefore a total of three P- N junctions. Meanwhile, a third terminal, the gate (G), makes a PUT function like a hybrid of transistor and diode: PUT symbolPUT cross-section PUTs are not often used in BEAM; they're essentially special-purpose devices in electronics, used for lightingcontrol, motor speed control and othervariable power applications. In combination with an SCR they can, though, makea mean solar engine. In a pinch, you can build up something much like a PUT from discrete transist ors wired as a complementaryfeedback Here, as soon as any current flows in either transistor, this current becomes base current for the other transistor, and both transistors turn on hard. This means you can only build up this circuit using low-leakage transistors ('though this should be the case with any decent- quality modern transistor ).
the best way is to compeair the data sheet of that transistor to the readings of that transistor. . . . .and u can get the readings of that transistor by using a fungction genrator and a c.r.o
When facing the flat side of the transistor, the Emitter - E - is on the left.
Transistor with 2 gate on top and bot of the channel
typically the amplification of a transistor 100 times.
JFET is a unijunction transistor.

UJT(UNIJUNCTION TRANSISTOR) is a three-lead electronic-semiconductor device with only one junction that exclusively as an eletrically controlled swtich andit is not used as a linear amplifier.
No.Di, or bi, means two. A diode, from the Greek di (two), and ode (path), has, rather obviously, two connections, which, in older ones (valves/thermionic diodes), were called electrodes.A transistor has three connections (so it would make, at least grammatic, sense to call it a triode).

There are many different part-numbers found on transistors. These part numbers are to distinuguish individual models for voltage-ratings etc., but there are only two different transistor types; PNP (Positive Negative Posistive), and NPN (Negative Positive Negative)
A Darlington transistor is a composite transistor. The definition is a combination of two or more transistors that have the purpose of increasing the current gain.
Sort of. The Bipolar Junction Transistor, or BJT, is a type of transistor. But the term transistor applies to a much wider family of components than just the Standard BJT. A rough list of the other common types of transistors includes:Field effect transistors, or FETs, including both Junction types and Metal-oxide Semiconductor types: JFETs and MOSFETs. and also UJTs or unijunction transistors.In a basic electronics course, though, if you say just 'transistors' it is assumed you mean BJTs.
Depending on how the transistor is biased and various other circuits connected to it, a transistor acts as an amplifier and/or switch. When acting as an amplifier the circuit containing the transistor can do things like transmit or receive radio signals, perform analog mathematical calculations, generate waveforms, etc. When acting as a switch the circuit containing the transistor can do things like turn on/off a light, turn on/off a motor, perform digital logic or mathematical operations, fetch and decode computer instructions, etc. Exactly what a transistor can do is really only limited by the system requirements and the designer's imagination as to how to meet those requirements. There are several different types of transistors: bipolar junction transistors (BJTs), field effect transistors (FETs), unijunction transistors (UJTs), programmable unijunction transistors (PUJTs), spacitors, surface barrier transistors (SBTs), tetrode transistors (TTs), point contact transistors (PCTs), etc.
