In a proper circuit configuration with two "programming" resistors for setting the parameter η {displaystyle eta } , they behave like a conventional UJT. 50mA PeakPulse Emitter Current (Note 1), IE . 2014 :: DatasheetsPDF.com :: Semiconductors Datasheet Search & Download Site. MENU . Unijunction transistors, retrieved 2014 May 12 . A UJT is operated with emitter junction forward- biased while the JFET is normally operated with the gate junction reverse-biased. 65 to 125C Storage Temperature Range, Tstg . There are three types of unijunction transistors:. ..

For example, they were used for relaxation oscillators in variable-rate strobe lights.[3] Later, as integrated circuits became more popular, oscillators such as the 555 timer IC became more commonly used. type Status report. Cleary (ed.), "General Electric Transistor Manual", General Electric, 1964 Chapter 13 "Unijunction Transistor Circuits" ^ 2N6027, 2N6028 data sheet by ON Semiconductor, at farnell.com ^ Ronald M.
The UJT has three terminals: an emitter (E) and two bases (B1 and B2) and so is sometimes known a "double-base diode". The base 2 is used for applying external voltage VBB across it. The function of the base and the emitter are different from the base and emitter of a bipolar transistor.

VA decreases with the increase in emitter current, and UJT have the negative resistance characteristic. Unijunction transistor circuits were popular in hobbyist electronics circuits in the 1960s and 1970s because they allowed simple oscillators to be built using just one active device.

So the device is not symmetrical, because symmetrical unit does not provide electrical characteristics to most of the applications. Therefore, on each side of the diode, equal voltages results no current flow through it, neither in reverse bias nor in forward bias. The 2N2646 is the most commonly used version of UJT. Use pulse techniques: PW 300s, duty cycle 2.0% to avoid internal heating, which may result in erroneous readings.

A unijunction transistor (UJT) is a three-lead electronic semiconductor device with only one junction that acts exclusively as an electrically controlled switch. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. 4fb9d08492
