The schematic symbol is Figure below c Unijunction transistor: The gate lead voltage sets, programs, the peak anode voltage V P. A unijunction transistor is composed of a bar of N-type silicon having a P-type connection in the middle.

The variable resistor should have a minimum resistor in series with it to prevent a low datasheeh setting from hanging at the valley point.

The charging 2sh5 R E must fall within certain limits. See all condition definitions — opens in a new window or tab 2sh25 who viewed this item also viewed. The item may be a factory second or 2sh25 new, unused item with defects. Though it serves a function similar to the unijunction transistor, the PUT is a three terminal thyristor.

The charging resistor must be small enough to supply enough current to raise the anode to V P the peak point Figure previous while charging the capacitor. It is the job of the capacitor to supply the valley current I V.

The PUT shares the four-layer structure typical of thyristors shown in Figure below. If the charging resistor ever could supply that much current, the resistor would supply the valley current after the capacitor was discharged and the operating point would never reset back to the high resistance condition to the left of the peak point.


Once V P is reached, anode voltage decreases as current increases negative resistancewhich moves the operating point to the valley. Refer to eBay Return policy for more details.

Once it is discharged, the operating point resets back to the upward slope to the datsaheet point. S2h25 are 10 items available. Radio tubes are valves. Characteristic curve, internal construction, schematic symbol. Seller assumes all responsibility for this listing. This circuit needs a V BB unfiltered datwsheet not shown divided down from the bridge adtasheet to reset the relaxation oscillator after each power zero crossing.

The characteristic curve for the programmable unijunction transistor in Figure above is similar to datashete of the unijunction transistor.

United States and many other countries See details Import charges: The Unijunction emitter current vs voltage characteristic curve Figure below a shows that as V E increases, current I E increases up I P at the peak point. A current spike flows through the cathode during capacitor discharge, developing a voltage spike across the cathode resistors.
