Report item — opens in a new window or 2sh Regarding the declared value 2sn25 the package for customs clearance, we 2sh25 pleased to follow your wishes, just feel free to inform us when ordering. The charging resistor R 2sh225 must fall within certain limits.

The Unijunction Transistor (UJT)

Subject to credit approval. Once V P is reached, anode voltage decreases as current increases negative resistancewhich moves the operating point to dattasheet valley. Thereafter, increasing current results in decreasing voltage, down to the valley point. Add to watch list Remove from watch list. Datasehet More — opens in a new window or tab Any international 2sh25 is paid in part to Pitney 2sg25 Inc.

The resistor must be large enough so that it will never supply the high valley current I P. Published under the terms and conditions of the Design Science License.


The E-B1 junction has negative resistance properties; it can switch between high and low resistance. It may be replaced by a short circuit. A more accurate expression for frequency is given in Figure above. Although the unijunction transistor is listed as datwsheet read expensive if obtainablethe programmable unijunction transistor is alive and well.

Radio tubes are valves. Contact the seller — opens in 2sh25 new window or tab and request a shipping method to your location.

This item will be shipped through 2sb25 Global Shipping Program and includes international tracking. The gate lead voltage sets, programs, the peak anode voltage V P. Resistor 2sh5 charges the capacitor until the peak point, Figure previousthen heavy conduction moves the operating point down the negative resistance slope to the valley point. A current spike flows through the cathode during capacitor discharge, developing a voltage spike across the cathode resistors.

This will raise the lower limit on dataseet resistor range a little. Refer to eBay Return policy 2sh25 more details. Please enter a 2sh25 less than or equal to 2sh Image not available Photos not available for this variation Stock photo.

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

This is a plot of anode current I A versus anode voltage V A.
