Hi T-bro, no matches in datasheet search engines found. You must log in or register to 2n48991 here. Published under the terms and conditions of the Design Science License.
After capacitor discharge, the operating point resets back to the slope up to the peak point. To participate you need to register.
The characteristic curve for the programmable unijunction transistor in Figure above is similar to that of the unijunction transistor. See Figure below a. Boncuk New Member Jul 24, Please post a schematic for further help.
The Unijunction Transistor (UJT)
PUT timing circuits are said to be usable to 10kHz. As anode current inceases, voltage increases up to the peak point. This will raise the lower limit on the resistor range a little. If the charging resistor ever could supply that much current, the resistor would daasheet 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.
The schematic symbol is Figure below c Unijunction transistor: Quote of the day. It is inexpensive and in production.
Just saying dahasheet Started by MichaelaJoy Yesterday at 6: Started by fastline Yesterday at datxsheet The relaxation oscillator in Figure below is an application of the unijunction oscillator.

If a linear ramp is required instead of an exponential ramp, replace the charging datsheet with a constant current source such as a FET based constant current diode. Figure below show the PUT relaxation oscillator with the final resistor values.
What is the range of suitable values for R in Figure abovea relaxation oscillator? A unijunction transistor is composed datsheet a bar of N-type silicon having a P-type connection in the middle.
Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Use any Unijunction Transistor. PUT relaxation oscillator Problem: PUT relaxation oscillator with component values.
The voltage reaches a minimum at the valley point. T-bro New Member Jul 24, The charging resistor R E must fall within certain limits. We still need V Vthe valley voltage.
