Pin Configuration 2N is a three terminal device ujjt the conductive case also connected to a terminal. The capacitor C1 is for triggering the UJT and resistor R3 is for limiting the flow of charge to capacitor. When the power just turned ON, the UJT will be in high resistance state and total supply voltage appears across it. The device is preferred in other applications 2b guaranteed minimum pulse amplitude is required and also where a low emitter leakage current and a low peak point emitter current trigger current are required.

The device is popular as a triggering device and is not suited for driving power loads. With completion of capacitor discharge the UJT will again return to normal OFF state and will stay in that state until the capacitor discharges again.

Under such case we will have VB2 or UJT voltage drop taking a sharp dip as shown in graph and at other hand because of current flow a voltage appears across R2 VB1 there by producing a sharp pulse voltage as shown in graph. This cycle of capacitor charge and discharge form a triggering cycle for the UJT to datasbeet voltage pulses at the output or VB2. By this vatasheet have UJT acting as an oscillator giving voltage pulses at the output and in a similar way we can use the device in other application circuits.

Submitted by admin on ratasheet November Pin Configuration 2N is a three terminal device and the conductive case also connected to a terminal. TL — Programmable Reference Voltage. With this current flow at the emitter the UJT will get from high resistance to low resistance state and there by acting as a short circuit. Once the capacitor gets charged to threshold voltage at a certain time T1, it will discharge by forcing the current through emitter of the UJT.

The capacitor C1 is for triggering datashewt UJT and resistor R3 is for limiting the flow of charge to capacitor. With the flow of time the capacitor gets charged as the current flows through R3 to reach the capacitor. When the power just turned ON, the UJT will be in high resistance state and total supply voltage appears across it.

How to use 2N Transistor 2N has dataheet application circuits but for understanding the working let us consider the relaxation oscillator circuit of the device. Working When the power just turned ON, the UJT will be in high resistance 2nn and total supply voltage appears across it.

How to use 2N Transistor 2N has many application circuits but for understanding the working let us consider the relaxation oscillator circuit of the device. In the above circuit we are working 2N as a relaxation oscillator to produce trigger pulses or oscillations. The capacitor C1 is for triggering the UJT and resistor R3 is for limiting the flow of charge to capacitor. The circuit is powered from single power source of VCC. Working When the power just turned ON, the UJT will be in high resistance state and total supply voltage appears across it. With the flow of time the capacitor gets charged as the current flows through R3 to reach the capacitor.
