UJT Characteristics Laboratory Kit

Product Code : SCL-EAE-11194

The UJT Characteristics Laboratory Kit is a semiconductor electronics laboratory apparatus used to study unijunction transistor behaviour, emitter characteristics, peak-point voltage, valley-point current, negative-resistance region, and relaxation-oscillator principles. It supports practical learning for engineering colleges, polytechnics, ITI/TVET centres, physics laboratories, electronics labs, STEM training centres, distributors, and institutional procurement buyers.

Product Description

The UJT Characteristics Laboratory Kit from Lab Equipments Ambala is best positioned under Physics Lab / Electrical and Electronics / Semiconductor Devices Trainer. A dedicated product page with final product code, UJT device number, emitter supply range, inter-base voltage range, meter arrangement, terminal layout, load components, protection, accessories, and documentation should be confirmed before publishing.

A UJT characteristics kit helps learners observe how emitter current varies with emitter voltage for a fixed inter-base voltage. Depending on the final configuration, the kit may support UJT emitter-characteristics plotting, intrinsic stand-off ratio observation, peak-point and valley-point study, and basic relaxation-oscillator demonstration. The final experiment list should be verified from the supplied manual.

Key Features

• UJT characteristics study: supports practical observation of unijunction transistor emitter-voltage and emitter-current behaviour.
• Peak and valley point learning: helps students identify key UJT operating regions where the final circuit supports measurement.
• Negative-resistance region demonstration: enables understanding of UJT switching behaviour in semiconductor-device experiments.
• Inter-base voltage control: may support variation of base-to-base voltage for UJT characteristics study; confirm final control arrangement.
• Semiconductor devices trainer: suitable for electronics engineering, physics, instrumentation, and STEM laboratory sessions.
• Measurement-compatible setup: may support voltmeter, ammeter, milliammeter, microammeter, multimeter terminals, or built-in meters; confirm final layout.
• Specifications pending: UJT device number, supply ranges, meter ranges, oscillator support, protection, and accessories must be verified.

How to Use the UJT Characteristics Laboratory Kit

1. Place the kit on a dry, stable laboratory bench.
2. Confirm the UJT device number, supply voltage, current limits, meter ranges, terminal identification, and circuit diagram before switching on.
3. Connect the UJT emitter, base-1, base-2, supply, meters, and load components according to the approved wiring diagram.
4. Set the emitter-voltage control and inter-base voltage control to the minimum or recommended starting position.
5. Apply the inter-base voltage within the confirmed safe range.
6. Increase the emitter voltage gradually and record the corresponding emitter current readings.
7. Identify the peak-point and valley-point regions from the observation table and plot the UJT emitter characteristics curve.
8. If oscillator operation is supplied, connect the timing resistor and capacitor only as instructed in the manual.
9. Switch off the supply before changing the UJT device, meter range, control setting, or circuit connections.

Safety note: Use the UJT Characteristics Laboratory Kit only with the confirmed low-voltage DC supply and current-limiting arrangement. Do not connect the experiment circuit directly to mains supply. Observe UJT terminal identification, avoid short circuits, keep terminals dry, do not exceed confirmed emitter or inter-base current limits, and switch off power before changing connections.

Care & Maintenance

• Keep the panel, UJT socket, terminals, switches, meters, controls, and connecting leads clean and dry.
• Inspect device orientation, socket condition, fuse condition, lead continuity, controls, and supply output before use.
• Do not exceed the confirmed UJT voltage, current, inter-base voltage, power dissipation, or meter-range limits.
• Store the kit in a dry, dust-controlled cabinet after laboratory use.

Frequently Asked Questions

What is a UJT Characteristics Laboratory Kit used for?

A UJT Characteristics Laboratory Kit is used to study unijunction transistor emitter characteristics, peak-point voltage, valley-point behaviour, negative-resistance region, and relaxation-oscillator principles in electronics laboratories.

What does UJT stand for?

UJT stands for unijunction transistor. It is a three-terminal semiconductor device commonly used in triggering, timing, pulse generation, and relaxation-oscillator demonstrations.

Which UJT device is supplied with the kit?

The supplied UJT device number is not verified. Confirm the exact UJT type, rating, socket design, and replacement method before publishing or ordering.

Does the kit support relaxation oscillator experiments?

Oscillator support is not verified. Confirm whether the final kit includes timing resistor, timing capacitor, output terminals, waveform observation points, and a relaxation-oscillator circuit.

What readings are recorded during the UJT characteristics experiment?

Students typically record emitter voltage, emitter current, inter-base voltage, peak-point readings, valley-point readings, and curve observations according to the supplied circuit diagram and experiment manual.

Can this kit be connected directly to mains power?

No. The experiment circuit should be used only with the confirmed low-voltage DC supply or approved adapter. Direct mains connection can damage the apparatus and create an electrical hazard.
