Semiconductor Components Set
Product Code : SCL-CL-12364
Semiconductor Components Set (SKU SCL-CL-12364) is a teaching set of thermistors, photoresistors, a thermal element, a photocell, a diode and transistors, each mounted on its own small labelled panel. Students use it to identify semiconductor devices and to see how their behaviour changes with temperature, light and polarity in Class 12 physics and first-year college electronics. Science Lab Supplies provides the set from Ambala, India for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each component sits on a separate small board with interconnections and printed markings, and printed instructions come with the set. The thermistors are NTC types: their resistance falls as their temperature rises. Each has a resin-coated ceramic disc body with two radial through-hole leads, and both p-n-p and n-p-n transistors are included.

Applications and Experiments for the Semiconductor Components Set
The set gives each learner real devices to handle, name and test. Mounted on panels, the parts connect easily to a DC supply and meter, so classes can compare a thermistor warmed by hand, a photoresistor under a lamp and a diode in forward and reverse bias.
- NCERT Class 12 physics practical: identifying a diode, transistor and resistor-type devices from a mixed collection.
- Class 12 semiconductor electronics: forward and reverse bias of a p-n junction diode.
- B.Sc. physics: measuring how NTC thermistor resistance falls with temperature.
- ITI and diploma electronics: telling p-n-p from n-p-n transistors and checking junctions with a multimeter.
- Light-sensor lessons: resistance of a photoresistor and output of a photocell under changing light.
Standard Scope of Supply
The set comprises thermistors and photoresistors, a thermal element, a photocell, a diode, and p-n-p and n-p-n transistors, each on its own small marked panel, together with printed instructions. A DC power supply, meters and connecting leads are not part of the listed set.
Packing, MOQ and Lead Time
Order a single demonstration set or one per student group; either way the quotation gives packing, delivery time and price for the quantity requested. Power supplies, resistors and leads from the same range can be added, making it simple to source school physics lab equipment in India together.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Send your list via the contact page, build it in the enquiry cart, or read about tender supply on the lab tender page.
Frequently Asked Questions
What does NTC mean on the thermistors?
NTC stands for negative temperature coefficient: the resistance goes down as the thermistor warms up. The set lists types 5D-5/7/9/11/15, 8D-9/11/20, 0D-5/7/11 and 33D-7.
Are both transistor types included?
Yes. The set lists both p-n-p and n-p-n transistors, so students can compare the two polarities and learn to identify each by its junctions.
Who supplies the Semiconductor Components Set?
Science Lab Supplies in Ambala, India is the supplier; it handles quotation, packing and shipment of the set for school laboratories, colleges and tender contractors.
Does the set need a power supply?
Most tests need a low-voltage DC supply and a meter, which are not in the listed contents. They can be quoted with the set, and the printed instructions guide the connections.
Related Electricity Lab Items
To run the semiconductor practicals, the panels need a supply, a switch, leads and reference resistors. These four items from the same range complete the circuit bench and can be quoted together with the components set.
- Power Supply Unit/ Block for DC — low-voltage DC for biasing the devices.
- Resistors with Gradual Increase of Resistance — series resistors to limit current.
- Cables with Clips — quick connections to the panel terminals.
- Circuit Switch — opens and closes the test circuit.
