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. With it, students can identify semiconductor devices and see how their behaviour changes with temperature, light and polarity in Class 12 physics and first-year college electronics. Science Lab Supplies quotes the set from Ambala, India, for school and college laboratories, training institutes, tender contractors and distributors.
Specifications
All parts of this panel-mounted semiconductor set are broken down row by row in the table. In short, each device sits on its own small board with interconnections and markings, the NTC thermistors have resin-coated ceramic disc bodies with two radial leads, both transistor polarities are present, and printed instructions come with the set.

Applications and Experiments for the Semiconductor Components Set
The set gives each learner real devices to handle, name and test. Because the parts are mounted on panels, they can be wired to a DC supply and meter, so a class 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, with the voltage read on a 0–20 V DC Voltmeter.
- B.Sc. physics: measuring how NTC thermistor resistance falls with temperature, powered from the Electronics Lab Battery Eliminator 2A.
- 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, compared with a Compact 4V 100mA Solar Cell Panel.
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 supply, meters and connecting leads can be added to the same quotation when your bench needs them.
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).

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 includes 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 contains 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?
Quotation, packing and shipment of this set are handled by Science Lab Supplies in Ambala, India, for a single school laboratory, a college department or a tender contractor's full list.
Does the set need a power supply?
Most of the tests need a DC supply and a meter to read current or resistance. Both can be added to the quotation together with the set, and the printed instructions guide the connections for each panel.
