Semiconductor Diodes (for high school) Manufacturer,Supplier and Exporter in India

Semiconductor Diodes (for high school) (Product Code: SCL226/035) are rectifier diodes for practical lessons on one-way conduction, forward and reverse bias, and converting alternating current into direct current. Their 1000 V direct voltage rating and 5 A maximum direct current leave a wide margin for the low-voltage circuits used in school laboratories. These components are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for use in any semiconductor diode kit for physics practicals.

Specifications

Typical Use

The first experiment is usually the simplest: place a diode in series with a small lamp and a cell, then reverse it. The lamp lights one way round and stays dark the other, which makes the idea of forward and reverse bias concrete. With a variable supply, a resistor and two meters, students then record current against voltage and plot the characteristic curve, noting the sharp rise once the forward threshold is passed.

Senior classes use the same diodes to build a half-wave rectifier from a low-voltage AC source, then combine four of them into a bridge for full-wave rectification, a standard rectifier circuit kit exercise. Always include a series resistor to limit current, check the band that usually marks the cathode before connecting, and never feed the circuits directly from the mains.

Supplier

Jain Scientific Equipments Private Limited, known to customers as ScienceLab, operates from Ambala, Haryana and supplies electronic components like these diodes alongside its own physics apparatus, so a school can source a complete practical from one place. Visit the company profile to learn more.

Frequently Asked Questions

What are the diode ratings?
The direct voltage rating is 1000 V and the maximum direct current is 5 A, which comfortably covers low-voltage school circuits.

How many diodes are in each pack?
The pack quantity is not stated on this listing. Please contact us with the number your class needs and we will confirm how they are supplied.

Can they be used to build a bridge rectifier?
Yes. Four diodes arranged in a bridge give full-wave rectification from a low-voltage AC supply; one diode alone gives half-wave rectification.

Do I need a resistor in the circuit?
Yes. A series resistor limits the current, protects the diode and the supply, and gives students a steady reading when plotting the curve.

How do students identify the terminals?
On most rectifier diodes a band on the body marks the cathode. Check the marking on the parts you receive before wiring.

Can you quote for a whole lab or export order?
Yes. Give us the code SCL226/035, the quantity and delivery address; we supply schools in India and international markets.
