Semiconductor Diode
Semiconductor Diode (Product Code: SCL-443/118) is a two-terminal electronic component used to demonstrate one-way current flow and rectification in physics and electronics laboratories. Offered in different values, it serves students plotting forward and reverse characteristics and building simple rectifier circuits, and it is described as reliable in operation with low maintenance. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for schools assembling a semiconductor diode kit for physics practicals.

What Is the Semiconductor Diode Used For?
A semiconductor diode lets current pass easily in one direction and blocks it in the other. In the lab it is used for the I–V characteristic experiment, where students record current against voltage in forward and reverse bias, and for half-wave and full-wave rectifier demonstrations that turn AC into pulsating DC. It also shows how a circuit can be protected against a reversed battery connection.
Mark the cathode end, usually shown by a band on the body, before wiring, and include a series resistor so forward current stays within safe limits. Forward current rises quickly just above the knee voltage, so taking small voltage steps in that region gives a smoother curve. A milliammeter in series and a voltmeter across the diode give readings that tabulate cleanly.
What to Specify When Ordering
- The diode value or type number your experiment calls for.
- Number of pieces per bench, including spares.
- Whether a PN Junction Diode or Zener Diode is also required for comparison experiments.

Frequently Asked Questions
Which values of Semiconductor Diode are available?
The Semiconductor Diode (SCL-443/118) is offered in different values. Share the type number or rating your experiment uses, and ScienceLab will confirm which values can be supplied before sending a quotation.
What experiment is the Semiconductor Diode used for?
The Semiconductor Diode is used to plot the forward and reverse bias I–V characteristic of a p-n junction and to demonstrate half-wave and full-wave rectification in school and college physics practicals.
How do I identify the terminals of the Semiconductor Diode?
On most semiconductor diodes the cathode is marked by a band on the body and the other end is the anode. For the Semiconductor Diode, confirm polarity with a multimeter's diode test before wiring it into a student circuit.
Does the Semiconductor Diode need maintenance?
The Semiconductor Diode is described as low-maintenance and reliable in operation. Store it dry, avoid bending the leads sharply at the body, and always use a series resistor so that excess current does not damage the junction.
