PN Junction Diode
PN Junction Diode (Product Code: SCL-433/113) is a semiconductor diode experiment kit used to study a PN junction diode in forward and reverse bias in school and institute physics labs. Two round meters on the board measure voltage and current, knobs set the applied voltage, and an inbuilt IC-regulated power supply provides the DC. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the PN Junction Diode Apparatus Used For?
In forward bias, students raise the voltage with the knobs and see that almost no current flows until the knee voltage, after which the current climbs steeply. In reverse bias only a very small current flows. Plotting both sets of readings gives the diode's V-I characteristic curve, from which students find the knee voltage and the forward resistance.
With the supply and meters built in, the kit sets up quickly and is portable enough to move between rooms. Begin each run at the lowest voltage setting, change the voltage slowly near the knee, and switch between forward and reverse connections only with the voltage turned down. It is a standard semiconductor diode kit for physics practicals, and pairs well with a Zener diode kit.
OEM Manufacturer
Jain Scientific Equipments Private Limited trades as ScienceLab and is the OEM (original equipment manufacturer) of this PN Junction Diode apparatus. It is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, then supplied factory-direct to schools, institutes, dealers and importers. Institutional and tender buyers who need vendor registration details can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. See the ScienceLab company profile.

Frequently Asked Questions
What does the PN Junction Diode apparatus measure?
The PN Junction Diode apparatus (SCL-433/113) measures the current through a semiconductor diode at different applied voltages in forward and reverse condition. Its two round meters, a voltmeter and an ammeter, give the readings used to plot the diode's V-I characteristic.
Does the PN Junction Diode kit need a separate DC power supply?
No separate DC supply is needed for the PN Junction Diode kit because it has an inbuilt IC-regulated power supply, with voltage set by the knobs on the board. Confirm the mains input required through the ScienceLab contact page when you request a quotation.
Is the PN Junction Diode apparatus portable?
Yes, the PN Junction Diode apparatus is described as portable and easy to use in physics and electronics lab experiments in schools or institutes. With meters and supply on one board, it can be moved between labs and set up quickly.
How should the PN Junction Diode kit be used safely?
Start the PN Junction Diode kit at its lowest voltage setting, increase the voltage slowly while watching the ammeter, and change between forward and reverse connections only with the voltage turned down. Switch off and disconnect the kit after each practical.
Who manufactures the PN Junction Diode apparatus?
The PN Junction Diode apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Schools, institutes, dealers and importers receive quotations and repeat supplies direct from the manufacturer.
Can calibration details be provided for the PN Junction Diode meters?
Calibration-certificate availability for the PN Junction Diode meters should be discussed with us before you order. State the requirement and any meter ranges your syllabus needs in your enquiry, and the manufacturer's quotation will confirm what can be supplied.
