PN Junction Diode
Product Code : SCL-EAE-11359
The apparatus provides a structured platform for connecting a PN junction diode to a controlled DC circuit. Students can vary the applied voltage, observe the corresponding current and record the readings required to plot the diode characteristic curve.
The trainer is intended for repeated classroom demonstrations and laboratory practicals. Its panel-based arrangement keeps the diode circuit, controls, terminals and measuring points organised for teaching. The exact meter ranges, power-supply ratings, panel material and supplied diode must be ed against the final technical datasheet.
Key Features
Forward-bias investigation: Helps students observe the increase in diode current after the applied forward voltage reaches the conduction region.
Reverse-bias investigation: Supports observation of the small reverse current within the apparatus’s specified operating range.
V-I characteristic plotting: Provides voltage and current readings for preparing forward and reverse characteristic graphs.
Organised experiment panel: Keeps terminals, circuit sections and controls accessible during supervised practical work.
Hands-on semiconductor learning: Connects diode theory with measurable circuit behaviour.
Teacher-demonstration value: Supports step-by-step explanation of polarity, biasing and current direction.
Institutional application: Suitable for physics laboratories, electronics laboratories and STEM training rooms.

Frequently Asked Questions
What is a PN junction diode apparatus used for?
It is used to measure and plot the relationship between diode voltage and current under forward- and reverse-bias conditions.
What does forward bias mean in a PN junction diode?
Forward bias connects the P-side toward the positive supply and the N-side toward the negative supply. This condition allows significant current to flow after the diode enters its conduction region.
What happens when the diode is reverse biased?
Reverse bias normally produces only a small reverse current within the safe operating region. The apparatus should not be driven beyond its verified reverse-voltage rating.
Can students plot a V-I characteristic curve with this apparatus?
Yes. Students record corresponding voltage and current readings and plot current on the vertical axis against voltage on the horizontal axis.
Is the PN Junction Diode Apparatus suitable for schools?
Yes. It supports supervised semiconductor experiments, physics demonstrations and introductory electronics practicals.
Are meters and connecting leads included?
The supplied meter configuration and accessories have not been verified. the complete kit contents in the final quotation.
