PN Junction Diode Characteristics Apparatus
Product Code : SCL-EAE-11363
Quick answer: The PN Junction Diode Characteristics Apparatus is a bench trainer with an integrated diode section, biasing controls and two built-in meters for measuring forward- and reverse-bias V-I characteristics. Students tabulate voltage and current, plot the curve and identify the knee region. Lab Exports manufactures it in Delhi for schools, colleges and polytechnics.

How it is used
The PN junction diode characteristics apparatus is a self-contained bench unit: the diode, the biasing controls and two built-in meters sit on one panel, so no separate meters have to be arranged before the practical. Switching the bias from forward to reverse lets students compare how the same junction behaves when its barrier is lowered and when it is raised.
- Place the unit on a dry bench with the controls set to their lowest position.
- Make the forward-bias connection and switch on.
- Raise the bias step by step and enter each pair of meter readings in the observation table.
- Switch off, change to the reverse-bias connection and take a second set of readings.
- Plot both sets as current against voltage and mark the conduction (knee) region.
Instructors use the finished graph to explain conventional current direction, anode and cathode marking, and why a diode behaves as a one-way valve for current in rectifier circuits.

Frequently asked questions
What readings are taken on the PN junction diode characteristics apparatus?
Paired values of diode voltage and diode current at each bias setting, first in forward bias and then in reverse bias. These are tabulated and plotted as the V-I characteristic curve.
Are the meters built into the apparatus?
Yes. Two measuring meters are integrated into the panel, so the practical needs no separate voltmeter or ammeter.
