Digital PN Junction Diode
Product Code : SCL-EAE-11360
Quick answer: The Digital PN Junction Diode is a training panel for measuring the forward- and reverse-bias V-I characteristics of a diode, with built-in digital voltage and current indication. Students raise the bias step by step, read values directly from the displays and plot the characteristic curve. Lab Exports manufactures it in Delhi for schools, polytechnics and colleges.

How the digital diode experiment is done
With digital indication of both voltage and current, the Digital PN Junction Diode trainer lets students concentrate on the physics of the junction rather than on reading a pointer scale. The DC input to the diode is raised in small steps and each voltage-current pair is read directly from the displays, giving clean data for the V-I characteristic graph.
- Set the trainer on a dry bench, locate the digital displays, diode terminals and bias controls, and turn every control to minimum.
- Connect the diode for forward bias following the supplied circuit diagram and switch on.
- Increase the input in small increments and write down the voltage and current shown on the displays at each step.
- Bring the control back to minimum, switch off and change the connections to reverse bias.
- Take the reverse-bias readings within the rated range and plot both sets on one graph.
The plotted curve shows the knee in forward bias, where current begins to rise sharply, and the very small reverse current below breakdown. Numeric readings make it easier to follow the gradual rise near the knee and to work out the forward dynamic resistance from two closely spaced points.
Key features
- Integrated digital voltage and current indication gives direct numeric readings
- No analogue pointer scale to interpret, so parallax errors are avoided
- Forward-bias and reverse-bias experiments on the same training panel
- Controls, terminals and circuit sections laid out for supervised laboratory work
- Fits semiconductor physics and introductory electronics courses at school, polytechnic and college level
