Quick Answer: The Digital Zener Diode Apparatus is an electronics trainer for plotting the forward and reverse V-I characteristics of a Zener diode and studying breakdown voltage and voltage regulation.
Last updated: October 2026
Key Features
- Plots forward-bias and reverse-bias V-I characteristics
- Identifies the Zener breakdown region in reverse bias
- Shows how a Zener diode can hold a near-constant voltage in suitable circuits
- Supports study of dynamic resistance and current limiting
About This Product
Starting from the lowest safe supply and current settings, students record diode voltage and current at a series of settings, first in forward bias and then in reverse. The reverse curve shows the Zener region, which leads into how the device works as a voltage reference. It suits semiconductor lessons in physics, electronics and electrical engineering laboratories.
Frequently Asked Questions
Q1. What is the Zener breakdown voltage?
It is the reverse-bias voltage at which breakdown occurs. On the reverse characteristic this appears as the Zener region, where the voltage stays nearly constant.
