Quick Answer: The Zener Diode Unit is a teaching unit for demonstrating reverse breakdown and voltage regulation, showing how a Zener diode conducts at its breakdown value and helps hold a near-constant voltage.
Last updated: October 2026
Key Features
- Demonstrates reverse-bias breakdown at the Zener voltage
- Helps maintain a near-constant voltage across its terminals within rated limits
- Introduces voltage reference, clipping and overvoltage protection
- Allows comparison of ordinary diode and Zener diode operation
About This Product
With a series resistor to limit current, the unit is connected in reverse bias to the teacher's circuit diagram and a voltmeter is placed across it. Students raise the input voltage within the safe range and record voltage and current, seeing the voltage across the diode level off once breakdown is reached. It supports basic electronics lessons on regulation and semiconductor devices.
Frequently Asked Questions
Q1. How is it different from an ordinary diode?
In reverse bias, a Zener diode conducts once the reverse voltage reaches its breakdown value and then helps keep the voltage across it nearly constant, within its rated limits.
