Zener Diode Unit Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11266
The Zener Diode Unit provides a practical platform for demonstrating how a Zener diode behaves in an electrical circuit. In forward bias, a Zener diode operates similarly to a conventional semiconductor diode. In reverse bias, it is designed to conduct after the applied voltage reaches its specified Zener breakdown voltage.
The unit can be connected to a suitable regulated DC power supply, current-limiting resistance and measuring instruments. Its exact diode model, Zener voltage, power rating, terminal arrangement, construction material and included circuit components must be confirmed from the approved product specification before publication or use.
Key Features
Zener diode demonstration: Supports practical study of forward-bias and reverse-bias diode behaviour.
Breakdown-voltage investigation: Allows learners to identify the voltage region in which reverse conduction begins.
Voltage-regulation learning: Helps demonstrate how a Zener diode can maintain an approximately stable voltage under suitable circuit conditions.
Measurable circuit response: Can be used with compatible meters to record diode voltage and current.
Semiconductor teaching aid: Converts theoretical diode characteristics into observable laboratory results.
Classroom-compatible format: Suitable for supervised demonstrations and student practical sessions.
Reusable apparatus: Supports repeated experiments when operated within the confirmed electrical ratings.

What's Included in the Kit
1 × Zener Diode Unit
A power supply, current-limiting resistor, connecting leads, meters and experiment manual are not confirmed as included. Verify the complete supply scope before ordering.
Applications / Uses
Plotting the forward-bias characteristics of a Zener diode.
Studying reverse current below the Zener breakdown region.
Determining the approximate Zener breakdown voltage.
Observing the relationship between diode voltage and current.
Demonstrating basic shunt voltage regulation.
Comparing ordinary diode and Zener diode operation.

How to Use the Zener Diode Unit
Identify the anode and cathode terminals marked on the unit.
Confirm the Zener voltage, current limit and power rating of the installed diode.
Keep the regulated DC power supply switched off while connecting the circuit.
Connect a suitable current-limiting resistor in series with the Zener diode.
Connect the diode in forward or reverse bias according to the selected experiment.
Connect an ammeter in series and a voltmeter across the diode where required.
Increase the supply voltage gradually and record the corresponding readings.
Switch off the supply before reversing polarity or changing connections.
Safety note: Never operate the diode without suitable current limiting. Excessive reverse current or operation beyond the rated power can permanently damage the Zener diode.
Care & Maintenance
Store the unit in a dry, dust-free laboratory cabinet.
Inspect the terminals, diode mounting and connecting points before use.
Use only compatible low-voltage DC supplies and suitable series resistance.
Do not pull leads by their wires or apply mechanical force to the terminals.

Frequently Asked Questions
What is a Zener Diode Unit used for?
A Zener Diode Unit is used to study diode characteristics, reverse breakdown and basic voltage regulation in an educational circuit.
What is Zener breakdown voltage?
Zener breakdown voltage is the reverse voltage at which a Zener diode begins to conduct significantly while maintaining an approximately stable voltage across it within its rated operating range.
Can this unit demonstrate voltage regulation?
Yes. It can support a basic shunt-regulator experiment when connected with a suitable supply, series resistor and load circuit.
Is the Zener Diode Unit suitable for schools?
Yes. It is suitable for supervised semiconductor experiments in senior school, college, university and technical training laboratories.
Why is a resistor connected in series with the Zener diode?
The series resistor limits current through the diode. Without adequate current limiting, the diode can overheat and fail.
Are meters and a power supply included?
Only the Zener Diode Unit is confirmed from the supplied information. Meters, leads, resistors and the power supply must be confirmed separately.
