Zener Diode Unit Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12409

The Zener Diode Unit is a physics and electronics teaching apparatus used for demonstrating reverse breakdown, voltage regulation and semiconductor diode behavior in classroom circuits. It is suitable for schools, colleges, STEM laboratories and physics teachers who need a practical unit for teaching Zener voltage and circuit protection concepts.

Product Description

The Zener Diode Unit from School Equipments helps students study how a Zener diode behaves differently from an ordinary diode when connected in reverse bias. When the reverse voltage reaches the Zener breakdown value, the diode conducts and helps maintain a near-constant voltage across its terminals, within its rated limits.

This unit is useful for lessons on diode polarity, reverse breakdown, voltage reference circuits, clipping circuits and basic regulation. It can be used with related electricity and electromagnetism apparatus, physics laboratory equipment, electrical accessories and electrical devices for complete classroom electronics setups.

How to Use the Zener Diode Unit

1. Place the Zener Diode Unit on a dry, stable laboratory table or circuit-board area.
2. Identify the anode and cathode terminals before making any circuit connection.
3. Confirm the Zener voltage and current rating of the supplied unit before powering the circuit.
4. Connect a suitable series resistor to limit current during the experiment.
5. Connect the unit in reverse bias according to the teacher’s circuit diagram.
6. Use a voltmeter across the Zener diode to observe voltage behavior.
7. Increase the input voltage only within the safe range specified for the apparatus.
8. Record voltage and current observations, then switch off the supply before changing connections.

Safety and handling note: never use the Zener diode without current limiting, and do not exceed the confirmed voltage, current or power rating.

Care & Maintenance

• Store the unit in a clean, dry laboratory cabinet after use.
• Keep terminals clean and free from loose wire strands.
• Do not connect the unit directly across a power supply without a current-limiting resistor.
• Inspect terminal labels and connection points before practical sessions or examinations.

Frequently Asked Questions

What is a Zener Diode Unit used for?

A Zener Diode Unit is used to demonstrate reverse breakdown, Zener voltage, voltage regulation and basic semiconductor behavior in school physics and electronics experiments.

Can this unit be used in school electronics practicals?

Yes, it is suitable for school physics labs, STEM classrooms and basic electronics lessons when used with a compatible low-voltage circuit and teacher supervision.

What is Zener voltage?

Zener voltage is the reverse-bias voltage at which a Zener diode begins controlled breakdown and maintains a nearly constant voltage across its terminals, within its rated current range.

Does this product include resistors or connecting wires?

Resistors, connecting wires, meters and power supply are not specified in the supplied product data. The confirmed included component is 1 Zener Diode Unit.

What rating does this Zener Diode Unit have?

The Zener voltage, current rating and power rating are not specified in the supplied data. Confirm the exact rating before publishing, quotation or tender submission.

Why is a series resistor needed with a Zener diode?

A series resistor limits current through the Zener diode. Without current limiting, excessive current can overheat or damage the diode during a reverse-bias experiment.
