How Does It Compare with Other JLab Zener Apparatus?
| Model | Diodes | Supply and meters (as listed) |
|---|---|---|
| This apparatus (EL-SCD-1084) | Zener diodes | One DC regulated supply, 0–25 V DC, 15 mA; two meters |
| PN Junction and Zener Diode Characteristics Apparatus | PN junction diode and zener diode | Two DC supplies; two double-range meters |
| Training Board for Diode and Zener Diode | Germanium diode and zener diode | Continuously variable regulated supply with integral current-limiting resistor; digital voltmeter and current meter |
Choose this apparatus when the practical concentrates on the zener diode alone. The PN junction and zener model lets students compare an ordinary junction diode with a zener on the same bench, and the training board does the same with a germanium diode on digital meters.
What Is the Zener Diode Characteristics Apparatus Used For?
A zener diode is a heavily doped silicon junction built to operate in reverse breakdown. In forward bias it behaves like an ordinary diode, conducting once the knee voltage is passed. In reverse bias only a very small current flows until the zener (breakdown) voltage is reached; after that the current rises sharply while the voltage across the diode stays almost constant. Students step the supply in both directions, record voltage and current on the two meters, and plot the full V–I curve, marking the knee voltage, the breakdown voltage and the zener (dynamic) resistance taken from the slope of the breakdown region. Low-voltage zeners break down mainly by the zener effect and higher-voltage ones by avalanche multiplication.
That steady breakdown voltage is why zeners are used as voltage references and simple regulators, the subject of the Voltage Stabilization apparatus that usually follows. The experiment is part of B.Sc. physics and electronics practicals, electronic devices labs in engineering and polytechnic courses, and ITI electronics training. Keep the reverse current within the diode’s rating by raising the supply slowly near breakdown, and switch off before changing connections.
What to Specify When Ordering
- Zener ratings and spares — the listing does not state the zener voltages fitted; ask for them and order spare diodes.
- Meter ranges — request them if your worksheet uses fixed ranges.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
What does this apparatus plot?
The forward and reverse V–I characteristics of zener diodes, using its regulated supply and two meters.
What power supply is built in?
A DC regulated power supply of 0–25 V DC at 15 mA, connected through terminals with the meters and diodes.
Which zener voltages are supplied?
The listing mentions zener diodes mounted on the panel but not their ratings. Ask JLab for the zener voltages when requesting a quotation.
How does it differ from the voltage stabilization apparatus?
This unit plots the zener’s V–I curve. The Voltage Stabilization Characteristics of Zener Diode apparatus uses the zener as a regulator and studies how the output voltage changes with input and load.
What is the minimum order and dispatch time?
The minimum order is 10 units, and dispatch is usually within 7–10 working days after visual inspection. Export transit depends on the destination.
Who manufactures this apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronic lab instruments manufacturer in India, incorporated in 2017 and situated on Hargolal Road, Ambala, Haryana. The zener apparatus is manufactured in JLab’s own works, not sourced through a trader, so colleges, institutes, dealers and importers buy direct; each unit is visually inspected before dispatch, and repeat orders and spare diodes are handled by the manufacturer. The company holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — Luxembourg in Western Europe, the UAE in the Middle East, Slovenia in Southern Europe, Cambodia in Southeast Asia and Nepal in South Asia are examples. Tender information is on the JLab lab tenders page.
