Z - Diodes
Z-diodes (formerly: Zener diode) are diodes that are designed to be operated permanently in the reverse direction in the breakdown voltage range. The level of this breakdown voltage UBR is the main characteristic of a Zener diode and is specified for the respective series or the individual article in the data sheet.
The diodes of the manufacturer NAINA Semiconductor consist of glass-passivated chips and are built in highly reliable, robust hermetically sealed package structures. They are mechanically strong and stable under negative environmental conditions.
These components have a very low forward voltage drop and a very fast switching function and thus a better efficiency. The very low forward voltage also reduces the power loss.
Use of Zener diodes
Zener diodes are used in various applications such as voltage clamp applications, photovoltaic solar systems, switching power supplies, rectifiers, detectors, motor drives, etc. We recommend the Z-diodes of the manufacturer NAINA, which can cover the following voltage ranges with its assortment.
- Voltage range: 6.8V - 200V for 10W & 50W
- Voltage range: 7.0V - 75V for 20W & 75W
- Voltage range: 34.5V - 150V for 300W
- Stud-base packages with UNF thread / TO3 housing

Facts about Zener Diodes
In the past, these diodes were named after the American physicist Clarence Melvin Zener, the discoverer of the Zener effect (electrons tunnel through the junction). Since the 1970s, the name Z diode has been recommended because the Zener effect is only responsible for low breakdown voltages. In the forward direction, they behave like normal diodes. In the reverse direction, Z-diodes are reverse-biased at low voltages, just like normal diodes. Above a certain reverse voltage, the so-called breakdown voltage, the current increases by many orders of magnitude within a few hundred millivolts.
