Order Zener diodes online

A Zener diode, also known as a Z-diode, is a special semiconductor diode that can be operated in both forward and reverse direction. Unlike conventional diodes, it has a precisely defined breakdown voltage, known as the Zener voltage. Once this voltage is reached, it allows current to flow in the reverse direction. Zener diodes are primarily used for voltage stabilization and to protect electronic circuits from overvoltage. Their high accuracy and reliability make them ideal for demanding applications in industry and electronics manufacturing.

Zener diodes are typically used in the automotive industry, telecommunications, network technology, industrial electronics, and measurement technology. In the automotive industry, they protect electronic control units from voltage spikes. In telecommunications, they are used to stabilize signals. Industrial electronics and measuring devices benefit from the precise voltage reference of Zener diodes, which ensures reliable performance.
