Diodes - Zener - Single

The 2EZ19DE3/TR12 is a Zener diode that is normally available in the SOD-123 and DO-35 packages. It is available in voltages ranging from 3.9 to 47Volts and is a two-terminal diode that is used to provide stable, accurate and reliable voltage regulation.

These diodes have many applications, the main one being that they are used extensively in powersupply applications as voltage sources, which makes them highly suitable for all kinds of low-voltage and medium-voltage switch-mode power supplies. Other applications that use Zener diodes include voltage stabilization, voltage references, voltage detection, clamping circuits and peak rectification.

The principle of operation of Zener diodes is closely related to that of an ordinary diode, but the difference is that, for a Zener diode, a reverse voltage is applied to the diode, which is greater than the forward voltage. This means that the electric field at the reverse junction of the diode will be strong enough to cause electrons to be moved across the junction. The movement of electrons causes the voltage to stay below the Zener voltage by a certain amount, thus providing voltage stabilization, which is the main purpose of this diode.

Azere diodes also have some inherent advantages, which include: good stability, low temperature coefficient, good dynamic characteristics, low maximum operating temperature, good dielectric strength, low thermal resistance, and low noise. All these make these diodes one of the most cost-effective components for voltage regulation.

In summary, the 2EZ19DE3/TR12 is a Zener diode that is useful for providing stable and accurate voltage regulation. It is available in a variety of packages, voltages, and sizes and has a wide range of advantages and applications. By using this diode, a variety of low-voltage and medium-voltage switch-mode power supplies can be built and controlled accurately.
