3EZ36D5E3/TR12

Diodes are one of the most important devices used in electronics. A single Zener diode, type 3EZ36D5E3/TR12, is one example of a diode with useful applications in a variety of fields, and a basic understanding of their working principle can help to unlock their potential. In this article, their application and working principles are discussed in detail.

Zener diodes are used for two primary purposes: to rectify an alternating current, and to regulate a direct current voltage. As a rectifier diode, 3EZ36D5E3/TR12 is used to convert AC current into a DC form by passing current in one direction and blocking current in the opposite direction. The diode works upon specific principles of operation, including the PN junction, to accomplish this rectification. As a voltage regulator, the diode is used to maintain a constant voltage level by allowing current to flow past a certain threshold. This is accomplished by utilizing a phenomenon known as Zener breakdown, in which electrons and holes recombine, creating an avalanche effect that maintains a constant voltage in the reverse direction.

The 3EZ36D5E3/TR12 is capable of operating in temperatures of up to 200 degrees celsius, making it suitable for use in many high-temperature applications. It can be used in automotive circuitry, circuit protection, and UPS systems. It has a wide range of possible applications, including use in low power DC/DC converters, automotive systems, battery backup systems, medical devices, and more.

The working principle of the 3EZ36D5E3/TR12 is based on the property of the PN junction diode. When a voltage is applied, a potential barrier is created between the P and N regions near the junction. If a reverse bias is applied, holes at the P-side and electrons at the N-side are attracted to the junction to create a depletion region. This creates a barrier for current flow in the opposite direction. Zener breakdown occurs when the electric field at the PN junction is strong enough to cause electrons and holes to recombine and generate a powerful current. This current is called “zener current”, which is responsible for maintaining a constant voltage.

In conclusion, the single Zener diode 3EZ36D5E3/TR12 has many valuable applications, be it as a rectifier or a voltage regulator. Its ability to function in high temperatures makes it suitable for a variety of applications in diverse fields. The working principle of the diode relies on the properties of PN junction, and the phenomenon of Zener breakdown to maintain a constant voltage.
