2EZ18D5E3/TR8

2EZ18D5E3/TR8 devices are a kind of single Zener diodes, which are typically used to provide a reference voltage for many electronic applications. The diode has a series of highly doped PN layers, a PN layer parallel to the junction, and a large area Schottky contact metallization. It is mainly used as a voltage reference in an analog circuit and can also be used to keep an output voltage stable. It is also used to limit the maximum output voltage of any device.

A Zener diode is composed of two parts, namely a silicon diode and a zener junction. The zener junction is composed of N-type and P-type semiconductor layers, forming a PN junction. When a voltage, greater than the Zener threshold voltage, is applied to the diode, the electrons in the N-type semiconductor layer, which are closest to the PN junction, are instantly forced into the junction. This sudden flow of electrons into the PN junction creates a large number of electron-hole pairs in the junction. This process is known as the Zener effect.

The working principle of the 2EZ18D5E3/TR8 is relatively simple. When a forward bias voltage is applied, holes from the N-type substrate and electrons from the P-type substrate are drawn to the PN junction, creating an electric current. When a reverse voltage is applied, and greater than the Zener threshhold, the Zener effect is induced, and a hole-electron pair is formed in the junction, generating an additional current. This additional current helps to maintain the voltage across the diode within the Zener range.

The 2EZ18D5E3/TR8 is usually used as a voltage regulator to maintain a constant voltage in analog circuits. It helps to control the voltage output of power supplies for different types of electrical equipment. It can also be used to limit the maximum output voltage of an electronic device and provide a constant voltage reference for circuit operations. In addition, it can provide protection against excessively high voltages, protecting the electrical equipment from damage or malfunction.

The 2EZ18D5E3/TR8 is widely used in various electronic applications such as computer equipment, audio equipment, automotive electronics, and power supplies. It is also suitable for applications with strong vibration and shock, such as aircraft and defense systems, which require reliable and durable components. It offers excellent temperature coefficient performance, keeping the Zener voltage within the limit specified by the manufacturer. It also offers good mechanical properties, making it a good choice for many applications.

In conclusion, the 2EZ18D5E3/TR8 is a type of single Zener diode which is commonly used in many electronic applications, such as providing a reference voltage, protection against excessively high voltages, and voltage regulation for power supplies. It offers excellent mechanical properties and temperature coefficient performance, making it a good choice for many applications. It can be used in applications which require reliable and durable components, such as aircraft and defense systems.
