The 2EZ51D2/TR12 Zener diode is a single electronic component designed for electrical operations such as voltage regulation, over-voltage protection, transient suppression, and other related functions. It is usually used as a voltage reference and for input protection in applications requiring consistent and reliable operation.

Overview

The 2EZ51D2/TR12 diode is a type of Zener diode, which is an electronic component that regulates and maintains a specific voltage. It acts as a voltage regulator, since it will keep the voltage from deviating from its required level. This property of Zener diodes makes them useful in voltage-controlled circuits and for power management tasks.

Zener diodes are usually used for the protection of electrical devices from over-voltage and conditions such as inductive switching transients. They are also used in current-limiting applications, as well as for voltage regulation in power supplies and automotive electronics.

Characteristics and Features

The 2EZ51D2/TR12 has a maximum operating temperature of 125°C, and a reverse voltage of 9 V at 1 A. It has an operating current range of 4.75 – 7 V, which is adequate for most applications. It has an operating junction temperature range of -55°C to +150°C and a standard testing area of 10 mA.

The 2EZ51D2/TR12 is a low-cost Zener diode that offers a higher degree of reliability than other options. It is able to offer consistent and reliable performance, and its relatively low cost makes it a viable option for many applications.

Application Field and Working Principle

The 2EZ51D2/TR12 Zener diode is generally used as a voltage reference and for input protection in applications requiring consistent and reliable operation. It is designed to maintain the voltage from deviating from its required level when connected to a power source.

In operation, the Zener diode works by allowing current to flow through its P-N junction in the reverse direction when a reverse voltage is applied. As the reverse voltage exceeds the Zener voltage, the voltage on the junction increases, so that the device will not get damaged even if the voltage increases. If the voltage increases further, the current in the diode increases and the voltage across it is clamped to the Zener voltage. In other words, when a reverse voltage is applied, the Zener diode acts as a voltage regulator, maintaining the voltage at its required level.

The 2EZ51D2/TR12 is suitable for various applications, such as protecting electronic equipment from over-voltage and transient conditions, and for voltage-regulating power supplies. It is also used in current-limiting circuits and in automotive electronics. It is one of the most reliable and cost-effective Zener diodes available on the market.
