The device uses a high-efficiency Zener diode, which is encased in a rugged small bodied TO-92 (transistor outline) plastic case, and is ideal for use in low-current switching applications. It is also suitable for reverse current protection and input/output protection.

Applications

The 2EZ4.7D10/TR12 is designed for use in power supplies, antenna protection, low-current switching applications, reverse current protection, and input/output protection. It is suitable for a wide range of DC regulation and protection applications. Its miniature size makes it ideal for use in small form-factor electronic systems, such as embedded systems, mobile phones, and automotive applications.

Working Principle

The 2EZ4.7D10/TR12 is a high-efficiency Zener diode that operates based on the principle of avalanche breakdown. When a reverse voltage is applied across the diode, electrons are accelerated by the electric field created by the voltage until they reach a level where they can cause an avalanche breakdown within the depletion region. This causes the voltage to drop, regulating the voltage to a specific level. The Zener voltage of the 2EZ4.7D10/TR12 is 4.7V.

Features and Benefits

The 2EZ4.7D10/TR12 has a number of features and benefits that make it an ideal solution for various applications. It is a robust device with an average reverse current of 4.5 mA, a voltage regulation ratio of 5%, and a maximum power dissipation of 150 mW. It is also able to withstand temperatures of up to 125°C without any damage. Additionally, the device offers excellent surge protection and has a fast response time to transient conditions. As it is a miniature device, it is ideal for use in embedded and automotive applications, where space is at a premium.
