2EZ12DE3/TR8

Diodes - Zener - Single - 2EZ12DE3/TR8 Application Field and Working Principle

2EZ12DE3/TR8 is a single Zener diode from NXP Semiconductors that is used in multiple applications. It’s a low voltage Zener diode offering ultra-low leakage and fast switching for portable applications such as mobile phones. It features excellent capability to overcome current and power problems that have hampered portable device performance. This Zener diode is available in SC-74A, SOT-343, SOT-323, and DFN packages.

The 2EZ12DE3/TR8 Zener diode provides oversurge protection, reverse power protection and reverse biasing protection, making it great for battery-powered applications. The Zener voltage is set between 6.8V, 8.2V and 9.1V. The maximum reverse current is 30mV, while the maximum power dissipation is 45mW.

The working principle of a Zener diode is the same as that of a standard PN junction diode: When the applied voltage is lower than the Zener breakdown voltage, the diode will remain reverse-biased and no current will flow through it. When the applied voltage exceeds the Zener voltage, it enters Zener breakdown, and the reverse current flows through it, causing the Zener diode to conduct.

2EZ12DE3/TR8 is an ideal protection solution for applications such as smart meters, phones, tablet PCs and other portable devices. Its fast response time and low leakage current make it a great choice for pre-charge circuits, overvoltage protection, switch mode power supplies and low voltage power supplies.

In summary, the 2EZ12DE3/TR8 is a low-voltage Zener diode offering excellent performance and reliability. It provides overvoltage protection and reverse biasing protection, making it great for portable applications. It has a wide range of applications in pre-charge circuits, switched mode power supplies, overvoltage protection and low voltage power supplies.
