3EZ14DE3/TR8 Application Field And Working Principle

The 3EZ14DE3/TR8 is a diode that falls under the Zener Single category. As a general principle, this type of diode is used to regulate voltage by producing a reverse breakdown voltage, and remains operational both in forward and reverse bias. As such, they typically play an important role in circuit protection and peak voltage regulation.

These particular diodes are designed to be through-hole mounted, and can operate spaced apart from the heat-sink due to their low power dissipation. The maximum working voltage is 14V, and is constructed from a high temperature co-fired ceramic body, with a nickel-plated copper lead-frame. The physical dimensions are 4.3mm x 2.3mm.

The primary purpose of the 3EZ14DE3/TR8 diode is to regulate voltage in telecom and switch-mode power supplies, and any other applications that demand precision voltage regulation in a wide range of environmental and temperature conditions. As a low-power device, it may be used in the design of power management equipment, motor control, electronic ballast, and solid-state relays.

The most important feature of the 3EZ14DE3/TR8 is the operating principle of Zener Single diodes. As current flows between the cathode and anode terminals, the diode barrier is slowly destroyed until the zener breakdown voltage is reached. Once this voltage is obtained, a large amount of current passes through the diode, thus creating a low-impedance path - allowing for voltage regulation.

Another key feature of 3EZ14DE3/TR8 is its reverse leakage current. The maximum amount of reverse leakage current is 0.7uA at 25°C, which provides a significant advantage in applications where minimum power dissipation is necessary. The maximum power dissipation for the diode is 300mW, and it operates in temperatures between -55°C to +125°C.

In conclusion, the 3EZ14DE3/TR8 is an important device used in the regulation of voltage in several electronic applications, particularly in telecom and switch-mode power supplies. Its low power dissipation and higher reverse leakage current makes it particularly suitable for such applications, as well as motor control, electronic ballast and solid-state relays.
