The 2EZ200D/TR8 is a single Zener diode designed for use in voltage regulating and clamping applications. This diode is designed for use with voltage ratings of 5.1 volts and higher. Its reverse breakdown voltage is from 5.1 volts to 6 volts.

General Description

The 2EZ200D/TR8 is a single Zener diode designed for use in voltage regulating and clamping applications. It is manufactured using a diffused NPN planar junction technology and a nitride passivated semiconductor surface. The device is available in the SOIC-8 package and uses the convenient through-hole mounting system.

Features and Benefits

The 2EZ200D/TR8 is designed to provide lots of features and benefits. It offers excellent reverse breakdown voltage up to 6V and its performance increases with temperature. This diode also has an exceptionally low forward voltage drop of 0.3V and low thermal resistance. It also offers good stability and high efficiencies, making it ideal for use in a wide range of applications.

Applications

The 2EZ200D/TR8 is suitable for use in a variety of applications. It is most commonly used in voltage regulation and low-dropout voltage regulation; for example, in power management systems, in dc–dc converters and in chargers for mobile devices. It also finds use in short-circuit and transient protection applications. Additionally, this diode has also become widely used in the manufacture of automotive electronics, audio amplifiers and many other power products.

Working Principle

The 2EZ200D/TR8 works on the principle of Zener conduction, in which the reverse breakdown voltage of the diode is used to produce a constant-voltage regulation. The device has been designed to operate under its forward breakdown voltage and so it bypasses some of the supply voltage to provide a regulated voltage output. When the power supply voltage exceeds the breakdown voltage of the diode, then it breaks down and starts to limit the total current provided by the supply. This current is then limited to a level determined by the designated maximum reverse leakage current of the diode. The result is the supply voltage being propped up to the required regulated voltage.

In summary, the 2EZ200D/TR8 is a single Zener-diode designed for use with voltage ratings of 5.1 volts and higher. It is widely used in voltage regulation, low-dropout voltage regulation, short-circuit and transient protection applications. This device works on the principle of Zener conduction in which the reverse breakdown voltage of the diode is used to produce a constant-voltage regulation. Thanks to its features and benefits, it has become the preferred choice of diode for many applications.
