A Zener diode is a type of diode that takes advantage of what is known as the Zener breakdown effect. Its use allows designers to create voltage sources and voltage references that provide a stable output voltage over a wide range of input voltage values. The 3EZ120D/TR12 is a single Zener diode that can be used in a wide variety of applications. It has a rated breakdown voltage of 120 volts and is designed to have a maximum reverse current of 3 microamperes, with a maximum reverse power dissipation of 0.5 watts. T The diode also has an ideal reverse recovery time of 20 nanoseconds, while operating temperature range is from -25 to 110 degrees Celsius.

The 3EZ120D/TR12 is also characterized by its stable output voltage and precise current regulation at high frequencies. Additionally, the device features a junction-to-case thermal resistance of 1.3 °C/W, exchangeable for a larger 1.6 °C/W to achieve better thermal performance. This further makes it ideal for use in a wide range of industries, including sensing and control, aerospace, communications, power and industrial applications.

To understand how the 3EZ120D/TR12 works it is important to understand the Zener diode and the Zener effect. Inside the diode is a p-n junction, which consists of a P region of n-type material and an n region of p-type material all within a single semiconductor crystal. As current is applied, the electrons become free and move toward the P region creating a depletion layer across the p-n junction. As the voltage is increased, the electrons will eventually reach the P region and the barrier potential will be exceeded, initiating a reverse current known as the Zener breakdown. This results in the diode becoming a voltage regulator, with the breakdown voltage acting as its constant reference.

The 3EZ120D/TR12 is a single Zener diode that offers a range of features, making it ideal for use in a variety of applications. Its rated breakdown voltage of 120 volts, along with its maximum reverse current of 3 microampere, maximum reverse power dissipation of 0.5 watts, and fast reverse recovery time of 20 nanoseconds make it particularly suitable for protection circuits and for use in systems requiring a reliable and stable reference point. Moreover, its junction-to-case thermal resistance of 1.3 °C/W, and optional 1.6 °C/W are compatible with industrial applications. Thus, the 3EZ120D/TR12 is an excellent choice for a variety of applications demanding a reliable, high-precision, and high-current output with superior protection.
