Diodes are a vital component used in the development of electronic designs. One type of diode, the Zener diode, is specially designed for applications that require electrical breakdown and reverse blocking for voltage regulation. In this article, we will discuss the application and working principle of the 2EZ19D5/TR8 Zener diode.

The 2EZ19D5/TR8 Zener diode belongs to the single diode category. This diode is designed to regulate the flow of reverses in circuits and is ideal for applications with over-voltage and over-current protection. The diode has a maximum Zener voltage of 9.1V and can handle a maximum reverse power of 500mW. It has maximum operating junction temperature of 150°C with a breakdown voltage of 7.1V, and a reverse current of 9mA.

2EZ19D5/TR8 Zener diodes typically come in a variety of packages, such as DO-35, SOT-23 and two-pins (metal-thru). These diodes are appropriate for any application with tight space requirements or a minimum mounting area. The diode features low thermal resistance and excellent reliability for an effective, long-lasting operation.

In terms of working principle, the 2EZ19D5/TR8 Zener diode works similar to a regular diode. When voltage is applied to the diode, current will flow from the anode to the cathode in a forward bias direction. With larger voltages, the Zener diode will become forward-biased and the current flowing through it will increase, triggering the Zener breakdown. This breakdown allows the flow of current in the reverse bias direction, controlling the voltage level.

The Zener diode has a wide range of applications, such as in voltage-regulated power supplies, AC-DC rectifiers, RF amplifiers, amplitude modulation circuits, and more. It can also be used in high-voltage regulator circuits and can be connected parallel to other components to absorb transient surge and protect them from voltage spikes. This type of diode also finds use in medical electronics, automotive applications, motor control circuits and switch mode power supplies (SMPS).

The 2EZ19D5/TR8 Zener diode is seen as one of the most reliable components for applications that involve power supplies and voltage regulation. With its low thermal resistance and ability to handle up to 500mW of power at temperatures of up to 150°C, this diode is a popular choice for many applications. Its fast Zener breakdown also makes it an excellent choice for over-voltage and over-current protection for a wide range of electronic designs.
