Diodes - Zener - Single

The 3EZ190D10/TR12 is a zener diode designed specifically for single applications. It has a breakdown voltage of 10V, with a package type of 3-pole. This is a popular diode used in commercial and industrial applications, primarily as a voltage reference, voltage regulator, and as a current limiter. It is also used as frequency-controlled switching elements.

Application fields

The 3EZ190D10/TR12 is often used in voltage regulation and voltage reference applications. Its breakdown voltage of 10V makes it ideal for stabilizing the output of power supplies. It can also be used in switching systems, as it can control the motor speed of high-speed machinery. Additionally, in frequency-dependent switching elements, the 3EZ190D10/TR12 can be used to control the frequency of audio and video signals, thus ensuring high-quality sound and images.

The 3EZ190D10/TR12 is also used in automotive applications, such as controlling turn signals or speedometers. It is also commonly used in pilot lamps and indicator lights.

Working Principle

The working principle of a zener diode is based on the fact that when a voltage greater than its breakdown voltage is applied, the diode conducts current in both directions. This occurs because the current is being redirected within the diode, which causes a drop in voltage when the current passes through it in the reverse direction from normal. The 3EZ190D10/TR12 has a breakdown voltage of 10V, which affects the voltage that is applied to it and result in a stable output voltage.

When the voltage applied to the diode is greater than its breakdown voltage, the diode allows a forward current to flow and reverse current starts to flow in the opposite direction. The amount of reverse current flowing depends on the voltage applied to the diode and the number of diodes in series. The higher the number of diodes, the higher the voltage can be applied. The reverse current flow creates a voltage drop across the diode, which results in a stable output voltage.

In general, the objective of using a Zener diode is to regulate the output voltage by connecting the diode in reverse bias with the positive of the output voltage connected to the cathode and the negative of the output voltage connected to the anode.

Conclusion

The 3EZ190D10/TR12 is a widely used zener diode designed specifically for single applications, with a breakdown voltage of 10V. It is used primarily as a voltage regulator, voltage reference, frequency-controlled switching element, and current limiter. In the automotive industry, it is used to control turn signals, speedometers, and indicator lights. Its working principle is based on the fact that when a voltage greater than its breakdown voltage is applied, the diode conducts current in both directions, resulting in a voltage drop that creates a stable output voltage.
