Diodes Zener are a type of diode that is specially designed to allow current to flow in the reverse direction. The purpose of this type of diode is to regulate the voltage in a circuit, meaning that the voltage remains constant no matter what changes in the current. The CMDZ1L8 TR is one such diode used for this purpose. This article will discuss the application field and working principle of the CMDZ1L8 TR.

Application Field of CMDZ1L8 TR

The CMDZ1L8 TR is mainly used in high-speed power systems, such as electric vehicles, industrial and medical applications, electric locomotive braking systems, motor control applications, as well as in high-speed switching power supplies. These applications require a fast, accurate, and stable voltage regulator with a high break-down voltage.

The CMDZ1L8 TR diode is designed for use in harsh environments, such as for the automotive industry where high temperatures and vibrations can affect the performance and reliability of the components. It is also designed to provide a low forward voltage drop, meaning less power is wasted in the form of heat energy.

Working Principle of CMDZ1L8 TR

The working principle of the CMDZ1L8 TR is based on Zener breakdown theory. When the reverse voltage applied to the diode exceeds the Zener breakdown voltage (VZ), the junction breaks down and current starts to flow in the sawtooth-shaped electric field. The diodes are designed with a break-down voltage between 6.8V and 10V and a reverse current range between 100mA and 250mA.

The breakdown process is self-limiting and the current increases in pulses until it reaches a steady state. The Zener breakdown voltage of the CMDZ1L8 TR can be adjusted by changing the amount of junction doping. As the doping increases, the Zener breakdown voltage increases and so does the peak current.

When the voltage on the diode decreases below the Zener breakdown voltage, the diode’s current decreases. This produces a stable voltage level. The stable voltage is maintained even when the current demand is changed.

Conclusion

The CMDZ1L8 TR is a silicon-based Zener diode that is used in high-speed power systems such as electric vehicles, industrial and medical applications, electric locomotive braking systems, motor control applications, and high-speed switching power supplies. The working principle of the CMDZ1L8 TR is based on the Zener breakdown theory, whereby the diode produces a stable voltage when the voltage applied is above the Zener breakdown voltage.
