CMDZ4L7 TR Application Field and Working Principle

Diodes - Zener - Single

The CMDZ4L7TR is a Zener diode specifically designed for a wide range of applications. It has been developed by Combidyte Corporation, a world leading manufacturer of semiconductor components.

A Zener diode is a semiconductor device that can be used for voltage regulation and protection against reverse correlation. It is made of an n-type and a p-type semiconductor, where the p-type is heavily doped to create a heavily n-type area (“the Zener region”). A Zener diode is effectively a diode for reverse current, and when the voltage on its anode reaches the reverse breakdown voltage (Vz) of the diode, it will conduct current in the reverse direction.

The CMDZ4L7TR is a 4.7 V Zener diode, meaning that the reverse breakdown voltage of the device is 4.7 V. It has a maximum power dissipation of 500 mW and a maximum peak surge current of 1A. It is a two-terminal device, typically packaged in an axial package.

The most common application field of the CMDZ4L7TR is as a voltage regulator and protection device in low-power electronic circuits. It can be used for example to protect components from overvoltage and spikes. It can also be used as a voltage clamp that can shunt a large amount of current from a circuit. It can also be used in high-precision analog circuits as a voltage reference, or to provide desirable current conducting paths at exact voltage levels.

The working principle of the CMDZ4L7TR is relatively simple. When anodes find a forward bias close to its Zener voltage (4.7V), the Zener diode will switch into a breakdown mode and act as a current controlled device. Once the breakdown occurs, electrons in the Zener region will cascade across to the cathode and provide current control. This current control can be used to provide voltage regulation, protection, or reference voltage levels.

In summary, the CMDZ4L7TR is a 4.7 V Zener diode with a maximum power dissipation of 500 mW and a maximum peak surge current of 1A. It is a two-terminal device, typically packaged in an axial package. It is mainly used as a voltage regulator and protection device in low-power electronic circuits, and as a voltage clamp that can shunt a large amount of current from a circuit. The operating principle is based on the Zener effect, where, when a certain voltage level is reached, the diode will start to conduct current in the reverse direction.
