Diodes - Zener - Single

The CMOZ4V7 TR is a single zener diode, an electronic component which is used in many different applications. This particular diode is commonly used in isolated power systems and LCD drivers, as well as for protecting powered circuit boards against excessive overvoltage. The device is capable of regulating voltage levels up to 4.7 volts.

Device Construction

The CMOZ4V7 TR is primarily constructed from a zinc oxide body and several other components. It also includes an anode and a cathode, both of which are made of heavy metals. The anode is attached to the positive voltage rail in order to provide a connection with the external power source. The cathode is then attached to the circuit\'s ground, completing the circuit.

Working Principle

A zener diode functions by providing a path in which current can flow in a controlled manner, even when voltage levels exceed the device\'s breakdown voltage. This occurs due to the presence of a heavily doped p-n junction within the diode, which becomes active in the presence of an external current and regulates the voltage accordingly. The CMOZ4V7 TR operates in this manner, allowing for the regulation of voltages up to 4.7V.

Applications

The CMOZ4V7 TR is often used in isolated power systems, typically within the PLC and instrumentation markets. The device is commonly utilized in systems which require a single-point output, as well as those which may be subject to high-frequency disturbances. The device is also commonly used as an LCD driver, in order to provide a uniform voltage supply across the LCD display.

The device is also used in the protection of powered circuit boards. In this application, the diode is used as a protective circuit in order to prevent excessive current from entering the system. This is especially useful when it comes to providing protection from overvoltage, as the device can help hold the voltage levels to a safe level before damaging the system.

Conclusion

The CMOZ4V7 TR is a single zener diode which is widely used in several different applications. It is commonly used in isolated power systems and LCD drivers, as well as for providing protection against excessive voltage or current. The diode operates at a regulated voltage of up to 4.7 volts, allowing it to serve multiple purposes in different marked segments.
