Diodes - Zener - Single

A typical example of a single Zener diode is the CMOZ27V TR. This diode is used in the most general applications such as a voltage reference, protection, wave shaping, and temperature coefficienting. It is popularly used in automotive, computer, industrial, communication, and consumer electronic applications.

Voltage Reference Applications

The CMOZ27V TR can be used in various voltage reference applications. By connecting the diode to a constant voltage source, the CMOZ27V TR creates a stable reference voltage, which can be used to supply a standard or reference voltage to other components. This is especially useful in applications such as automotive electronics, computers, and communication systems.

Protection Applications

The CMOZ27V TR can also be used in protection applications. It can be used to prevent overvoltage conditions by shunting any excessive current away from a sensitive circuit. This will prevent damage to the circuit and the connected components.

Wave Shaping Applications

The CMOZ27V TR can also be used for wave shaping applications. By connecting the diode to an AC voltage source, the diode creates a rectified output waveform. This waveform can then be used for various applications such as filtering, rectification, and signal conditioning.

Temperature Coefficient Applications

The CMOZ27V TR can also be used in temperature coefficienting applications. By connecting the diode to a reference voltage source, its operating temperature can be determined. This temperature can then be used to adjust the operating parameters of components or circuits as required.

Working Principle

The CMOZ27V TR is a voltage dependent device, meaning that it will conduct current when the applied voltage across its terminals reaches the Zener voltage. When the reverse voltage reaches the Zener voltage, the reverse current will flow through the diode and the voltage across the terminal will remain at the Zener voltage. If the voltage becomes higher than the Zener voltage, the diode will break down and the reverse current will increase exponentially. It is important to note that the Zener voltage of the diode is temperature dependent, and the Zener voltage should be used as a reference when selecting a diode for a specific application.

Conclusion

The CMOZ27V TR single Zener diode is a versatile component which can be used in a variety of applications. It can be used in voltage reference, protection, wave shaping, and temperature coefficienting applications. Its working principle consists of it conducting current when the voltage across its terminals reaches the Zener voltage, and the Zener voltage is temperature dependent.
