Diodes - Zener - Single

The CZRER52C2V4-HF are a single Zener diode, commonly used to protect devices against overvoltage transients. The diode can function as either a low voltage voltage regulator, to provide a consistent voltage drop in the presence of varying current flow, or as a temperature compensated shunt regulator, providing a more precise and stable current.

Application Fields

A Zener diode like the CZRER52C2V4-HF can be used to clamp overvoltage spikes, act as an inrush current limiter, or be used in voltage regulation and voltage reference circuits. They can be used to prevent overvoltage damage to sensitive circuits, make sure that a device only sees the correct voltage, or act as a very accurate reference voltage. They have a wide range of applications ranging from power supplies to communications. These diodes can be used in a variety of applications and environments, such as automotive, aerospace, industrial, and communications.

Working Principle

When exposed to reverse biasing, Zener diodes like the CZRER52C2V4-HF use the Zener effect, wherein electrons crossing the junction create a depletion region which will break down at a certain voltage. This breakdown or “knee voltage” can be selected by the user. This breakdown voltage is known as the Zener voltage, and it will remain the same even when the current passing through the device changes. This makes Zener diodes extremely useful for voltage regulation and voltage reference.

When the diodes are operating near their Zener voltage, they should be kept within their specified power dissipation ratings. If the power dissipation is too high, overheating can occur, damaging the diode. To control the power dissipation, the diode can be placed in series with a current-limiting element. This series element ensures the current flowing through the diode is kept within the power dissipation ratings.

When used as a voltage reference, Zener diodes are typically placed in reverse bias. This increases the breakdown voltage and decreases the leakage current. The leakage current also decreases with increasing temperature, making Zener diodes excellent for temperature-sensitive applications.

Conclusion

The CZRER52C2V4-HF is an ideal single Zener diode for protecting circuits from overvoltage transients and for accurate voltage regulation or voltage reference applications. With its wide range of applications and ease of use, the CZRER52C2V4-HF is sure to be the perfect fit for your circuit.
