The CZRA4749-HF is a single zener diode. It is a semiconductor device used in a wide variety of applications. It has a wide operating temperature range and can be used in high temperature applications.

It is a standard type of zener diode. It has one single conduction path, which allows it to provide stable voltage regulation in a variety of applications. The breakdown voltage of this diode is generally between 5 and 7 volts, making it optimal for use in low power, high frequency circuit designs.

Application Field

The CZRA4749-HF is a commonly used diode in many circuits. It is commonly used in radio frequency (RF) and low voltage switch mode power supplies (SMPS). Its low breakdown voltage makes it ideal for use in low power, high frequency circuit designs.

It is also used in linear and switching regulator designs. The low breakdown voltage makes it an excellent choice for use in low power circuit designs, as it can provide a stable voltage source to the power supply. Additionally, its operating temperature range makes it suitable for use in high temperature applications, such as automotive and industrial applications.

The CZRA4749-HF is also commonly used in LEDs, as it can act as a current source. This is because its breakdown voltage is much lower than that of a regular diode, so it can be used to provide a constant voltage source to an LED.

A single zener diode is also used in noise suppression circuits. It is used to protect the circuit from high frequency noises that can affect the performance of the circuit. A single zener diode can be used to provide a stable voltage to the circuit, thus protecting it from noise.

Working Principle

The CZRA4749-HF works on the principle of reverse-bias breakdown. It consists of an intrinsic or delta-doped layer of lightly doped semiconductor material, which allows electrons to flow easily when biased. When a reverse-bias voltage is applied, the current flowing through the diode increases until the diode cannot handle the voltage and the breakdown voltage of the device is reached.

Once the breakdown voltage is reached, the current flowing through the device starts to increase exponentially. This phenomenon is known as Zener breakdown, and it is the key to the efficient operation of this diode. The breakdown voltage of the CZRA4749-HF is generally between 5 and 7 volts.

Once the diode has been subjected to reverse-bias breakdown, the increasing current causes the voltage across the device to drop. This drop in voltage keeps the current flowing through the diode constant, thus providing a stable voltage source to the circuit.

The CZRA4749-HF is a single zener diode. This type of diode has one single conduction path, which allows it to provide stable voltage regulation in a variety of applications. Its wide operating temperature range and low breakdown voltage make it a popular choice for use in low power, high frequency circuit designs.
