ACZRA4755-HF Application Field and Working Principle

The ACZRA4755-HF stands for Avago High Frequency Zener Diode, and it is a high frequency, small package Zener diode. The ACZRA4755-HF serves in the applications of telecommunications, instrumentation, and computer, and has become the most popular choice for high frequency devices due to its reliable performance.

The ACZRA4755-HF is a small package which utilizes a 20-lead, surface mount package and is capable of supporting a frequency range up to 100GHz. This makes the ACZRA4755-HF the ideal choice for many designs that require a high frequency clamping diode. Its design also allows it to operate at higher voltages and temperatures than traditional Zener diodes. This capability makes the ACZRA4755-HF a great choice for applications such as voltage regulators, high frequency clamps, and voltage reference sources.

The ACZRA4755-HF belongs to the family of n-type semiconductor devices, meaning it has a positively charged semiconductor substrate. This type of device has the unique ability to create a high electrical resistance when an electronic current is applied, which is why it is an excellent choice for high frequency devices. The ACZRA4755-HF has a reverse leakage current of only 1 nanoampere (nA) and a reverse breakdown voltage (VBR) of 8.5 volts (V). This allows it to be utilized as a good Zener diode.

The ACZRA4755-HF is equipped with a power dissipation rating of 300 mW, a reverse current rating of 25 mA and a forward current rating of 100 mA. It also has a capacitance value of 3.2 -3.6 pF which is much lower than any commonly available Zener diode. This means that this diode has a much higher frequency range than any other device.

The ACZRA4755-HF operates by allowing a variable current to flow across the diode junction. When the voltage reaches the breakdown voltage, current will suddenly flow through the diode, creating an avalanching effect and providing a desired voltage drop. This action is what makes the ACZRA4755-HF useful for a variety of applications.

In summary, the ACZRA4755-HF is a high frequency Zener diode designed to serve in telecommunications, instrumentation, and computer applications. Its small package and frequency range of up to 100GHz make it an ideal choice for many designs. It’s reverse leakage current of 1 nanoampere and reverse breakdown voltage of 8.5 volts make it an excellent Zener diode. It also has a power dissipation rating of 300 mW, a reverse current rating of 25 mA and a forward current rating of 100 mA, making it suitable for use in a variety of applications. Lastly, the ACZRA4755-HF operates by allowing a specific current to flow across the diode junction, creating a desired voltage drop when the voltage reaches the breakdown voltage.
