Diodes - Zener - Arrays

The AZ23B4V7-HE3-18 is a type of diode array, consisting of multiple Zener diodes which are integrated into a single package.

The main purpose of this device is to provide protection from transient voltage levels which may be encountered in electronic systems. Such transients could include drops in current, spikes in voltage, or other over-voltage and reverse-voltage events. The AZ23B4V7-HE3-18 uses Zener diodes to handle these transients and protect the system from damage.

Application Fields

The AZ23B4V7-HE3-18 is commonly used in a variety of applications, including automotive electronics, industrial control systems, and other areas. It is also used as a protective device in power supplies and other power systems to protect against over-voltage and reverse-voltage conditions.

For automotive applications, the device provides power supply protection from a variety of possible electrical disturbances such as spikes, transient voltage drops, or over-voltage events. It also helps reduce power consumption by regulating power supply current levels. In industrial control systems, the AZ23B4V7-HE3-18 can be used as a protective device to protect the system from over-voltage or short-circuit conditions.

Working Principle

The working principle of the AZ23B4V7-HE3-18 is based on its Zener diode array. It is a type of diode array that consists of several Zener diodes which are connected in parallel. The diodes act as voltage-controlled switches, meaning that when the voltage applied to the device reaches its breakdown threshold, the diodes will become conductive and allow current to flow.

The AZ23B4V7-HE3-18 is designed so that the Zener breakdown voltages of the diodes are well matched, meaning that the device can be used to effectively clamp any transient voltages that may appear. This means that the device can protect against over-voltage, reverse-voltage, and other dangerous voltage conditions.

In addition, the AZ23B4V7-HE3-18 has an additional protection function, known as reverse blocking. This means that when the device is used in reverse bias, it will block any current from flowing through the device.

Conclusion

In conclusion, the AZ23B4V7-HE3-18 is a type of diode array which consists of multiple Zener diodes integrated into a single package. It is commonly used in automotive electronics and industrial control systems to provide protection against transient voltage events. It works by using the Zener diodes to clamp the voltages, and also provides reverse blocking to protect against reverse-biased current.
