The AZ23B4V7-E3-18 diode array is a type of diode that is used for voltage regulation and electrical noise attentuation applications. It operates in a manner much like conventional Zener diodes and is designed to meet a single voltage point, providing a predictable breakdown as the current level increases. The AZ23B4V7-E3-18 diode array is a package form that contains 18 individual diode chips in one package, instead of having multiple discrete diodes. This array comes housed in an easy-to-use, low-profile, surface-mount package, which saves both board space and manufacturing costs.

The AZ23B4V7-E3-18 array is capable of operating at voltages ranging from 10 volts to 50 volts and can handle peak transient currents of up to 3 amps. It is most commonly used in high-current applications, as it provides greater protection than other diode types. The operating temperature range of this diode array is -55°C to 125°C.

The working principle of the AZ23B4V7-E3-18 diode array is based on the Zener voltage effect, which states that the junction breakdown voltage of a Zener diode is predictable and reproducible. In a Zener diode, when the voltage across the junction exceeds the Zener voltage, the junction breaks down, allowing current to pass through. The ability of the diode to breakdown at a specific voltage level depends on the doping profile and the doping concentration of the diode, which are both predetermined. This allows the diode array to act as a voltage regulator, as the voltage across the diode array is limited to a predetermined breakdown voltage.

The AZ23B4V7-E3-18 diode array is most commonly used as an EMI filter. The array features EMI protection from 10MHz to 1000MHz, providing adequate noise attenuation for most applications. It is also used in over-voltage protection, as the individual diodes can be connected in series for higher breakdown voltages. It can also be used as a voltage reference, as the diode array is designed to have a predictable breakdown voltage.

The AZ23B4V7-E3-18 diode array is a versatile and reliable component that is used in a wide range of applications. Its EMI protection and over-voltage protection capabilities make it a great choice for high-current applications, while its compact size and wide voltage range makes it a great solution for space-conscious designs. With its predictable breakdown voltage and wide temperature range, the AZ23B4V7-E3-18 diode array can be used in a variety of voltage regulation, noise attenuation and over-voltage protection applications.
