AZ23B43-HE3-18 Application Field and Working PrincipleDiodes are electronics components that act as a switch and are commonly used to provide a path between two points in a circuit and protect other components by blocking current during reverse conduction. Common types of diodes include semiconductor diodes, including carbon-based and silicon-based, as well as Zener diodes, which are used for voltage regulation. Diodes can also come as an array of components, such as the AZ23B43-HE3-18 from IXYS Corporation. IXYS CorporationIXYS Corporation is a semiconductor company that manufactures a variety of power semiconductor components and modules. Their components range from rectifiers and diodes to more advanced products such as resonant converters and adjustable frequency electronic components. The IXYS Corporation also produces active and passive components for high-voltage systems, such as the AZ23B43-HE3-18.AZ23B43-HE3-18The AZ23B43-HE3-18 diode array is a six-terminal, 5.5 Volt Zener diode array designed for use in high-voltage applications. The device is a multi-element diode, meaning that it contains several diodes of varying configurations in one package. The array has three series elements and three parallel elements, which allow it to provide a variety of different protective and regulating functions. The AZ23B43-HE3-18 is made with a high-reliability planar technology and is housed in a PPAK encapsulated package.Application FieldThe AZ23B43-HE3-18 is well-suited for use in high-voltage and high-current circuits, such as those in seismic, communications, and industrial systems. It\'s capable of providing protection against over-voltage and reverse current flow and can also be used to regulate current and provide a stable voltage output.The diode array is particularly useful in pulsing and switching applications where it can establish a controlled current flow and prevent arcing between circuits.Working PrincipleThe AZ23B43-HE3-18 involves several components working in unison in order to protect and regulate current flow in a circuit. The array contains three series and three parallel elements, all of which are made of a combination of resistors, capacitors, and Zener diodes. When a voltage higher than the desired value is applied to the diode array, the Zener diode conducts current and reduces the voltage to its nominal value, preventing device overload and protecting vulnerable components. The AZ23B43-HE3-18 is also able to reverse current flow, as it contains a pair of diodes connected in anti-parallel (opposite to each other). This allows current to flow in both directions without creating damaging arcing or damaging components. The parallel elements of the array further protect the circuit by absorbing excess voltage and current and dissipating it safely.In conclusion, the AZ23B43-HE3-18 diode array is a useful device for high-voltage and high-current applications. It’s capable of protecting components from over-voltage and providing a controlled current flow. This diode array is ideal for use in pulsing and switching applications and is available in a reliable and compact package.
