Diodes in general, and more specifically rectifier arrays, are invaluable components to a wide variety of electronic and electrical systems. The VS-20CTH03-1PBF diode rectifier array is no exception. It is a four-way monolithic chip with built in protection against thermal and overvoltage stresses. This article will describe the application field as well as the working principle of the VS-20CTH03-1PBF.

Application Field

The VS-20CTH03-1PBF is an ideal choice for a wide range of applications such as AC/DC primary ripple filtering, circuit protection and input rectification, LED driving, battery charging, spark suppression and motor control. Because of its low forward voltage drop, the device offers excellent energy-saving performance and diode protection. It has a wide degree of flexibility which makes it suitable for automation, switching, and control systems.

The rectifier array is also ideal for applications in industrial, automotive, and medical industries, due to its low leakage current and very low capacitance. Its anti-parallel Schottky diodes also provide reliable circuit protection. Its two-line addressability allows for easy current and voltage sharing, providing a solution for high current output applications.

The VS-20CTH03-1PBF is a surface mount component and is designed to fit into a 6mm x 6mm space. This means it can be fitted into various spaces, such as tight corners, gaps or on narrow PCBs.

Working Principle

The working principle of the VS-20CTH03-1PBF is relatively simple. It is made up of a series of four Schottky diodes connected in parallel. The structure holds the diode arrays at a constant voltage. When connected to a positive voltage source, the diodes are reverse biased and no current is allowed to flow through them. However when connected to a negative voltage source, the diodes are forward biased and current is allowed to flow through them.

The anti-parallel Schottky diodes are connected in two reverse-parallel configurations, to provide protection from overvoltage and overcurrent surges. The two configurations share the current equally, which helps to evenly distribute the current and helps prevent damage to the diode array. The two-line addressability of the VS-20CTH03-1PBF allows for simultaneous control of the current and voltage on each line.

The low forward voltage of the VS-20CTH03-1PBF makes it an ideal choice for applications where high current and low power consumption is desired. It provides protection from overvoltage and overcurrent conditions and is extremely reliable in switching and control applications.

In summary, the VS-20CTH03-1PBF is a very versatile diode rectifier array with a wide range of applications. It has excellent energy-saving performance and diode protection, and is suitable for industrial, automotive, and medical applications. The two-line addressability provides flexibility and reliable circuit protection, and its low forward voltage allows for high current output.
