Introduction

Diodes, rectifiers and arrays are common devices found in a wide range of electronic systems. These components are used to control the flow of electrical current, regulate voltage and create specific electrical characteristics. The WNS40H100CBJ is an example of such a device. It is a four-pin surface mounted rectifier bridge array that is designed to provide protection against transient excess current in automotive systems. In this article, the application and working principle of the WNS40H100CBJ will be examined to understand its capabilities and how it fits in with other diodes and rectifiers.

Application of WNS40H100CBJ

The WNS40H100CBJ is ideal for providing protection against motor stalls or short-circuits in automotive systems. It is particularly useful in applications that can’t rely on mechanical protection circuits such as motor control circuits and motor drive circuits. It can be used to protect ground faults as well, which is important in electric vehicle systems. The device is a single dual rectifier array that can handle current up to 4A with a forward voltage drop of 1V. It has an operating temperature range between -40°C to 155°C, making it suitable for a wide range of automotive applications. Additionally, it is designed to meet the requirements of ISO 7637-2, ensuring it is capable of withstanding electrical transients and surges as required for mobile applications. The WNS40H100CBJ is also designed for convenience, thanks to its four-pin configuration that can be surface mounted on the board. It also comes in a small SMP package that is ideal for applications with limited space.

Working Principle

The WNS40H100CBJ is a dual rectifier array, meaning it consists of two low-voltage diodes connected in series. This allows the device to convert AC into DC current and provides protection against reverse voltage. The two diodes are used to rectify voltage. In other words, they convert alternating current (AC) into direct current (DC). As the current flows through the diodes, electrical energy is transferred from the anode of one diode to the anode of the other. This causes a forward voltage drop, causing the current to flow in the correct direction. The device also provides protection from over-voltage and over-current by limiting the amount of current that can flow through the diode array. This gives the device its robustness and makes it suitable for automotive applications.

Conclusion

The WNS40H100CBJ is a robust and reliable device used in automotive systems. It is a dual rectifier array that provides both current limiting and conversion of AC to DC. This makes it useful for preventing motor stalls or short circuits and protecting against excessive currents, making it ideal for use in electric vehicles. The package is also designed for convenience and fits easily into board designs.
