The IRKJ71/12A device is a diode array, which comprises of two individual ultra-fast high voltage rectifiers. Quite similar to its single rectifier counterparts, the diodes in the IRKJ71/12A device feature a very high forward surge current capability, whilst the components are capable of ensuring low reverse voltage leakage. This makes the device suitable for a whole range of applications, ranging from low voltage full-wave rectification tasks to more demanding rectification needs. The device’s high voltage rectifier components are built in the form of a Planar Passivated Chipset, allowing for stable operation when the components come into contact with an electromagnetic environment. This also allows for the device to maintain a low forward voltage drop, meaning that it can be used in situations with low power products or limited power requirements. The application field for the IRKJ71/12A device is specifically related to applications that either require a fast and accurate full-wave rectification of AC signals or special protection applications related to electromagnetic compatibility. The device is suitable for a wide range of applications, such as rectifying and protecting electronic circuits, rectifying spot welder controllers, rectifying motor control systems, rectifying automotive brakes and rectifying and protecting low power products, such as communication systems. The device also holds a wide range of features that can be adjusted on a per-circuit basis to fit the needs of each application. The IRKJ71/12A device features an UltraFET-passivated chipsets and contact surfaces. This ensures that the contact surfaces have undergone a treatment process that guarantees low forward voltage and low contact resistance. This helps improve the efficiency of the rectifier and offers a compact form factor. The working principle behind the IRKJ71/12A device can be divided into three main stages, namely switching, rectifying and protection. The switching stage is responsible for controlling the current through the rectifier and preventing any direct contact between the rectifier and ground. The rectifying stage however, is responsible for generating a steady DC output from the input AC. The last stage of protection prevents any interference from the electromagnetic environment and ensures that the AC signal is correctly rectified without suffering any damage. The IRKJ71/12A device is therefore a compact and efficient diode array that offers a wide variety of features and characteristics to its users. With its specialised surge current design, low forward voltage as well as a thermal protection circuit, the device is capable of providing reliable and high performance full-wave rectification to a wide range of applications.
