Digital isolators

Highest working voltage, lowest emissions, lowest power and highest efficiency

parametric-filterView all products
Explore our portfolio of basic and reinforced digital isolators based on a proprietary silicon dioxide (SiO2) insulation barrier for industry-leading performance. These high-voltage, high-speed, low-power, small-size, integrated-power, radiation-tolerant, and ATEX/IECEx-certified isolators are designed to meet a range of design challenges. Whether you need isolation in a very cost-sensitive application, an industrial factory application that must endure harsh temperatures and system noise, or automotive HEV/EV application where size and weight reduction is critical, or even in NewSpace applications, our high-performance digital isolators can help.
