SI8631BD-B-IS +BOM

The SI8631BD-B-IS is a digital isolator with three channels, providing 5 kV of isolation in both forward and reverse directions

SI8631BD-B-IS Descrizione generale

The SI8631BD-B-IS digital isolator by Silicon Labs is a cutting-edge product designed to meet the stringent requirements of modern industrial automation, medical devices, and power supplies. Featuring two isolated channels, it ensures exceptional signal isolation, safeguarding against voltage spikes and noise. With a high data rate of up to 150 Mbps, it enables rapid and reliable communication between isolated circuit sections. Additionally, its supply voltage range of 2.5 to 5.5 volts and small form factor make it versatile and suitable for space-constrained and battery-powered applications. Enhanced by reinforced insulation that meets international safety standards, the SI8631BD-B-IS offers reliable isolation between input and output circuits, significantly improving system reliability and performance
