Silicon Labs Si86xx Six-Channel Digital IsolatorsSilicon Labs Si86xx digital isolators are the industry's first six-channel 5kV digital isolators. These Silicon Labs six-channel digital isolators offer the highest channel count, performance, and data rate for demanding applications with isolation ratings up to 5kV. Si86xx 3.5kV and 5kV digital isolators replace optocouplers in target applications requiring robust operation and high levels of insulation protection, such as industrial automation and drives, motor control, and medical systems. With its 5kV rating, the Si86xx family offers an ideal isolation solution for isolated ac-dc and dc-dc power supplies, as well as solar panel microinverters, data communications systems, and hybrid electric vehicles (HEVs).
Silicon Labs Si86xx isolators deliver the industry's fastest data rate (150 Mbps) across the widest temperature range (-40 to 125ºC), as well as ultra-low power operation of less than 1.6 mA per channel at 1 Mbps for energy-efficient system design. The robust architecture of the Si86xx family ensures that signal integrity is maintained even while operating at high data rates and at high temperatures in harsh environments.
