Si86xx Digital Isolators Family

Silicon Labs’ digital isolators offer support for up to 5 kV reinforced rating, and unidirectional and bidirectional isolation

Image of Silicon Labs Si86xx Digital Isolators FamilyThe Silicon Labs Si86xx family is the industry’s highest performing, widest channel count series of unidirectional and bidirectional isolators supporting up to reinforced 5 kVRMS isolation ratings. Based on Silicon Labs’ patented CMOS isolation technology, Si86xx isolators enable robust operation in harsh industrial applications.

Features
  • Up to 5000 VRMS isolation
  • UL, CSA, and VDE certification
  • 60-year life at rated working voltage
  • High electromagnetic immunity
  • Independent, bidirectional SDA and SCL isolation channels
    • Open drain outputs with 35 mA sink current
    • Supports I²C clocks up to 1.7 MHz
    • Unidirectional isolation channels support additional system signals (Si8605, Si8606)
  • Supply voltage 2.5 V to 5.5 V
  • -40°C to +125°C temperature range
  • Common mode transient immunity 50 kV/μs
  • AEC-Q100 qualification
  • RoHS compliant packages
    • SOIC-8 narrow body
    • SOIC-16 wide body
    • SOIC-16 narrow body
Applications
  • Industrial
    • IEC 60950 (transitioning to IEC 62368) requires 8 mm for higher working voltages
    • IS2 also extends qualification to IEC 62368
  • Medical Applications
    • IEC 60601 requires 8 mm for 250 VRMS for 2 MOPP (two means of patient protection, most stringent requirement) or to use conformal coating
    • IS2 extends use from 125 VRMS to 250 VRMS with no coating
