Si86xx Digital Isolators Family

The Silicon Labs Si86xx family is one of the 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
