High Speed Dual-Channel, Bi-Directional Ceramic Digital Isolator


  • Digital Isolator Matching Insulation Reliability of Optocouplers (DTI ≥ 0.5 mm)
  • High Speed, No Insulation Material Wear Over Time and No Degradation
  • 8 mm Clearance and Creepage, SO16 Wide Body Package
  • Safety and Regulatory Approvals, AEC−Q100 Qualified

The NCID9211 is part of a family of galvanically digital isolators that use ON Semiconductor's patented off-chip capacitor isolation technology. These isolators support digital communication between systems without conducting ground loops or hazardous voltages.

Their capactive ceramic substrate construction offers ~25 times the thickness of thin film on-chip capacitors and coreless transformers, resulting in electrical performance benefits traditionally offered by optocouplers but exceeding optocouplers in speed, common mode transient immunity as well as temperature and lifetime performance.
