That 2500Vrms covers basic insulation for industrial bus nodes, motor drives, and medical patient-coupled circuits where the I²C bus must cross a galvanic barrier without corrupting the clock or data. Common-mode transient immunity of 35kV/µs minimum means the isolator holds the data path clean when a motor drive or inverter switches — the output won't glitch from the fast voltage slew across the isolation barrier. The 3/3 input configuration per side maps directly to bidirectional SDA and SCL lines plus a separate output-enable pin for bus arbitration. Supply voltage spans 3V to 5.5V, so it mates directly with both 3.3V and 5V I²C buses without a level translator on the isolator side. The -40°C to 125°C operating range covers the full industrial temperature envelope — no derating needed for hot enclosures or cold starts. ## Package, mounting, and compliance Housed in a 16-SOIC narrow-body (0.154-inch width, 3.90mm body), the SI8605AB-B-IS1 mounts on standard surface-mount pads. The supplier device package is 16-SOIC — same footprint as a generic SOIC-16, so no special land pattern needed. Shipped in tube packaging (the standard for low-volume production and prototyping). ROHS3 compliant per, with no isolated power rail required — the device draws its supply from the bus-side VDD. ## Active lifecycle and sourcing For BOM placement, the SI8605AB-B-IS1 is an authorized production part. Sourced to order against your quantity; availability and current pricing confirmed at RFQ. No functional second-source cross-reference is published by the manufacturer — the Skyworks SI8605 series is a proprietary design.","metaTitle":"Skyworks SI8605AB-B-IS1 I²C Digital Isolator, 2500Vrms","metaDescription":"Skyworks SI8605AB-B-IS1 I²C digital isolator, 4-channel, 2500Vrms isolation, 35kV/µs CMTI, -40°C to 125°C.

The SI8605AC-B-IS1 is the 3750Vrms variant; the SI8605AB-B-IS1 is the 2500Vrms version. All other parametrics — channel count, supply range, temperature range, CMTI — are identical. The only difference is the isolation voltage rating, so a board laid out for the AC variant accepts the AB part directly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/skyworks/SI8605AB-B-IS1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/skyworks/SI8605AB-B-IS1 when reusing this data.
