It provides 3750 Vrms isolation between Side 1 and Side 2, with a 3/3 input split — three bidirectional channels for the SDA/SCL lines plus a unidirectional side channel for a clock or data line. Capacitive coupling means lower power and faster edge rates than optocouplers — the 35 kV/µs common-mode transient immunity (CMTI) keeps data intact when a motor drive or inverter switches a few hundred volts in microseconds. ## Industrial temperature and board-fit The 0.154-inch body height clears most potting compounds and conformal coatings.","metaTitle":"Skyworks SI8605AC-B-IS1 I²C Digital Isolator, 3750 Vrms","metaDescription":"Skyworks SI8605AC-B-IS1 I²C digital isolator: 3750 Vrms, 4 channels, capacitive coupling, -40 to 125°C, 16-SOIC.

The only difference is isolation voltage: 5000 Vrms on the AD variant versus 3750 Vrms on the AC. If your board already has the clearance and creepage for 5000 Vrms, the SI8605AC-B-IS1 fits the same footprint and BOM position."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/skyworks/SI8605AC-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/SI8605AC-B-IS1 when reusing this data.
