It ships in an 8-SOIC narrow-body package (3.90 mm width) in tube format. The input side runs from the same supply range, simplifying a single-rail design. ## 15 Mbps data rate with 35 kV/µs common-mode transient immunity This timing symmetry matters for SPI or UART isolation where the clock-to-data skew budget is tight. Common-mode transient immunity is rated at a minimum 35 kV/µs. At this level, the isolator holds its output state through a fast ground-potential step between the two sides — a typical condition when a motor drive or relay bank switches and the return current jumps across the isolation barrier. Rise and fall times are 15 ns and 5 ns typical respectively, so the output edges are fast enough for 15 Mbps signalling without excessive ringing into a 15 pF load. ## Active lifecycle, ROHS3, industrial temperature range The 8-SOIC package (supplier device package 8-SOIC) is a standard footprint with no hidden thermal pad requirements.","metaTitle":"Skyworks SI8712BC-B-IS Digital Isolator, 3750Vrms, 15Mbps","metaDescription":"Skyworks SI8712BC-B-IS digital isolator, 1-channel unidirectional, 3750Vrms isolation, 15Mbps data rate, 35kV/µs CMTI.

The only difference is the shipping format: the SI8712BC-B-IS comes in a tube, while the SI8712BC-B-ISR ships on tape and reel. No board-level rework or re-spin is needed to swap between them."},{"question":"Will SI8712BC-B-IS drop into a board laid out for SI8710BD-B-IS?","answer":"No, not without a layout change. The SI8710BD-B-IS is a 5000 Vrms-rated part in the same 8-SOIC footprint, but its isolation rating requires a wider creepage clearance on the PCB. The SI8712BC-B-IS is 3750 Vrms and may not meet the same safety spacing. Check the clearance between primary and secondary copper under the package before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/skyworks/SI8712BC-B-IS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/skyworks/SI8712BC-B-IS when reusing this data.
