Rated for 10 Mbps data rate with a typical rise/fall time of 2.5 ns, it fits isolated SPI, UART, or general-purpose signal paths where the isolation voltage requirement is under 1 kV and the direction is fixed. The 35 kV/µs minimum common-mode transient immunity means it holds its state through fast-switching inverter or motor-drive noise — a spec that matters more than the isolation voltage in noisy industrial backplanes. ## Timing margins and temperature range — what the propagation delay buys you Maximum propagation delay is 65 ns in either direction, with pulse-width distortion capped at 30 ns — the timing skew between channels is bounded, so a three-line parallel bus stays within a single clock cycle at 10 Mbps. ## Package and supply-chain reality — 16-QSOP footprint, active lifecycle Housed in a 16-QSOP (3.90 mm width, 0.154\" pitch), the SI8035AA-B-IU is a surface-mount part supplied in tube packaging — the narrow body suits dense board layouts, but the 0.025\" lead pitch demands a controlled solder profile. Skyworks lists this as an active product with RoHS3 compliance (no exemptions). The date-code and marking should trace cleanly through the authorized channel — any lot with mismatched laser etch or inconsistent tube orientation flags a counterfeit risk. No stock-holding claim — confirm the BOM quantity and the required date-code window before committing.","metaTitle":"SI8035AA-B-IU Skyworks Digital Isolator, 3Ch, 10Mbps","metaDescription":"Skyworks SI8035AA-B-IU digital isolator: 3 unidirectional channels, 10Mbps data rate, 1000Vrms isolation, -40°C to 125°C.
