The SI8660BB-B-IS1: ROHS3 compliance is confirmed, covering the full RoHS exemption set under EU Directive 2011/65/EU.
Parametric fit — isolation, speed, and timing margins
Rated for 2500 Vrms isolation with capacitive coupling technology — this is the basic isolation tier for general-purpose galvanic separation in industrial control, instrumentation, and isolated data interfaces. The 35 kV/µs common-mode transient immunity (CMTI) ensures the output stays clean during fast voltage transients across the isolation barrier, such as those from motor-drive switching or relay coil kickback. At 150 Mbps data rate with a 13 ns max propagation delay (tpLH / tpHL) and 4.5 ns max pulse-width distortion, the part handles high-speed serial protocols like SPI, RS-485, and CAN FD without introducing significant skew. The 2.5 ns typical rise/fall time means the signal edges are fast enough for 150 Mbps but not so aggressive that they create excessive EMI on a poorly terminated trace. Six unidirectional channels configured as all inputs on side 1 (6/0) — this is a pure transmitter-side isolator. It fits designs where six digital signals from a single source (e.g., an MCU or FPGA) need isolation to a receiver domain, with no reverse-direction channels.
Temperature grade and package — board integration notes
Operating temperature from -40°C to 125°C covers industrial and extended-industrial environments — motor drives, power supplies, and outdoor telecom equipment that see ambient heat near 105°C still have 20°C of margin. Supplied in tube packaging — the standard anti-static tube for 16-SOIC.
