That bandwidth handles SPI at full speed, UART at any baud rate, and parallel control signals without timing margin trouble. The 13 ns max propagation delay (tpLH / tpHL) and 4.5 ns pulse-width distortion keep the data eye open across the isolation barrier. ## 35 kV/µs common-mode transient immunity — why it matters for motor drives and inverters A minimum 35 kV/µs common-mode transient immunity (CMTI) means the isolator holds its output state when a fast voltage transient slams across the barrier. In a motor-drive or inverter circuit, the IGBT switching edges generate common-mode dv/dt well above 10 kV/µs — this part has headroom to avoid data corruption or latch-up. ## Drop-in compatibility with the SI8660BD-B-IS The SI8660BD-B-IS shares the same 16-SOIC wide-body package, 150 Mbps data rate, 6/0 channel configuration, 5000 Vrms isolation, and 35 kV/µs CMTI. The two parts are functionally identical — the suffix difference (ED vs BD) reflects a manufacturing or test-code variant, not a parametric change. A board laid out for one accepts the other without a layout spin.","metaTitle":"Skyworks SI8660ED-B-IS Digital Isolator, 6Ch, 150Mbps","metaDescription":"Skyworks SI8660ED-B-IS general-purpose digital isolator: 6 unidirectional channels, 150 Mbps data rate, 5000 Vrms isolation, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Package":"Tube","Data Rate":"150Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"6/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.5ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"35kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.26","stockQuantity":16,"priceTiers":[{"qty":1,"price":"$6.26000","currency":"USD"},{"qty":10,"price":"$5.62500","currency":"USD"},{"qty":25,"price":"$5.31760","currency":"USD"},{"qty":100,"price":"$4.60860","currency":"USD"},{"qty":250,"price":"$4.37228","currency":"USD"},{"qty":500,"price":"$3.92324","currency":"USD"},{"qty":1000,"price":"$3.30876","currency":"USD"},{"qty":2500,"price":"$3.14332","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d0fd34ad18bd716c3bfaa7fe80e62960.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will SI8660ED-B-IS drop into a board laid out for SI8660BD-B-IS without rewiring?","answer":"Yes.
