It provides 3000 Vrms galvanic isolation between two voltage domains — enough for reinforced insulation in industrial power supplies, motor drives, and isolated sensor interfaces. At 1 Mbps data rate with 50 ns max propagation delay, it handles isolated SPI clock lines, UART TX/RX, and general-purpose logic signals comfortably. The 25 kV/µs common-mode transient immunity means it holds data integrity even when the isolated side sees fast voltage swings from a switching power stage or an inverter. ## 25 kV/µs CMTI — the real gatekeeper for motor-drive and inverter use Common-mode transient immunity of 25 kV/µs (minimum) is the spec that separates a digital isolator that works in a noisy environment from one that glitches. In a motor-drive or solar-inverter application, the switching node can slew at tens of kV/µs. If the isolator cannot reject that common-mode step, the output sees a false edge. The ADUM1286ARZ-RL7's 25 kV/µs rating covers the majority of industrial drive and power-supply designs up to medium voltage. ## 1 Mbps data rate — what it covers and what it doesn't 1 Mbps is the sweet spot for isolated control signals — SPI at a few MHz, UART at 115.2 kbaud or 1 Mbaud, general-purpose GPIO isolation, and isolated I2C (with an external pull-up). It will not support full-speed USB (12 Mbps), 100 Mbps Ethernet, or high-speed serial links. For those, you need a 10 Mbps or 150 Mbps rated part like the ADUM1210BRZ-RL7. ROHS3 compliant. ## Package and temperature grade Housed in an 8-pin SOIC (body width 3.90 mm), surface-mount.","metaTitle":"ADUM1286ARZ-RL7 Digital Isolator, 3000Vrms, 1Mbps, SOIC-8","metaDescription":"ADUM1286ARZ-RL7 iCoupler dual-channel digital isolator, 3000Vrms isolation, 1Mbps data rate, 25kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"1Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"2","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"1/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"8-SOIC","Pulse Width Distortion (Max)":"10ns","Propagation Delay tpLH / tpHL (Max)":"50ns, 50ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.32000","currency":"USD"},{"qty":10,"price":"$2.98100","currency":"USD"},{"qty":25,"price":"$2.81800","currency":"USD"},{"qty":100,"price":"$2.44220","currency":"USD"},{"qty":250,"price":"$2.31696","currency":"USD"},{"qty":500,"price":"$2.07898","currency":"USD"},{"qty":1000,"price":"$1.75336","currency":"USD"},{"qty":2000,"price":"$1.66569","currency":"USD"},{"qty":5000,"price":"$1.60307","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8e75547927d6f41e80c5c7dd03fbac65.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM1286ARZ-RL7 obsolete or end-of-life?","answer":"It is a current-production part suitable for new designs."},{"question":"Does ADUM1286ARZ work with 5V supply and 3.3V on the other side?","answer":"Yes.
