The 3000Vrms isolation rating is the headline safety spec: it provides reinforced isolation for applications that need to separate high-voltage and low-voltage domains — think motor-drive control signals, industrial PLC I/O, or isolated power-supply feedback paths. The 1Mbps data rate is enough for most serial interfaces (UART, SPI at moderate clock speeds) but check your bus timing budget: propagation delay is 50ns max each way, and pulse-width distortion is held to 10ns max. ## Common-mode transient immunity matters here The 25kV/µs minimum CMTI is the spec that separates this part from older optocoupler-based isolators. In a motor drive or inverter, the switching node can slam the isolation barrier with a high dV/dt — if the isolator's CMTI is too low, data gets corrupted or the output glitches. 25kV/µs is a solid figure for most industrial drives; it means the part holds its state through fast common-mode edges without needing a snubber or extra filtering on the digital side. ## Package and footprint Housed in an 8-pin SOIC with 3.90mm body width (the standard 150-mil footprint). Surface-mount only, no through-hole option. No exposed pad — standard SOIC-8 thermal management applies.","metaTitle":"ADUM1280ARZ-RL7 iCoupler Digital Isolator, 3000Vrms, 1Mbps","metaDescription":"ADUM1280ARZ-RL7 iCoupler digital isolator: 3000Vrms isolation, 1Mbps data rate, 2 unidirectional channels, -40°C to 125°C, 8-SOIC.","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":"2/0","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":"$3.34","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.34000","currency":"USD"},{"qty":10,"price":"$2.99900","currency":"USD"},{"qty":25,"price":"$2.83520","currency":"USD"},{"qty":100,"price":"$2.45700","currency":"USD"},{"qty":250,"price":"$2.33100","currency":"USD"},{"qty":500,"price":"$2.09160","currency":"USD"},{"qty":1000,"price":"$1.89000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8e75547927d6f41e80c5c7dd03fbac65.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of ADUM1280ARZ?","answer":"The maximum data rate is 1Mbps.
