It provides 2500Vrms of galvanic isolation across four unidirectional channels in a 3/1 input-side-1/input-side-2 configuration, using magnetic coupling technology. Propagation delay is 100ns max (both tpLH and tpHL), and common-mode transient immunity is rated at 25kV/µs minimum. The 2500Vrms isolation rating is the working voltage the part can withstand between input and output sides for 1 minute per the basic insulation test. In an automotive 12V/24V system with occasional load-dump transients, this provides a comfortable margin for protecting the low-voltage controller from the high-side or motor-drive side. The 25kV/µs common-mode transient immunity (CMTI) means the isolator rejects fast voltage spikes — such as those from a switching MOSFET or an ignition coil — without corrupting the data on the output. For a CAN or SPI link crossing a noisy power boundary, this CMTI figure keeps the bus from seeing false edges. ## Automotive temperature range and package fit The wide-body 16-SOIC (7.50mm body width) provides 8 mm creepage distance between input and output pins, which is the standard for 2500Vrms reinforced isolation in a surface-mount package. The package is MSL-rated per the iCoupler family; check the MSL level on the reel label before reflow — if it's MSL 3, bake the parts if the moisture barrier bag has been open longer than the floor life.","metaTitle":"ADUM1401WSRWZ-RL Automotive Digital Isolator, 2500Vrms","metaDescription":"ADI ADUM1401WSRWZ-RL automotive-grade digital isolator: 2500Vrms isolation, 1Mbps, 4 unidirectional channels, -40°C to 125°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","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":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"2500Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"3/1","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"40ns","Propagation Delay tpLH / tpHL (Max)":"100ns, 100ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.41","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.41000","currency":"USD"},{"qty":10,"price":"$7.60000","currency":"USD"},{"qty":25,"price":"$7.24680","currency":"USD"},{"qty":100,"price":"$6.29230","currency":"USD"},{"qty":250,"price":"$6.00952","currency":"USD"},{"qty":500,"price":"$5.47924","currency":"USD"},{"qty":1000,"price":"$4.77225","currency":"USD"},{"qty":2000,"price":"$4.59550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1ede0b49820924dd19648c8b0dbeca5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM1401WSRWZ-RL have automotive qualification?","answer":"Yes, the part is listed with an Automotive grade, which corresponds to AEC-Q100 qualification."},{"question":"What is the difference between ADUM1401WSRWZ and ADUM1401WSRWZ-RL?","answer":"The -RL suffix designates Tape & Reel packaging.
