The 25 kV/µs common-mode transient immunity handles the switching noise from motor drives and inverter stages without false triggering. ## Automotive grade and 125°C junction — under-hood ready This matters for engine bay, transmission, and battery-management isolation where the ambient can exceed 105°C — the ADUM1300CRWZ, by contrast, stops at 105°C. The 3000 Vrms isolation rating meets the reinforced insulation requirement for traction inverter and onboard charger signal paths. ## Package and layout — 8-SOIC with no isolated power The ADUM1285WCRZ comes in an 8-SOIC (3.90 mm width) package, surface-mount only. It does not include an integrated isolated DC-DC converter — the 'No Isolated Power' flag means the secondary side needs its own supply rail. For a two-channel unidirectional isolator, the 2/0 input-side/side-2 count means both channels drive from side 1 to side 2; the ADUM1281WARZ offers a 1/1 bidirectional split if you need a return channel. The 8-SOIC footprint is standard, and the 3000 Vrms isolation is tested per the datasheet's 1-minute hipot routine.","metaTitle":"ADUM1285WCRZ Automotive Digital Isolator, 100Mbps, 3000Vrms","metaDescription":"ADUM1285WCRZ automotive-grade digital isolator: 100Mbps data rate, 3000Vrms isolation, 25kV/µs CMTI, -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","Grade":"Automotive","Package":"Tube","Data Rate":"100Mbps","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)":"2ns","Propagation Delay tpLH / tpHL (Max)":"24ns, 24ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.62","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.62000","currency":"USD"},{"qty":10,"price":"$8.68600","currency":"USD"},{"qty":25,"price":"$8.28200","currency":"USD"},{"qty":100,"price":"$7.19120","currency":"USD"},{"qty":250,"price":"$6.86800","currency":"USD"},{"qty":500,"price":"$6.26200","currency":"USD"},{"qty":1000,"price":"$5.45400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8e75547927d6f41e80c5c7dd03fbac65.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is ADUM1285WCRZ AEC-Q100 qualified for automotive use?","answer":"Yes, the 'W' in the order code indicates automotive grade (AEC-Q100 qualified)."},{"question":"What is an equivalent replacement for ADUM1285WCRZ?","answer":"The ADUM1200WTRZ is a two-channel unidirectional isolator but runs at 10 Mbps with 2500 Vrms isolation — lower speed and isolation.
