The output supply range is 6.5 V to 24 V, which directly biases the gate-drive stage — no separate regulator needed between the 12 V or 24 V vehicle battery rail and the isolator's VDDA/VDDB pins. ## Approvals and compliance Carries CQC, CSA, UR, and VDE approval marks, so the same BOM position qualifies for UL-recognized equipment in North America, CSA-certified machinery in Canada, and VDE-marked installations in Europe.","metaTitle":"Skyworks SI8234AB-D-IM1 Digital Isolator, 4A Peak, AEC-Q100","metaDescription":"Skyworks SI8234AB-D-IM1 dual-channel gate driver isolator, 4A peak output, 2500Vrms isolation, 45kV/µs CMTI, AEC-Q100 automotive grade.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Grade":"Automotive","Package":"Tray","Technology":"Capacitive Coupling","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"14-VDFN","Approval Agency":"CQC, CSA, UR, VDE","lifecycle_stage":"eol_hot","Number of Channels":"2","Voltage - Isolation":"2500Vrms","Current - Peak Output":"4A","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"12ns, 12ns","Supplier Device Package":"14-QFN (5x5)","Voltage - Output Supply":"6.5V ~ 24V","Current - Output High, Low":"2A, 4A","Pulse Width Distortion (Max)":"5.6ns","Propagation Delay tpLH / tpHL (Max)":"60ns, 60ns","Common Mode Transient Immunity (Min)":"45kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.43","stockQuantity":16,"priceTiers":[{"qty":1,"price":"$5.43000","currency":"USD"},{"qty":10,"price":"$4.88000","currency":"USD"},{"qty":25,"price":"$4.61320","currency":"USD"},{"qty":80,"price":"$3.99813","currency":"USD"},{"qty":230,"price":"$3.79304","currency":"USD"},{"qty":490,"price":"$3.40349","currency":"USD"},{"qty":980,"price":"$2.87042","currency":"USD"},{"qty":2450,"price":"$2.72690","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7ce217f684032288280545b4eed821ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SI8234AB-D-IM1 and SI8235AB-D-IM1?","answer":"Both share the same 4 A peak output, 2500Vrms isolation, 45 kV/µs CMTI, and AEC-Q100 qualification.
