It uses capacitive coupling technology to deliver 3750Vrms isolation between input and output, making it suitable for driving power switches in automotive and industrial inverter stages. The AEC-Q100 Grade 1 qualification means it has passed the reliability stress tests required for engine-bay and transmission-control ECUs. ## 600mA peak drive with 35kV/µs transient immunity Peak output current is 600mA, with high/low sourcing of 400mA and 600mA respectively. This drives the gate capacitance of medium-power IGBTs and SiC MOSFETs without an external booster stage. Common-mode transient immunity is a minimum of 35kV/µs. In a motor-drive or DC-DC converter, the switching node swings hundreds of volts in tens of nanoseconds; the isolator's internal capacitive barrier rejects that dV/dt edge so the controller side sees a clean signal. Propagation delay is 60ns (tpLH) and 50ns (tpHL) maximum, with a pulse-width distortion of 28ns max. Rise and fall times are 5.5ns and 8.5ns typical. These numbers keep the switching dead-time predictable and the output waveform edges sharp enough for 100kHz+ PWM. Approvals include CQC, CSA, UR, and VDE.","metaTitle":"Skyworks SI8261AAC-C-IS Digital Isolator, 3750Vrms, 600mA","metaDescription":"Skyworks SI8261AAC-C-IS single-channel gate-drive digital isolator, 3750Vrms isolation, 600mA peak output, AEC-Q100, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tube","Technology":"Capacitive Coupling","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Approval Agency":"CQC, CSA, UR, VDE","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"3750Vrms","Current - Peak Output":"600mA","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"5.5ns, 8.5ns","Supplier Device Package":"8-SOIC","Voltage - Output Supply":"6.5V ~ 30V","Current - Output High, Low":"400mA, 600mA","Pulse Width Distortion (Max)":"28ns","Voltage - Forward (Vf) (Typ)":"2.8V (Max)","Current - DC Forward (If) (Max)":"30 mA","Propagation Delay tpLH / tpHL (Max)":"60ns, 50ns","Common Mode Transient Immunity (Min)":"35kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.06","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.06000","currency":"USD"},{"qty":10,"price":"$2.75000","currency":"USD"},{"qty":25,"price":"$2.59960","currency":"USD"},{"qty":100,"price":"$2.25300","currency":"USD"},{"qty":250,"price":"$2.13748","currency":"USD"},{"qty":500,"price":"$1.91796","currency":"USD"},{"qty":1000,"price":"$1.63500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/914a87a51f46db2f4232cb10223c5088.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between SI8261AAC-C-IS and SI8261AAC-C-IPR?","answer":"The SI8261AAC-C-IS ships in tube packaging; the SI8261AAC-C-IPR is the same die and electrical specification in tape-and-reel packaging.
