The 4 A peak output current, with 500 mA source and 1.2 A sink capability, drives the gate charge of medium-power IGBTs and SiC MOSFETs through the Miller plateau region without excessive voltage sag on the secondary-side supply rail. Propagation delay is 60 ns max on the low-to-high edge and 50 ns max on the high-to-low edge, with pulse-width distortion held to 28 ns max — these timing specs set the minimum achievable dead-time in a half-bridge PWM path and determine whether the controller's dead-time register can compensate without adding margin. ## Transient immunity and switching-speed parametrics Common-mode transient immunity is rated at 35 kV/µs minimum — during a fast switching event on the high-voltage bus (an IGBT turn-off or SiC hard-switching edge), the isolation capacitor couples a displacement current across the barrier; the receiver must reject that common-mode step to avoid a false output transition. At 35 kV/µs the part holds the gate signal clean through the transient. Rise and fall times are 5.5 ns and 8.5 ns typical respectively — these edges drive the gate capacitance without the slow slew that extends switching losses, but the PCB layout must keep the gate-loop inductance below 10 nH to avoid overshoot on the falling edge. The output supply range spans 6.5 V to 30 V, allowing the secondary side to operate from a regulated 12 V auxiliary rail for standard IGBTs or a 15 V rail for SiC FETs that need a higher gate-drive voltage to minimise Rds(on). ## Package, approvals, and lifecycle Safety approvals include CQC (China), CSA (Canada), UR (UL Recognized), and VDE (Germany) — these four certifications cover the major regional safety standards for reinforced insulation in power-converter designs shipped to Asia, North America, and Europe. The part is suitable for new design-ins and existing production BOMs without a last-time-buy window to manage.","metaTitle":"Skyworks SI8261BAD-C-IS Digital Isolator, 5000Vrms, AEC-Q100","metaDescription":"Skyworks SI8261BAD-C-IS single-channel gate-drive digital isolator, 5000 Vrms isolation, 4 A peak output, 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":"Tube","Technology":"Capacitive Coupling","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"6-SOIC (0.295\\\", 7.50mm Width)","Approval Agency":"CQC, CSA, UR, VDE","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Current - Peak Output":"4A","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"5.5ns, 8.5ns","Supplier Device Package":"6-SDIP Gull Wing","Voltage - Output Supply":"6.5V ~ 30V","Current - Output High, Low":"500mA, 1.2A","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":"$4.28","stockQuantity":28,"priceTiers":[{"qty":1,"price":"$4.28000","currency":"USD"},{"qty":10,"price":"$3.84600","currency":"USD"},{"qty":25,"price":"$3.63600","currency":"USD"},{"qty":100,"price":"$3.15120","currency":"USD"},{"qty":250,"price":"$2.98960","currency":"USD"},{"qty":500,"price":"$2.68256","currency":"USD"},{"qty":1000,"price":"$2.26240","currency":"USD"},{"qty":2500,"price":"$2.14928","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/914a87a51f46db2f4232cb10223c5088.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the SI8261BAD-C-IS and what is the typical lead time?","answer":"Submit an RFQ for the specific quantity and target delivery window."},{"question":"What is the difference between SI8261BAD-C-IS and SI8261BAD-C-ISR?","answer":"The SI8261BAD-C-IS ships in tube packaging; the SI8261BAD-C-ISR is the tape-and-reel variant. The die, isolation rating, output current, timing specs, and automotive qualification are identical. The only difference is the packaging format for automated pick-and-place assembly."},{"question":"Will SI8261BAD-C-IS drop into a board designed for SI8261BBD-C-IS?","answer":"Both parts share the same 6-SOIC wide-body package (7.50 mm width, SDIP Gull Wing leads) and the same pinout. The electrical ratings are identical for isolation, output current, timing, and temperature range. The internal configuration differs — verify the BOM position's logic polarity and enable function before substituting without a design review."},{"question":"What compliance documentation does Skyworks provide for the SI8261BAD-C-IS?","answer":"The part is ROHS3 compliant. Safety approvals include CQC, CSA, UR, and VDE — these certifications cover reinforced insulation for power-converter designs.
