Product details
Overview
SI86S610EE-AS4 from Skyworks Solutions is a single-channel, high-speed digital isolator with reinforced 6000 VRMS isolation, AEC-Q100 qualification, and selectable fail-safe output (default low). It operates from 2.25–5.5 V, delivers 150 Mbps data rate, 10 ns typical propagation delay, and supports industrial automation, battery management systems, and isolated ADC/DAC interfaces.
For engineers reviewing the SI86S610EE-AS4 datasheet, SI86S610EE-AS4 pinout, SI86S610EE-AS4 application, or SI86S610EE-AS4 equivalent, this page provides verified technical context, real-world timing behavior, safety-certified insulation specs, and automotive-grade supply sequencing details critical for high-reliability isolated signal transmission in EV traction inverters and medical electronics.
Technical Context
The SI86S610EE-AS4 uses RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual independent UVLO and reset monitors (RSTB± ~1.7 V) ensure deterministic fail-safe behavior during asymmetric power loss on Side A or Side B.
It implements Schmitt-trigger + CMOS threshold inputs for high noise rejection, supports 100 kV/µs common-mode transient immunity (CMTI), and features internal 50 Ω output impedance matched to controlled-impedance PCB traces-enabling clean 150 Mbps eye diagrams with ≤350 ps peak jitter.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps - enables high-fidelity serial communication in motor control gate drivers and isolated SPI interfaces |
| Propagation delay | 5–14 ns (typ. 10 ns) - ensures tight timing alignment in real-time feedback loops for power converters |
| Isolation rating | 6000 VRMS (1 min) - meets UL 1577 and IEC 60747-17 reinforced insulation for 1500 VRMS working voltage in SSO-8 package |
| Supply range | 2.25–5.5 V per side - supports interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level shifters |
| Fail-safe mode | Default low output - maintains safe logic state during VDD1 loss while VDD2 remains active, critical for BMS fault signaling |
| Operating temperature | –40 to +125 °C - qualified for under-hood automotive use and industrial PLC environments |
| CMTI | 100 kV/µs - suppresses false triggering in high-dV/dt environments like SiC/GaN inverter switching nodes |
Pinout & Package
SI86S610EE-AS4 is housed in an SSO-8 (wide-body SOIC-8) package with 8.0 mm creepage/clearance, optimized for 6000 VRMS isolation. Pin 1 = VDD1, Pin 2 = A1 (input), Pin 3 = NC, Pin 4 = GND1, Pin 5 = GND2, Pin 6 = B1 (output), Pin 7 = VDD2, Pin 8 = NC - confirmed per Figure 1 and Table 1 of datasheet 206552B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Independent power supplies | Enable galvanic separation of logic domains; each side powers its own circuitry without shared ground reference |
| A1 | Side A input | Accepts CMOS/Schmitt-trigger signals up to 150 Mbps; internally pulled down in default-low configuration |
| B1 | Side B output | Drives 50 Ω loads directly; fails low when VDD1 is unpowered but VDD2 remains active |
| GND1, GND2 | Isolated grounds | Physically separate return paths prevent ground-loop currents between high-noise and sensitive analog sections |
| NC (Pins 3 & 8) | No-connect terminals | Must remain unconnected to preserve isolation barrier integrity and creepage distance compliance |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot delay-valid output appears within 300 µs of VDD stabilization |
| Selectable fail-safe output | Ordering code "E" denotes default-low behavior, ensuring safe shutdown state during input-side power loss |
| High electromagnetic immunity | 100 kV/µs CMTI and 8 kV HBM ESD rating protect against fast transients in motor drives and charging stations |
| Reinforced safety certification | UL 1577 (6000 VRMS), VDE 60747-17, CSA 62368-1, and CQC GB4943.1 approvals enable system-level compliance |
| Wide temperature operation | –40 to +125 °C junction range supports placement near power stages in EV onboard chargers and inverters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM110N0BRZ-RL7 | Single-channel, 150 Mbps, 3.75 kVRMS isolation, 2.7–5.5 V supply, no AEC-Q100 qualification | Suitable for industrial/commercial use only; lacks automotive qualification and 6 kVRMS rating required for OBC/BMS | Choose for cost-sensitive non-automotive designs where 3.75 kVRMS suffices and fail-safe default state is not mandatory |
| ISO6710DR | Single-channel, 50 Mbps, 5000 VRMS, 2.25–5.5 V, AEC-Q100 Grade 1, default-high fail-safe option only | Limited to 50 Mbps; cannot support high-speed SPI or fast gate driver signaling in SiC/GaN inverters | Choose when lower data rate is acceptable and default-high output aligns with system fault strategy |
Compared with ADUM110N0BRZ-RL7 and ISO6710DR, SI86S610EE-AS4 uniquely combines 150 Mbps speed, 6000 VRMS reinforced isolation, AEC-Q100 Grade 0 qualification, and default-low fail-safe behavior-making it the only option qualified for high-reliability, high-speed signal isolation in automotive traction inverters and medical diagnostic equipment.

FAQ
What is the isolation voltage rating of SI86S610EE-AS4 and which safety standards does it meet?
SI86S610EE-AS4 is rated for 6000 VRMS isolation per UL 1577 (1 minute), with reinforced insulation certified to VDE 60747-17, CSA 62368-1, and CQC GB4943.1. Its SSO-8 package achieves 8.0 mm creepage and clearance, supporting 1500 VRMS working voltage in end-equipment compliant with IEC 61010-1 and IEC 62368-1.
Does SI86S610EE-AS4 require external bypass capacitors, and if so, what values are recommended?
Yes, SI86S610EE-AS4 requires 0.1 µF and 10 µF bypass capacitors between VDD1–GND1 and VDD2–GND2. These must be placed as close as possible to the package pins to suppress high-frequency noise and ensure stable operation during fast switching events in motor control or power conversion circuits.
How does the fail-safe mode of SI86S610EE-AS4 behave during power loss on the input side?
SI86S610EE-AS4 is ordered with default-low fail-safe behavior ("E" suffix). When VDD1 drops below UVLO– (~2.05 V) while VDD2 remains powered, the B1 output transitions to and holds logic low within 12 ns (tSD), providing a known safe state for downstream fault-handling logic in battery management or medical systems.
What is the maximum data rate supported by SI86S610EE-AS4, and how does propagation delay vary with supply voltage?
SI86S610EE-AS4 supports up to 150 Mbps. Propagation delay ranges from 5–13.5 ns (typ. 10 ns) at 5.0 V, 5–14 ns at 3.3 V, and 6.5–17 ns at 2.5 V-verified across –40 to +125 °C. This tight delay budget enables precise timing in closed-loop motor control and isolated ADC sampling clocks.
Is SI86S610EE-AS4 qualified for automotive applications, and what grade does it meet?
Yes, SI86S610EE-AS4 is AEC-Q100 qualified to Grade 0 (–40 to +150 °C ambient), with full PPAP documentation support and IMDS/CAMDS compliance. It is designed for automotive applications including onboard chargers, battery management systems, and traction inverters in battery electric vehicles.
