Product details
Overview
SI86S660EB-IUR from Skyworks Solutions is a six-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and 10 ns typical propagation delay. It features dual-side supply (2.25–5.5 V), Schmitt-trigger + CMOS inputs, tri-state outputs with enable, and fail-safe default-high output mode. It is used in isolated ADC/DAC interfaces and motor control gate drivers where high CMTI and precise timing are required.
For engineers reviewing the SI86S660EB-IUR datasheet, SI86S660EB-IUR pinout, SI86S660EB-IUR application, or SI86S660EB-IUR equivalent, key selection criteria include reinforced IEC 60747-17 certification, AEC-Q100 qualification, 6-channel bidirectional isolation, sleep-mode support via SMb pin, and WB SOIC-16 package compatibility with 8 mm creepage.
Technical Context
The SI86S660EB-IUR implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity. Its architecture supports independent UVLO and reset per side (VDD1/VDD2), with RSTB thresholds at ~1.7 V and 100 kΩ weak pulldown during unpowered states.
It delivers precise timing with 3.5 ns pulse width distortion and 100 kV/µs transient immunity, while supporting fail-safe configuration (default-high) and tri-state output control via EN1/EN2 pins. The device operates across –40 to 125 °C and meets UL 1577, CSA 62368-1/60601-1, VDE 60747-17, and CQC GB4943.1 safety standards.

Pinout & Package
SI86S660EB-IUR is housed in a wide-body SOIC-16 (WB SOIC-16) package with 8.0 mm creepage and clearance, supporting 6000 VRMS isolation. Pin layout follows Figure 4 of the datasheet (Si86S660 variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power domain | Supplies and grounds the input-side logic; requires 0.1 µF + 10 µF bypass capacitors. |
| A1–A6 | Side A digital I/O | Unidirectional or bidirectional data channels; Schmitt-trigger + CMOS threshold inputs. |
| VDD2, GND2 | Side B power domain | Supplies and grounds the output-side logic; electrically isolated from Side A. |
| B1–B6 | Side B digital I/O | Corresponding isolated outputs; tri-state controllable via EN1/EN2 pins. |
| EN1, EN2 | Active-high output enable | Controls all outputs on respective side; drives outputs to high-impedance when low. |
| SMb | Sleep mode control | Active-low pin enabling ultra-low-power sleep mode (750 µA/side); retains isolation channel for wake-up. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and startup delays; achieves best-in-class CMTI and magnetic field immunity. |
| Reinforced safety certification | UL 1577, VDE 60747-17, CSA 62368-1/60601-1, CQC GB4943.1 - enables single-component compliance in medical and EV systems. |
| Fail-safe output selection | Ordering option sets default output state (high or low) during VDD1 loss - critical for safe shutdown in motor control. |
| Sleep mode with wake capability | SMb pin reduces current to 750 µA/side while retaining one active channel to monitor wake signal. |
| Tri-state output control | EN1/EN2 pins allow bus sharing and hot-swap isolation without external logic or pull-ups. |
Applications
| Isolated Motor Control | Automotive Onboard Charger |
|---|---|

IC Role / Device Role / Timing Role: Six-channel isolator transmits PWM and fault feedback across isolation barrier with <10 ns skew. Use Value: 6000 VRMS rating and 100 kV/µs CMTI prevent false triggering during fast-switching transients. | Use Scenario: Isolating communication and control signals between AC/DC front-end and DC/DC secondary in EV onboard chargers. IC Role / Device Role / Timing Role: Provides bidirectional data isolation for CAN, SPI, and analog monitoring signals across primary-secondary boundary. Use Value: AEC-Q100 qualification and –40 to 125 °C operation ensure reliability in under-hood thermal environments. |
| Isolated ADC Interface | Industrial PLC I/O Module |

IC Role / Device Role / Timing Role: Transfers serial ADC data (e.g., SPI) across isolation barrier with deterministic latency and no bit errors. Use Value: 150 Mbps data rate and 3.5 ns pulse width distortion preserve signal integrity for 16-bit+ resolution sampling. | Use Scenario: Isolating digital input/output signals between field-side sensors/actuators and controller-side logic in programmable logic controllers. IC Role / Device Role / Timing Role: Six independent channels handle discrete I/O, status reporting, and command transmission with fail-safe defaults.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6600ARIZ-RL | 6-channel, 6000 VRMS, but uses iCoupler magnetic isolation; higher quiescent current (3.5 mA/channel typical); no SMb sleep pin. | Less suitable for battery-powered or thermally constrained automotive modules requiring ultra-low sleep current. | Select ADUM6600ARIZ-RL only if magnetic isolation compatibility with existing iCoupler designs is required. |
| ISO6760FRDWR | 6-channel, 5000 VRMS (not reinforced), 50 Mbps max data rate; lower CMTI (85 kV/µs); no AEC-Q100 qualification. | Not approved for automotive traction inverters or medical equipment requiring reinforced insulation. | Choose ISO6760FRDWR only for cost-sensitive industrial controls where 5000 VRMS and non-automotive qualification suffice. |
Compared with ADUM6600ARIZ-RL and ISO6760FRDWR, SI86S660EB-IUR uniquely combines AEC-Q100 qualification, 6000 VRMS reinforced isolation, 150 Mbps speed, and 750 µA sleep current-making it optimal for next-generation EV power electronics and high-reliability industrial automation.

FAQ
What is the isolation rating and safety certification status of SI86S660EB-IUR?
SI86S660EB-IUR provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 (reinforced), CSA 62368-1/60601-1, and CQC GB4943.1. These approvals are documented in Skyworks' official safety reports and enable direct use in medical and EV traction systems without additional system-level isolation barriers. SI86S660EB-IUR meets all required creepage and clearance distances in its WB SOIC-16 package.
Does SI86S660EB-IUR support fail-safe output behavior during power loss?
Yes, SI86S660EB-IUR is ordered with default-high fail-safe mode (denoted by "E" in the part number). When VDD1 is unpowered but VDD2 remains active, outputs B1–B6 default to logic high-ensuring safe deactivation of downstream drivers or latches. This behavior is confirmed in Table 4 of the datasheet and does not require external circuitry. SI86S660EB-IUR implements this via internal configuration stored in nonvolatile memory.
What is the function of the SMb pin on SI86S660EB-IUR?
The SMb pin on SI86S660EB-IUR is an active-low sleep mode control that reduces total supply current to 750 µA per side. When pulled low, it disables all transmitter/receiver circuits except one dedicated channel that monitors SMb for wake-up. SI86S660EB-IUR exits sleep mode within 1 µs when SMb transitions high or floats. This feature is validated in Figure 11 and Section 3.4.2 of the datasheet.
Can SI86S660EB-IUR be used in automotive applications?
Yes, SI86S660EB-IUR is AEC-Q100 qualified (Grade 1, –40 to 125 °C) and supports AIAG-compliant PPAP documentation. It is specifically designed for automotive onboard chargers, battery management systems, and traction inverters. SI86S660EB-IUR undergoes automotive-specific manufacturing flows and defectivity screening, and its reinforced isolation meets ISO 26262 ASIL-B requirements for functional safety subsystems.
What are the recommended bypass capacitors for SI86S660EB-IUR?
Skyworks specifies a 0.1 µF ceramic capacitor plus a 10 µF bulk capacitor between VDD1 and GND1, and identically between VDD2 and GND2. These must be placed within 5 mm of the respective pins per Section 3.2.1. SI86S660EB-IUR's internal RF modulation architecture makes it sensitive to supply noise; omitting either capacitor risks increased jitter or intermittent communication failure. X7R dielectric is recommended for both capacitors.
