Product details
Overview
SI86S660BB-AUR from Skyworks Solutions is a 6-channel, bidirectional digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger + CMOS inputs, tri-state outputs with enable, selectable fail-safe default-high/low output, and operates across –40 to 125 °C in WB SOIC-16 package. It is used in traction inverters and battery management systems where high-speed signal integrity and safety-critical isolation are required.
For engineers reviewing the SI86S660BB-AUR datasheet, SI86S660BB-AUR pinout, SI86S660BB-AUR application, or SI86S660BB-AUR equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options - all aligned to the exact ordering part number and its documented electrical, thermal, and safety characteristics.
Technical Context
The SI86S660BB-AUR implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling deterministic timing behavior. Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with 100 kΩ weak pulldown during unpowered states and configurable fail-safe output polarity.
It integrates six isolated I/O channels (A1–A6/B1–B6), dual enable inputs (EN1/EN2), and operates with 2.25–5.5 V supplies on both sides. The device meets reinforced insulation requirements per IEC 60747-17 and UL 1577 (6000 VRMS, 1 min), with transient immunity ≥100 kV/µs and CMTI performance consistent with high-noise motor control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed serial interfaces including isolated SPI and QSPI clock domains. |
| Isolation rating | 6000 VRMS (1 min) - enables use in reinforced insulation applications such as onboard chargers and traction inverters per IEC 62368-1 and 60601-1. |
| Propagation delay | 10 ns typical - ensures tight timing alignment between isolated controller and power stage signals in motor drives. |
| Pulse width distortion | 3.5 ns typical - preserves duty cycle fidelity critical for PWM feedback and gate driver timing. |
| Supply voltage | 2.25–5.5 V per side - allows interoperability with 3.3 V and 5 V logic domains without level shifters. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive environments and industrial motor control enclosures. |
| Transient immunity | ≥100 kV/µs - suppresses fast common-mode noise from IGBT/SiC switching transients in inverters. |
Pinout & Package
SI86S660BB-AUR is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance optimized for 6000 VRMS reinforced insulation. Pin 1 is marked with a dot; the isolation barrier separates Side A (pins 1–8) and Side B (pins 9–16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides bias for transmitter circuits on input side; requires 0.1 µF + 10 µF bypassing per side. |
| A1–A6 | Side A digital I/O | Unidirectional or bidirectional isolated data paths; compatible with CMOS/Schmitt-trigger logic thresholds. |
| EN1 | Side A output enable | Active-high control for tristating all Side A outputs - enables centralized power-down of isolated interface. |
| VDD2, GND2 | Side B power supply | Independent bias for receiver circuits; supports galvanic separation between control and power domains. |
| B1–B6 | Side B digital I/O | Corresponding isolated outputs/inputs mirroring A1–A6; maintains channel-by-channel signal integrity. |
| EN2 | Side B output enable | Active-high control for tristating all Side B outputs - supports asymmetric power management per side. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot-time delays - outputs become valid within 0.3 ms after VDD rise above UVLO+. |
| Selectable fail-safe mode | Ordering option defines default output state (high or low) during VDD1/VDD2 undervoltage - prevents undefined gate drive in BMS fault conditions. |
| Tri-state outputs with enable | EN1/EN2 pins allow dynamic bus contention avoidance in multi-master isolated SPI or CAN FD interfaces. |
| Schmitt trigger + CMOS inputs | Input hysteresis ≥0.15 × VDDx improves noise margin against EMI in high-dV/dt motor control environments. |
| AEC-Q100 qualification | Qualified to Grade 0 (–40 to +150 °C junction) - validates reliability for automotive traction inverter gate drive isolation. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6601ARWZ | 6-channel, 50 Mbps, 3750 VRMS, integrated isolated DC-DC converter, SOIC-16W | Lacks AEC-Q100 qualification and 6000 VRMS rating; suitable for industrial but not automotive traction systems | Choose when isolated power is needed alongside signal isolation, and 50 Mbps suffices for control loop bandwidth. |
| ISO6760FDWR | 6-channel, 50 Mbps, 5000 VRMS, 2.25–5.5 V, SOIC-16, no fail-safe option | Lower isolation rating and no configurable default output state; not certified to IEC 60747-17 | Choose for cost-sensitive industrial applications where 5000 VRMS and absence of fail-safe mode are acceptable. |
Compared with ADUM6601ARWZ and ISO6760FDWR, SI86S660BB-AUR provides higher data rate (150 Mbps vs. 50 Mbps), reinforced 6000 VRMS isolation, AEC-Q100 Grade 0 qualification, and user-selectable fail-safe output - making it uniquely suited for automotive traction inverter and high-reliability industrial motor control.

This rating applies to the WB SOIC-16 package and is validated for use in automotive onboard chargers and traction inverters meeting IEC 62368-1 and 60601-1 system requirements.
Does the SI86S660BB-AUR support fail-safe output configuration?
Yes, the SI86S660BB-AUR offers a selectable fail-safe mode via ordering option: default high or default low output state when the input supply is unpowered but the output supply remains active. This behavior is defined in Table 4 of the datasheet and ensures predictable gate driver or ADC interface behavior during brownout conditions.
What is the propagation delay and pulse width distortion of the SI86S660BB-AUR?
The SI86S660BB-AUR has a typical propagation delay of 10 ns and typical pulse width distortion of 3.5 ns, measured at VDD = 5.0 V and TA = 25 °C. These values are guaranteed over the full operating temperature range (–40 to 125 °C) and enable precise timing alignment in motor control PWM feedback loops.
Is the SI86S660BB-AUR qualified for automotive applications?
Yes, the SI86S660BB-AUR is AEC-Q100 qualified (Grade 0, –40 to +150 °C junction temperature) and built using automotive-specific manufacturing flows. It supports AIAG-compliant PPAP documentation and IMDS/CAMDS listing - fulfilling requirements for use in battery electric vehicle traction inverters and onboard chargers.
