Product details
Overview
SI86S662BC-IS1R from Skyworks Solutions is a 6-channel reinforced digital isolator with 6000 VRMS isolation, 150 Mbps data rate, and dual 2.25–5.5 V supply operation. It features tri-state outputs with enable, selectable fail-safe default-high/low output, and operates across –40 to 125 °C for use in isolated motor control gate drivers and battery management system signal interfaces.
For engineers reviewing the SI86S662BC-IS1R datasheet, SI86S662BC-IS1R pinout, SI86S662BC-IS1R application, or SI86S662BC-IS1R equivalent, key selection criteria include reinforced IEC 60747-17 certification, 10 ns typical propagation delay, 3.5 ns pulse width distortion, transient immunity ≥100 kV/µs, and WB SOIC-16 package compatibility with 8 mm creepage/clearance.
Technical Context
The SI86S662BC-IS1R implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and providing superior noise immunity versus pulse-based schemes. Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.
All six channels are bidirectional-capable via external enable control (EN1/EN2), and the device supports fail-safe output states during unpowered conditions on either side. The HF XMTR/RCVR labeling in pin diagrams confirms high-frequency carrier modulation circuitry integrated per channel, not optical or capacitive coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, isolated ADC/DAC interfaces, and real-time motor control feedback loops. |
| Isolation rating | 6000 VRMS for 1 minute - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for industrial and automotive safety-critical systems. |
| Propagation delay | 10 ns typical - enables precise timing alignment in closed-loop power converter control and fast-response protection circuits. |
| Pulse width distortion | 3.5 ns typical - preserves duty cycle integrity for PWM signals crossing isolation barrier in gate driver applications. |
| Transient immunity | ≥100 kV/µs - ensures robust operation in high-noise environments like traction inverters and onboard chargers with fast-switching SiC/GaN devices. |
| Supply voltage | 2.25–5.5 V per side - allows direct interface with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
Pinout & Package
SI86S662BC-IS1R is housed in a wide-body SOIC-16 (WB SOIC-16) package with 8.0 mm minimum creepage and clearance, supporting 6000 VRMS isolation. Pin numbering follows standard SOIC-16 layout (pin 1 index mark at top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Independent supply inputs | Side A and Side B each require local 0.1 µF + 10 µF bypassing; no shared supply required for galvanic isolation integrity. |
| GND1, GND2 | Isolated ground references | Must be routed on separate PCB planes; no direct connection permitted across isolation barrier. |
| A1–A6 | Side A digital I/O | Bidirectional channels; logic levels referenced to VDD1; Schmitt-trigger inputs ensure noise rejection. |
| B1–B6 | Side B digital I/O | Bidirectional channels; logic levels referenced to VDD2; output drive strength matches 50 Ω transmission line impedance. |
| EN1, EN2 | Active-high output enable | Tri-states all outputs on respective side; used for bus arbitration and low-power sleep sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF carrier modulation eliminates boot sequence delays-output follows input immediately after UVLO exit (~0.3 ms). |
| Selectable fail-safe mode | Ordering option determines default output state (high or low) when VDDx is unpowered-critical for safe shutdown in BMS and inverter control. |
| Tri-state outputs with enable | EN1/EN2 pins allow dynamic bus contention avoidance in multi-master isolated communication systems. |
| Schmitt trigger + CMOS thresholds | Input hysteresis ≥0.15 × VDDx rejects >36 ns noise pulses-enables reliable operation in EMI-heavy motor drive environments. |
| Reinforced IEC 60747-17 rating | Validated for functional safety applications requiring dual insulation barriers-supports ASIL-D and SIL-3 system architectures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6601ARIZ-RL | Integrated isolated DC-DC converter (500 mW); 6-channel; 25 Mbps max; 2.5 kVRMS isolation; SOIC-32 package. | Eliminates need for external isolated power supply but trades off speed and isolation rating for power integration. | Choose ADUM6601ARIZ-RL when board space is constrained and isolated bias is unavailable-but avoid where 150 Mbps or 6 kVRMS is required. |
| ISO6760FDWR | 6-channel; 50 Mbps; 5000 VRMS; 16-pin SOIC; no fail-safe option; TI's capacitive isolation technology. | Lacks selectable default output state and has lower transient immunity (85 kV/µs); RoHS-compliant but not AEC-Q100 qualified. | Choose ISO6760FDWR for cost-sensitive industrial PLC I/O modules where AEC-Q100 and 6 kVRMS are not mandated. |
Compared with ADUM6601ARIZ-RL and ISO6760FDWR, SI86S662BC-IS1R delivers the highest combination of speed (150 Mbps), isolation (6000 VRMS), and automotive qualification-making it optimal for next-generation EV powertrain and industrial servo drive designs requiring both performance and safety certification.

FAQ
What is the isolation voltage rating and safety certification status of SI86S662BC-IS1R?
SI86S662BC-IS1R is rated for 6000 VRMS isolation per UL 1577 for 1 minute and carries reinforced insulation certification per IEC 60747-17. It also meets CSA 62368-1 and 60601-1, VDE 60747-17, and CQC GB4943.1 standards. These certifications are fully documented in Skyworks' official safety file for SI86S662BC-IS1R and apply directly to the WB SOIC-16 package configuration.
Does SI86S662BC-IS1R support fail-safe output behavior during power loss?
Yes, SI86S662BC-IS1R offers a factory-selectable fail-safe mode that determines whether outputs default to logic high or logic low when one side's supply is unpowered. This behavior is defined at order time and is implemented via internal configuration-no external components are needed. The SI86S662BC-IS1R variant uses the default-low option per its part number suffix.
What are the supply bypassing requirements for SI86S662BC-IS1R?
SI86S662BC-IS1R requires two bypass capacitors per side: a 0.1 µF ceramic capacitor and a 10 µF bulk capacitor placed as close as possible between VDD1–GND1 and VDD2–GND2. These values are mandatory per Skyworks' layout guidelines to maintain RF carrier stability and meet specified CMTI performance. No additional ferrite beads or series resistors are required unless system-level EMI testing indicates otherwise.
Can SI86S662BC-IS1R be used in AEC-Q100 qualified automotive applications?
Yes, SI86S662BC-IS1R is explicitly AEC-Q100 qualified (Grade 1, –40 to 125 °C) and supported with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and automotive-specific manufacturing flow validation. It is approved for use in onboard chargers, battery management systems, and traction inverters per Skyworks' automotive product release documentation for SI86S662BC-IS1R.
What is the meaning of "HF XMTR" and "HF RCVR" labels on SI86S662BC-IS1R pin diagrams?
"HF XMTR" and "HF RCVR" denote the internal high-frequency transmitter and receiver circuitry associated with each isolation channel. Unlike optocouplers or capacitive isolators, SI86S662BC-IS1R uses RF on/off keying-these labels confirm the presence of dedicated oscillator, modulator, and demodulator blocks per channel, enabling its 150 Mbps capability and immunity to magnetic fields.
