Product details
Overview
SI86S662EB-IUR from Skyworks Solutions is a 6-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and dual 2.25–5.5 V supply operation. It features Schmitt-trigger + CMOS inputs, tri-state outputs with enable, selectable fail-safe (default high/low), and operates across –40 to 125 °C for automotive and industrial isolated communication interfaces.
For engineers reviewing the SI86S662EB-IUR datasheet, SI86S662EB-IUR pinout, SI86S662EB-IUR application, or SI86S662EB-IUR equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade AEC-Q100 qualification, IEC 60747-17 reinforced insulation compliance, and real-world use cases in battery management systems and motor control inverters.
Technical Context
The SI86S662EB-IUR implements RF-based on/off keying modulation across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity. 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 behavior.
It integrates six bidirectional digital channels with side-specific enable pins (EN1/EN2), supports simultaneous forward/reverse data flow, and delivers precise timing: 10 ns typical propagation delay and 3.5 ns pulse width distortion. Transient immunity exceeds 100 kV/µs, meeting stringent CMTI requirements for high-noise power electronics environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, CAN FD, and isolated ADC/DAC interfaces without protocol translation. |
| Isolation rating | 6000 VRMS (1 min) - enables reinforced insulation per UL 1577, VDE 60747-17, and IEC 62368-1 for safety-critical systems. |
| Supply voltage | 2.25–5.5 V per side - allows interoperability with 3.3 V and 5 V logic domains and simplifies mixed-voltage system design. |
| Propagation delay | 10 ns typical - ensures tight timing alignment in closed-loop motor control and real-time feedback paths. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive applications including onboard chargers and traction inverters. |
| CMTI | >100 kV/µs - prevents false triggering in high-dV/dt environments such as SiC/GaN power stages and PWM gate drivers. |
| AEC-Q100 grade | Qualified - meets stress test requirements for automotive electronics, including HTOL, TCT, and ESD per Grade 1. |
Pinout & Package
SI86S662EB-IUR uses a WB SOIC-16 (wide-body small-outline integrated circuit) package with 16 pins and creepage/clearance optimized for 6000 VRMS working voltage. Pin numbering follows standard SOIC convention (pin 1 = top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A power supply | Supplies 2.25–5.5 V to input-side logic and transmitters; requires 0.1 µF + 10 µF bypass capacitors. |
| GND1 | Side A ground | Reference return for VDD1; must be separated from GND2 by ≥8 mm creepage for reinforced insulation compliance. |
| A1–A6 | Side A digital I/O | Input/output channels on primary side; support CMOS/Schmitt thresholds and tolerate ±0.5 V beyond rail. |
| EN1 | Side A output enable | Active-high control: drives all A-side outputs into high-impedance when low; enables synchronized channel disable. |
| VDD2 | Side B power supply | Independent 2.25–5.5 V supply for isolated side; decoupling identical to VDD1. |
| GND2 | Side B ground | Isolated reference for VDD2; forms safety barrier with GND1; no direct connection permitted. |
| B1–B6 | Side B digital I/O | Corresponding isolated outputs/inputs; electrically and functionally matched to A1–A6. |
| EN2 | Side B output enable | Active-high control for B-side outputs; allows independent tri-state control of isolated domain. |
Key Features
| Feature | Design Value |
|---|---|
| No-startup initialization | RF modulation architecture eliminates boot sequence delays - outputs become valid within 0.3 ms of VDD stabilization. |
| Selectable fail-safe mode | Ordering option defines default output state (high or low) during VDD1/VDD2 brownout - critical for safe shutdown in BMS. |
| Tri-state outputs with enable | EN1/EN2 pins provide single-point control over all six channels per side - simplifies bus arbitration and reduces external logic. |
| Schmitt-trigger + CMOS inputs | Combined threshold improves noise margin in noisy industrial environments while maintaining compatibility with standard logic families. |
| Reinforced IEC 60747-17 rating | Validated insulation structure meets reinforced isolation requirements for medical (60601-1) and industrial (62368-1) end equipment. |

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 | 6-channel, 5000 VRMS, 25 Mbps max, integrated isolated DC-DC converter | Provides isolated power but lower data rate; not AEC-Q100 qualified | Choose ADUM6601ARIZ-RL only if auxiliary isolated supply is required and 25 Mbps suffices. |
| ISO6760FRDWR | 6-channel, 5000 VRMS, 50 Mbps, 2.25–5.5 V, no fail-safe option | Lacks selectable default output state; rated for industrial but not automotive temperature range | Choose ISO6760FRDWR for cost-sensitive industrial PLC I/O modules where fail-safe is not mandated. |
Compared with ADUM6601ARIZ-RL and ISO6760FRDWR, SI86S662EB-IUR uniquely combines 150 Mbps speed, 6000 VRMS reinforced isolation, AEC-Q100 qualification, and programmable fail-safe behavior - making it the only option suitable for high-performance automotive traction inverter control and medical imaging subsystems requiring both speed and safety certification.

FAQ
What is the isolation voltage rating of SI86S662EB-IUR and which safety standards does it meet?
SI86S662EB-IUR provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 (reinforced insulation), IEC 62368-1, and IEC 60601-1. It also holds pending CQC GB4943.1 approval. These ratings are validated for the WB SOIC-16 package and apply directly to SI86S662EB-IUR - not extrapolated from other variants.
Does SI86S662EB-IUR support fail-safe operation, and how is it configured?
Yes, SI86S662EB-IUR offers factory-configurable fail-safe mode: default high or default low output during input-side power loss. This is implemented via ordering option (denoted in suffix); SI86S662EB-IUR is the default-low variant. Configuration is fixed at manufacture and cannot be changed in-circuit.
What are the supply voltage requirements for SI86S662EB-IUR, and can VDD1 and VDD2 operate at different voltages?
SI86S662EB-IUR supports independent 2.25–5.5 V supplies on VDD1 and VDD2. They may differ - e.g., VDD1 = 3.3 V (controller side), VDD2 = 5.0 V (gate driver side) - with no impact on timing or isolation integrity. Each side requires dedicated 0.1 µF + 10 µF bypassing.
How does SI86S662EB-IUR handle power-up sequencing when VDD1 and VDD2 ramp at different rates?
SI86S662EB-IUR includes independent UVLO and reset circuits per side. If VDD1 powers up before VDD2, outputs remain in fail-safe state (low for SI86S662EB-IUR) until VDD2 crosses its UVLO+ threshold (~2.18 V). Startup time from unpowered to valid output is 0.3 ms after VDD stabilization.
Is SI86S662EB-IUR qualified for automotive applications, and what evidence supports this claim?
Yes, SI86S662EB-IUR is AEC-Q100 qualified (Grade 1, –40 to 125 °C). This qualification is documented in Skyworks' official product documentation and supported by AIAG-compliant PPAP, IMDS/CAMDS listings, and automotive-specific manufacturing process flows - all confirmed for SI86S662EB-IUR specifically.
