Product details
Overview
SI86S660BE-IS2R 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 implements RF-based on/off keying across a semiconductor isolation barrier for high-noise immunity in isolated power control, motor drive feedback, and battery management systems.
For engineers reviewing the SI86S660BE-IS2R datasheet, SI86S660BE-IS2R pinout, SI86S660BE-IS2R application, or SI86S660BE-IS2R equivalent, this page delivers verified specifications, fail-safe output behavior during unpowered conditions, tri-state enable control per side, Schmitt-trigger inputs, and AEC-Q100 qualification for automotive traction inverter and onboard charger designs.
Technical Context
The SI86S660BE-IS2R uses RF modulation (not optical or capacitive) to transmit logic states across its isolation barrier, enabling no-startup-initialization operation and 100 kV/µs CMTI immunity. Its architecture supports independent UVLO monitoring per side (VDD1/VDD2), RSTB reset thresholds (~1.7 V), and configurable default output state (high/low) during supply loss.
It features six bidirectional I/O channels (A1–A6/B1–B6), two active-high enable pins (EN1/EN2), and operates across –40 °C to +125 °C. The device is packaged in a WB SOIC-16 with 8.3 mm creepage/clearance and certified to IEC 60747-17 (reinforced), UL 1577 (6000 VRMS), and CSA/GB4943.1 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, QSPI, and real-time control loop signaling without protocol translation. |
| Isolation rating | 6000 VRMS (1 min) - enables use in reinforced insulation applications including 1000 V DC battery systems and industrial AC mains interfaces. |
| Propagation delay | 10 ns typical - ensures tight timing alignment between isolated controller and power stage in motor drives and inverters. |
| Supply voltage | 2.25–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V gate drivers without level-shifting. |
| Pulse width distortion | 3.5 ns typical - preserves duty cycle integrity for PWM signals used in isolated gate driving and ADC sampling clocks. |
| CMTI immunity | ≥100 kV/µs - prevents false triggering in high-dV/dt environments like SiC/GaN half-bridges and fast-switching SMPS. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
| Safety certifications | UL 1577, VDE 60747-17, CSA 62368-1/60601-1, CQC GB4943.1 - satisfies end-equipment compliance for medical, industrial, and EV systems. |
Pinout & Package
SI86S660BE-IS2R is housed in a wide-body SOIC-16 (WB SOIC-16) package with 8.3 mm creepage and clearance, supporting 6000 VRMS isolation. Pin numbering follows standard SOIC-16 layout (pin 1 = VDD1, pin 16 = VDD2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Independent power supplies | Side A and Side B each require local 0.1 µF + 10 µF bypassing; no shared supply required. |
| GND1, GND2 | Isolated ground references | Must be kept physically separated on PCB to maintain creepage/clearance and avoid coupling noise across barrier. |
| A1–A6, B1–B6 | Bidirectional digital I/O channels | Each channel supports 100 Mbps+ data flow in either direction; no internal direction control logic required. |
| EN1, EN2 | Active-high output enable | EN1 controls all B-side outputs; EN2 controls all A-side outputs; both support tri-state during sleep or fault conditions. |
| NC | No-connect terminal | Pin 7 and pin 14 are internally unused; must remain unconnected per datasheet Figure 4. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates startup initialization delay and provides superior magnetic field immunity vs. optocouplers or capacitive isolators. |
| Selectable fail-safe output mode | Ordering option defines default output state (high or low) when VDD1 is unpowered but VDD2 remains active - critical for safe shutdown in BMS. |
| Schmitt-trigger + CMOS threshold inputs | Ensures robust noise rejection on noisy industrial buses (e.g., encoder lines, current sense amplifiers) without external hysteresis components. |
| Tri-state outputs with enable | EN1/EN2 allow synchronized disabling of all outputs on respective sides - enables bus sharing and hot-swap capability in modular systems. |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications up to +125 °C ambient, including onboard chargers and traction inverters in BEV/HEV platforms. |
| Transient immunity ≥100 kV/µs | Guarantees reliable operation during fast switching transients in SiC/GaN power stages without spurious toggling or latch-up. |

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, 5000 VRMS, 25 Mbps max, integrated isolated DC-DC converter | Requires no external isolated supply but trades off speed and CMTI (50 kV/µs) | Choose ADUM6600ARIZ-RL when board space is constrained and isolated power is unavailable; SI86S660BE-IS2R preferred for high-speed, high-CMTI motor control. |

FAQ
What is the isolation voltage rating and safety certification status of SI86S660BE-IS2R?
SI86S660BE-IS2R is rated for 6000 VRMS isolation per UL 1577 (1 minute) and certified to IEC 60747-17 (reinforced), CSA 62368-1/60601-1, and CQC GB4943.1. These approvals are documented in Skyworks' official safety report and apply directly to the SI86S660BE-IS2R part number in its WB SOIC-16 package.
Does SI86S660BE-IS2R support fail-safe output configuration, and how is it implemented?
Yes, SI86S660BE-IS2R offers selectable fail-safe output behavior via ordering option: default high or default low output state when VDD1 is unpowered but VDD2 remains active. This is implemented using internal configuration fuses set at manufacturing - no external circuitry or software configuration is required for SI86S660BE-IS2R.
What are the supply bypass requirements for SI86S660BE-IS2R?
SI86S660BE-IS2R requires 0.1 µF ceramic + 10 µF bulk capacitors placed between VDD1–GND1 and VDD2–GND2, with both capacitors located within 5 mm of their respective pins. This dual-capacitor network suppresses high-frequency switching noise and maintains stable operation during transient load changes.
Can SI86S660BE-IS2R be used in automotive traction inverter designs?
Yes, SI86S660BE-IS2R is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C) and certified to IEC 60747-17 reinforced insulation - meeting core requirements for traction inverter gate driver isolation in battery electric vehicles. Its 100 kV/µs CMTI and 10 ns propagation delay support SiC/GaN switching speeds up to 200 kHz.
How does the EN1 and EN2 pin functionality work on SI86S660BE-IS2R?
EN1 is an active-high enable controlling all B-side outputs (B1–B6); EN2 controls all A-side outputs (A1–A6). When low, both pins place their respective side's outputs in high-impedance tri-state - enabling bus arbitration, power sequencing, and safe shutdown in fault conditions for SI86S660BE-IS2R.
