Product details
Overview
SI86S630BE-IS2 from Skyworks Solutions is a 3-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and 10 ns typical propagation delay. It features Schmitt-trigger + CMOS input thresholds, tri-state outputs with enable control, and selectable fail-safe output (default low) for industrial and automotive isolated interfaces including motor control, battery management systems, and isolated ADC/DAC.
For engineers reviewing the SI86S630BE-IS2 datasheet, SI86S630BE-IS2 pinout, SI86S630BE-IS2 application, or SI86S630BE-IS2 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in high-noise environments, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The SI86S630BE-IS2 implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and providing superior CMTI (>100 kV/µs) versus optocouplers. Its dual-supply architecture (VDD1/VDD2 = 2.25–5.5 V) supports independent side-A and side-B operation with undervoltage lockout (UVLO+ = 2.18 V) and reset (RSTB+ ≈ 1.7 V) on both sides.
It integrates tri-state output enable (EN1/EN2), failsafe default-low output mode (ordered via suffix 'E'), and operates across –40 to +125 °C. The device complies with IEC 60747-17 (reinforced insulation), UL 1577 (6000 VRMS), CSA 62368-1/60601-1, and AEC-Q100 Grade 0.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3401BRWZ | 4-channel, 100 Mbps, 2500 VRMS, SOIC-16, no fail-safe default-low option | Lacks reinforced 6000 VRMS rating and AEC-Q100 qualification - limited to non-automotive industrial use | Choose when only 2500 VRMS isolation suffices and 4 channels are required; verify UVLO behavior matches system reset profile |
| ISO6731FDWR | 3-channel, 50 Mbps, 5000 VRMS, SOIC-16, default-high fail-safe only | Lower data rate and isolation voltage; no default-low ordering option - unsuitable for BMS safe-shutdown logic | Consider for cost-sensitive, lower-speed applications where 5000 VRMS meets safety margin; confirm directionality aligns with signal flow |
Compared with SI86S630BE-IS2, ADUM3401BRWZ offers higher channel count but lacks reinforced 6000 VRMS and fail-safe low output, while ISO6731FDWR trades speed and isolation for lower cost - neither provides the combined AEC-Q100, 150 Mbps, and default-low capability required for next-gen EV and industrial servo systems.

FAQ
What is the isolation voltage rating of the SI86S630BE-IS2 and which safety standards does it meet?
The SI86S630BE-IS2 has a 6000 VRMS isolation rating per UL 1577 (1 minute). It meets reinforced insulation requirements under IEC 60747-17, CSA 62368-1 and 60601-1, and CQC GB4943.1. These certifications validate its suitability for safety-critical applications including EV battery management and medical diagnostics where galvanic separation must withstand sustained high voltage stress.
Does the SI86S630BE-IS2 require external startup configuration or initialization firmware?
No, the SI86S630BE-IS2 requires no startup initialization. Its RF-based modulation architecture enables immediate operation after exiting undervoltage lockout (UVLO). Outputs begin tracking inputs within 0.3 ms of VDD1/VDD2 rising above 2.18 V, with no software or hardware setup needed - a key advantage over optocoupler-based or complex digital isolators.
What does the 'E' in SI86S630BE-IS2 signify, and how does it affect system behavior during power loss?
The 'E' suffix in SI86S630BE-IS2 specifies the default-low fail-safe output option. When VDD1 is unpowered (e.g., controller failure), and VDD2 remains active, all B-side outputs (B1–B3) drive low. This behavior is critical in safety systems like motor control or BMS, where a known low state triggers safe shutdown - unlike default-high variants that could inadvertently activate power stages.
Can the SI86S630BE-IS2 operate with mismatched supply voltages on Side A and Side B?
Yes, the SI86S630BE-IS2 supports independent supply rails: VDD1 and VDD2 each operate from 2.25 V to 5.5 V. This allows interfacing a 3.3 V microcontroller (Side A) with a 5 V gate driver or ADC (Side B) without external level shifters - simplifying design and reducing BOM count while maintaining full 150 Mbps data rate and timing specs.
How does the SI86S630BE-IS2 achieve high noise immunity, and what is its CMTI specification?
The SI86S630BE-IS2 achieves high noise immunity through RF on/off keying modulation and Schmitt-trigger inputs with ≥0.15×VDD hysteresis. Its common-mode transient immunity (CMTI) is rated at ≥100 kV/µs minimum - measured per JEDEC JESD22-A114 - ensuring reliable operation in noisy environments such as motor drives and inverters where fast dV/dt transients would disrupt lesser isolators.
