Product details
Overview
SI86S630BC-AS1 from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with bidirectional signal transfer across an RF-based semiconductor barrier. It delivers DC–150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating in a WB SOIC-16 package. It operates from 2.25–5.5 V supplies and supports fail-safe default-high output mode for industrial motor control and isolated ADC interfaces.
For engineers reviewing the SI86S630BC-AS1 datasheet, SI86S630BC-AS1 pinout, SI86S630BC-AS1 application, or SI86S630BC-AS1 equivalent, key selection criteria include its AEC-Q100 qualification, IEC 60747-17 reinforced insulation, tri-state outputs with EN1/EN2 control, Schmitt-trigger + CMOS input thresholds, and 100 kV/µs CMTI performance - all validated for automotive onboard chargers and battery management systems.
Technical Context
The SI86S630BC-AS1 implements RF on/off keying modulation across a monolithic semiconductor isolation barrier, eliminating startup initialization and enabling deterministic timing without clock recovery circuits. Its architecture integrates independent undervoltage lockout (UVLO) and reset monitors per side (VDD1/VDD2), with RSTB– threshold at ~1.7 V and UVLO– at 1.98 V.
It features side-specific enable inputs (EN1 on Side A, EN2 on Side B) that place corresponding outputs into high-impedance state, plus selectable fail-safe mode (default-high for this variant). All channels support Schmitt-trigger inputs with 0.15×VDD hysteresis and CMOS-compatible thresholds (VIH = 0.7×VDD, VIL = 0.3×VDD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, isolated UART, and real-time control loop signaling without oversampling. |
| Propagation delay | 10 ns typical - enables sub-100 ns round-trip latency in closed-loop isolated feedback paths. |
| Isolation rating | 6000 VRMS (1 min) - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for >1000 VAC working voltage systems. |
| Supply voltage | 2.25–5.5 V per side - allows interoperability with 3.3 V and 5 V logic domains without level shifters. |
| CMTI | ≥100 kV/µs - ensures robust operation in high-dV/dt environments like motor drives and inverters. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions. |
| Fail-safe mode | Default-high output - maintains known logic state during VDD1 loss while VDD2 remains powered. |
Pinout & Package
SI86S630BC-AS1 is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance ≥8.3 mm, supporting 6000 VRMS isolation. Pin 1 is marked with a dot; pin numbering follows standard SOIC convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A supply | 2.25–5.5 V power for input-side circuitry; requires 0.1 µF + 10 µF bypass capacitors. |
| GND1 | Side A ground | Reference return for VDD1 and A1–A3 signals; must be separated from GND2 by isolation barrier. |
| A1–A3 | Side A digital I/O | Three unidirectional/bidirectional data channels; Schmitt-trigger + CMOS input thresholds. |
| EN1 | Side A output enable | Active-high control: drives A1–A3 outputs to high-impedance when low. |
| Isolation Barrier | Internal RF barrier | Semiconductor-based dielectric barrier separating Side A and Side B; no external components required. |
| B1–B3 | Side B digital I/O | Three isolated output channels; default-high fail-safe behavior active when VDD1 is unpowered. |
| EN2 | Side B output enable | Active-high control: drives B1–B3 outputs to high-impedance when low. |
| GND2 | Side B ground | Reference return for VDD2 and B1–B3 signals; galvanically isolated from GND1. |
| VDD2 | Side B supply | 2.25–5.5 V power for output-side circuitry; independent of VDD1 for dual-supply operation. |
Key Features
| Feature | Design Value |
|---|---|
| No-startup initialization | RF modulation architecture eliminates boot sequence - outputs follow inputs immediately after UVLO exit. |
| Tri-state output control | Dedicated EN1/EN2 pins allow single-point disable of all Side A or Side B outputs without affecting isolation integrity. |
| Reinforced safety certification | UL 1577 (6000 VRMS), VDE 60747-17, CSA 62368-1/60601-1 - enables use in medical and EV traction systems without additional system-level barriers. |
| High-noise immunity inputs | Schmitt-trigger + CMOS thresholds with 0.15×VDD hysteresis reject <36 ns glitches and tolerate >100 kV/µs common-mode transients. |
| Automotive-grade reliability | AEC-Q100 Grade 1 qualification, PPAP documentation support, and IMDS/CAMDS compliance for OEM automotive supply chains. |

FAQ
What is the isolation voltage rating of SI86S630BC-AS1 and which standards does it meet?
SI86S630BC-AS1 provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to IEC 60747-17 (reinforced insulation), CSA 62368-1/60601-1, and CQC GB4943.1. This rating applies to the WB SOIC-16 package and supports working voltages up to 1000 VAC in end equipment meeting IEC 61010-1 or IEC 62368-1 requirements.
Does SI86S630BC-AS1 require external components for basic operation?
SI86S630BC-AS1 requires only two bypass capacitors per side: 0.1 µF ceramic and 10 µF bulk capacitor placed between VDD1/GND1 and VDD2/GND2. No external resistors, level shifters, or initialization firmware are needed - the device begins passing signals immediately after VDD exceeds UVLO+ (2.18 V typical).
How does the fail-safe mode function on SI86S630BC-AS1?
SI86S630BC-AS1 is ordered with default-high fail-safe mode, meaning when VDD1 is unpowered (<2.25 V) but VDD2 remains active, all B1–B3 outputs drive logic high. This behavior is hard-coded per ordering option and ensures predictable state during controller-side brownout - critical for safety interlocks in motor drives and BMS.
What is the maximum data rate supported by SI86S630BC-AS1 and how is timing performance characterized?
SI86S630BC-AS1 supports DC to 150 Mbps data rate. Its timing is characterized with 10 ns typical propagation delay, 3.5 ns typical pulse width distortion, and <1 ns channel-to-channel skew. These values are measured at 5 V supply, 25 °C, with 15 pF load and 500 kHz square-wave input per channel.
Is SI86S630BC-AS1 suitable for automotive applications and what qualifications does it hold?
Yes, SI86S630BC-AS1 is AEC-Q100 Grade 1 qualified (–40 °C to +125 °C), with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and full support for automotive production flow requirements. It is explicitly listed for onboard chargers, battery management systems, and traction inverters in Skyworks' application guidance.
