Product details
Overview
SI86S630EC-AS1 from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger + CMOS inputs, tri-state outputs with enable, and selectable fail-safe mode (default high/low) for power-loss scenarios in battery management and traction inverters.
For engineers reviewing the SI86S630EC-AS1 datasheet, SI86S630EC-AS1 pinout, SI86S630EC-AS1 application, or SI86S630EC-AS1 equivalent, this device delivers precise timing (10 ns propagation delay), high CMTI (>100 kV/µs), and dual-supply operation (2.25–5.5 V) across isolated domains - critical for functional safety in onboard chargers and isolated ADC interfaces.
Technical Context
The SI86S630EC-AS1 implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture supports independent UVLO monitoring per side (VDD1/VDD2), with RSTB reset thresholds at ~1.7 V and tSTART of 0.3 ms.
It integrates tri-state output control via EN1/EN2 pins, selectable fail-safe default state (high/low), and operates across –40 to 125 °C with reinforced IEC 60747-17 insulation. The device uses HF XMTR/RCVR circuitry per channel and requires only 0.1 µF + 10 µF bypass capacitors per supply rail.
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 |
|---|---|---|---|
| ADUM3401CRWZ | 4-channel, 100 Mbps, 2.5–5.5 V, 3750 VRMS, non-AEC-Q100 | Lacks automotive qualification and 6000 VRMS rating; suitable for industrial but not traction inverter BOMs. | Choose when cost sensitivity outweighs automotive compliance and higher isolation voltage. |
| ISO7731FDWR | 3-channel, 100 Mbps, 2.25–5.5 V, 5000 VRMS, AEC-Q100 Grade 1 | Lower isolation rating (5000 vs. 6000 VRMS); no selectable fail-safe mode; same pin count but different pinout. | Prefer for legacy TI-based designs where layout reuse is prioritized over maximum isolation margin. |
Compared with ADUM3401CRWZ and ISO7731FDWR, SI86S630EC-AS1 uniquely combines AEC-Q100 Grade 1, 6000 VRMS, 150 Mbps, and configurable fail-safe output - making it the only drop-in solution for next-gen EV powertrain control requiring reinforced insulation and functional safety alignment.

FAQ
What is the isolation voltage rating of SI86S630EC-AS1 and which safety standards does it meet?
The SI86S630EC-AS1 has a 6000 VRMS isolation rating 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 specifically to the WB SOIC-16 package variant and enables use in 800 V battery systems without additional creepage/clearance reinforcement.
Does SI86S630EC-AS1 support fail-safe output configuration, and how is it implemented?
Yes, SI86S630EC-AS1 offers selectable fail-safe mode (default high or low) via ordering option - the EC suffix indicates default-high behavior. When VDD1 or VDD2 drops below UVLO threshold, outputs transition to the pre-configured state within 0.3 ms, ensuring safe shutdown in BMS and inverter applications.
What are the supply voltage requirements for SI86S630EC-AS1, and can Side A and Side B operate at different voltages?
SI86S630EC-AS1 supports independent 2.25–5.5 V supplies on VDD1 and VDD2, allowing Side A to run at 3.3 V while Side B operates at 5 V. This flexibility enables direct interfacing with mixed-voltage systems such as 3.3 V MCUs and 5 V analog front-ends without level shifters.
How does the RF-based isolation architecture of SI86S630EC-AS1 differ from optocoupler-based isolators?
SI86S630EC-AS1 uses RF on/off keying across a silicon dioxide isolation barrier instead of LED-photodiode coupling. This eliminates LED aging, provides stable 10 ns propagation delay across temperature, and achieves >100 kV/µs CMTI - outperforming optocouplers in lifetime, speed, and noise immunity for automotive power electronics.
Is SI86S630EC-AS1 pin-compatible with other devices in the Si86S6xx family, such as SI86S631EC-AS1?
Yes, SI86S630EC-AS1 and SI86S631EC-AS1 share identical WB SOIC-16 pinout and footprint. The only functional difference is channel directionality: SI86S630EC-AS1 has three unidirectional channels (A→B), while SI86S631EC-AS1 has two forward and one reverse channel - both are drop-in replacements for layout purposes.
