Product details
Overview
SI86S630BC-AS1R 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, and fail-safe default-low output configuration. It is used in isolated ADC/DAC interfaces and motor control gate driver circuits where high CMTI (>100 kV/µs) and AEC-Q100 qualification are required.
For engineers reviewing the SI86S630BC-AS1R datasheet, SI86S630BC-AS1R pinout, SI86S630BC-AS1R application, or SI86S630BC-AS1R equivalent, this page delivers verified specifications, validated pin functions, automotive-grade safety certifications (UL 1577, VDE 60747-17, AEC-Q100), and real-world use context for industrial and EV traction inverter designs.
Technical Context
The SI86S630BC-AS1R implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its dual-supply architecture (VDD1/VDD2 = 2.25–5.5 V) supports independent side-A and side-B operation with separate UVLO and reset thresholds (RSTB– ≈ 1.7 V).
It integrates tri-state enable logic (EN1/EN2), selectable fail-safe mode (default low per -BC suffix), and 100 kΩ weak pulldown on unpowered outputs. The device achieves 3.5 ns pulse width distortion and operates across –40 to 125 °C, meeting reinforced insulation requirements per IEC 60747-17 and CSA 62368-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 150 Mbps - supports high-speed SPI, isolated serial links, and real-time feedback loops in motor drives. |
| Isolation Rating | 6000 VRMS (1 min) - enables reinforced insulation for 1000 VAC working voltage systems per UL 1577. |
| Propagation Delay | 10 ns typical - ensures tight timing alignment between controller and power stage in closed-loop inverters. |
| Pulse Width Distortion | 3.5 ns typical - preserves duty cycle fidelity critical for PWM signal integrity across isolation barrier. |
| CMTI | ≥100 kV/µs - rejects fast transient coupling in high-dV/dt environments like SiC/GaN half-bridges. |
| Supply Voltage | 2.25–5.5 V per side - allows direct interface with 3.3 V microcontrollers and 5 V gate drivers without level shifters. |
| Operating Temp | –40 to 125 °C - qualified for under-hood automotive and industrial ambient conditions. |
Pinout & Package
SI86S630BC-AS1R uses a WB SOIC-16 (wide-body) package with creepage/clearance optimized for 6000 VRMS reinforcement. Pin 1 is marked with dot; pin 16 is VDD2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A supply and ground | Power domain for primary-side logic (e.g., MCU GPIO); bypass requires 0.1 µF + 10 µF capacitors. |
| A1–A3 | Side A digital inputs/outputs | Three bidirectional isolated channels; support CMOS/Schmitt-trigger logic with 0.15×VDD hysteresis. |
| EN1 | Side A output enable | Active-high control: drives A-side outputs into high-impedance state when low - enables bus sharing. |
| VDD2, GND2 | Side B supply and ground | Independent secondary-side power domain (e.g., gate driver IC); supports different voltage than Side A. |
| B1–B3 | Side B digital inputs/outputs | Galvanically isolated mirror of A1–A3; maintains signal integrity across 6000 VRMS barrier. |
| EN2 | Side B output enable | Active-high control for B-side outputs; enables synchronized tri-state control across both sides. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot sequence - outputs follow inputs immediately after UVLO exit. |
| Fail-safe default-low output | BC suffix denotes low-default state during VDD1 undervoltage - prevents unintended gate turn-on in power stages. |
| Tri-state outputs with EN pins | Dual enable inputs (EN1/EN2) allow independent high-Z control per side - essential for shared-bus isolation. |
| High CMTI immunity | ≥100 kV/µs common-mode transient immunity - sustains reliable operation in SiC/GaN inverter switching noise. |
| AEC-Q100 Grade 1 | Qualified for automotive applications up to 125 °C ambient - validated across temperature, humidity, and vibration. |
Applications
| Motor Control Gate Driver Interface | Isolated ADC/DAC Data Link |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3300ARWZ | 3-channel, 25 Mbps max, 2500 VRMS, SOIC-16 (narrow body) | Limited to industrial temp (–40 to 105 °C); no AEC-Q100 or 6000 VRMS rating | Select for cost-sensitive non-automotive systems where 25 Mbps suffices and creepage >8 mm not required. |
| ISO6731FDWR | 3-channel, 50 Mbps max, 5000 VRMS, SOIC-16 (wide body) | Lower CMTI (85 kV/µs); no fail-safe default-low option; TI's reinforced certification differs from VDE 60747-17 | Choose when TI ecosystem integration is prioritized and 50 Mbps bandwidth meets system timing budget. |

FAQ
What is the isolation voltage rating of SI86S630BC-AS1R?
SI86S630BC-AS1R is rated for 6000 VRMS isolation per UL 1577 for 1 minute, with reinforced insulation certified to VDE 60747-17 and CSA 62368-1. This enables use in 1000 VAC working voltage systems and meets requirements for EV traction inverters and industrial motor drives.
Does SI86S630BC-AS1R require external startup initialization?
No, SI86S630BC-AS1R requires no startup initialization due to its RF-based on/off keying architecture. Outputs begin tracking inputs within 0.3 ms after VDD exceeds UVLO+ (2.18 V), with 100 kΩ weak pulldown holding outputs low until stabilization - eliminating boot firmware dependencies.
What does the "BC" suffix indicate in SI86S630BC-AS1R?
The "BC" suffix in SI86S630BC-AS1R specifies the fail-safe operating mode: default-low output state when Side A supply (VDD1) is unpowered but Side B (VDD2) remains active. This prevents unintended activation of downstream power devices during brownout conditions.
Can SI86S630BC-AS1R operate with different supply voltages on each side?
Yes, SI86S630BC-AS1R supports independent 2.25–5.5 V supplies on Side A (VDD1) and Side B (VDD2). This allows interfacing a 3.3 V MCU with a 5 V gate driver IC without external level shifters, while maintaining full isolation integrity and timing performance.
Is SI86S630BC-AS1R qualified for automotive applications?
Yes, SI86S630BC-AS1R is AEC-Q100 Grade 1 qualified (–40 to 125 °C), with AIAG-compliant PPAP documentation, IMDS/CAMDS listings, and manufacturing flows specific to automotive robustness - making it suitable for onboard chargers, battery management systems, and traction inverters.
