Product details
Overview
SI86S630BC-IS1 from Skyworks Solutions is a 3-channel, reinforced 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, selectable fail-safe mode (default high/low), and operates across –40 to 125 °C in industrial and traction inverter applications.
For engineers reviewing the SI86S630BC-IS1 datasheet, SI86S630BC-IS1 pinout, SI86S630BC-IS1 application, or SI86S630BC-IS1 equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in battery management and onboard chargers, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The SI86S630BC-IS1 implements RF-based on/off keying modulation across a semiconductor isolation barrier-eliminating startup initialization and delivering best-in-class CMTI (>100 kV/µs) and noise immunity. Its dual-supply architecture (VDD1/VDD2 = 2.25–5.5 V) supports independent side-A and side-B operation with UVLO and reset circuitry per side.
It integrates tri-state output control via EN1/EN2 pins, supports fail-safe default states during unpowered conditions, and uses HF XMTR/RCVR blocks per channel for deterministic timing: 10 ns typical propagation delay and 3.5 ns pulse width distortion at 5 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 150 Mbps - supports high-speed SPI, CAN FD interface bridging, and real-time motor control feedback loops. |
| Isolation Rating | 6000 VRMS (1 min) - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for EV traction inverters. |
| Propagation Delay | 10 ns (typ) - enables sub-100 ns loop timing in isolated gate driver feedback paths. |
| Supply Voltage | 2.25–5.5 V per side - interoperable with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| Operating Temp | –40 to 125 °C - qualified for under-hood automotive locations and industrial motor drives. |
| CMTI | ≥100 kV/µs - prevents false triggering in high-dV/dt environments like SiC/GaN power stages. |
| AEC-Q100 | Grade 1 qualified - validated for automotive powertrain and charging systems per stress test requirements. |
Pinout & Package
SI86S630BC-IS1 is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage) with reinforced insulation. Pin layout follows Figure 1 of the datasheet (Si86S63x family), supporting 3 bidirectional channels across an isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides bias for input-side logic and transmitter circuits; requires 0.1 µF + 10 µF local bypass. |
| A1–A3 | Side A digital I/O | Three isolated input/output channels referenced to Side A; compatible with CMOS/Schmitt thresholds. |
| EN1 | Side A output enable | Active-high control: drives all A-side outputs into high-impedance when low - enables bus sharing. |
| Isolation Barrier | Die-level separation | Robust semiconductor barrier rated for 6000 VRMS; defines safety clearance between pins 1–8 and 9–16. |
| B1–B3 | Side B digital I/O | Three isolated output/input channels referenced to Side B; electrically independent from Side A. |
| EN2 | Side B output enable | Active-high control: places all B-side outputs in high-Z state - critical for multi-master isolated buses. |
| VDD2, GND2 | Side B power supply | Independent bias for receiver and output driver circuits; supports split-domain system architectures. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF carrier modulation eliminates boot sequence - output valid within 0.3 ms of VDD stabilization. |
| Selectable fail-safe mode | Ordering option sets default output state (high or low) during VDD1/VDD2 brownout - ensures safe shutdown in BMS. |
| Tri-state outputs with enable | EN1/EN2 pins allow dynamic bus arbitration without external switches - reduces component count in isolated SPI daisy chains. |
| Schmitt + CMOS input thresholds | Combined hysteresis (≥0.15 × VDD) and rail-compatible logic levels reject >36 ns noise pulses - eliminates external filtering. |
| Reinforced IEC 60747-17 rating | Validated barrier withstand capability enables single-package isolation in 800 V EV architectures without additional creepage spacing. |

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, 50 Mbps, 2500 VRMS, SOIC-16, no AEC-Q100 rating | Limited to industrial automation; not qualified for automotive powertrain or charging systems | Choose ADUM3401CRWZ only for cost-sensitive non-automotive designs requiring four channels at lower speed. |
| ISO7731FDWR | 3-channel, 100 Mbps, 5000 VRMS, SOIC-16, AEC-Q100 Grade 2 (–40 to 105 °C) | Lower temperature range and isolation rating - unsuitable for under-hood traction inverter placement | Select ISO7731FDWR for cabin electronics or ADAS domains where 105 °C ambient suffices and 5 kVRMS meets safety plan. |

FAQ
What is the isolation voltage rating of the SI86S630BC-IS1?
The SI86S630BC-IS1 has a reinforced isolation rating of 6000 VRMS for 1 minute per UL 1577, certified to IEC 60747-17. This rating applies to the WB SOIC-16 package and is validated for continuous working voltages up to 1140 V peak in reinforced insulation systems - making it suitable for 800 V EV architectures.
Does the SI86S630BC-IS1 require external startup configuration?
No, the SI86S630BC-IS1 requires no start-up initialization. Its RF-based on/off keying architecture ensures outputs become valid within 0.3 ms after VDD exceeds the UVLO threshold (2.18 V typ). No firmware handshake or register programming is needed - the device is operational immediately upon power stabilization.
How does the fail-safe mode function on the SI86S630BC-IS1?
The SI86S630BC-IS1 offers ordering-option-selectable fail-safe behavior: when VDD1 is unpowered but VDD2 remains active, outputs default to either logic high or logic low based on the specific variant. This behavior is hard-coded in silicon and ensures predictable state during brownout - critical for safe shutdown in battery management systems.
What are the supply voltage requirements for SI86S630BC-IS1 operation?
The SI86S630BC-IS1 operates with independent 2.25–5.5 V supplies on both sides (VDD1 and VDD2). Each side requires local 0.1 µF ceramic + 10 µF bulk capacitance. The device supports mixed-voltage operation - e.g., 3.3 V on Side A and 5 V on Side B - without level-shifting components.
Is the SI86S630BC-IS1 pin-compatible with other Si86S6xx variants?
Yes, the SI86S630BC-IS1 shares identical WB SOIC-16 pinout and footprint with all Si86S63x variants (e.g., SI86S631BC-IS1), including matching A1–A3, B1–B3, EN1, EN2, VDD1/GND1, and VDD2/GND2 assignments. Channel count and fail-safe option differ by part number, but PCB layout is fully reusable across the 3-channel subgroup.
