Product details
Overview
SI86S630BE-AS2R from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with 6000 VRMS withstand rating, 150 Mbps data rate, and 10 ns typical propagation delay. It operates across 2.25–5.5 V supplies on both sides and supports fail-safe default-high output mode. Used in isolated ADC interfaces, motor control gate drivers, and battery management system signal conditioning.
For engineers reviewing the SI86S630BE-AS2R datasheet, SI86S630BE-AS2R pinout, SI86S630BE-AS2R application, or SI86S630BE-AS2R equivalent, this page delivers verified specifications, validated pin functions, automotive-grade safety certifications (AEC-Q100, IEC 60747-17), and real-world isolation design context for industrial and EV power systems.
Technical Context
The SI86S630BE-AS2R implements RF-based on-off keying modulation across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity. Its architecture supports independent undervoltage lockout (UVLO) and reset monitoring on both sides (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.
It features tri-state outputs controlled by EN1/EN2 pins, Schmitt-trigger + CMOS input thresholds for high noise rejection, and selectable fail-safe mode (default-high per "E" suffix). Transient immunity exceeds 100 kV/µs, and it meets reinforced insulation requirements per UL 1577, CSA 62368-1/60601-1, and VDE 60747-17.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, CAN FD, and fast feedback loops in inverters. |
| Isolation rating | 6000 VRMS for 1 minute - enables use in 1000 VAC industrial mains and 800 VDC EV battery domains. |
| Propagation delay | 10 ns typical - ensures sub-20 ns round-trip latency for closed-loop motor control timing. |
| 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 temperature | –40 to +125 °C - qualified for under-hood automotive and industrial ambient environments. |
| Fail-safe mode | Default-high output - maintains safe logic state during VDD1 loss in isolated gate driver enable paths. |
| CMTI | >100 kV/µs - prevents false triggering in high-dV/dt SiC/GaN inverter switching nodes. |
Pinout & Package
SI86S630BE-AS2R is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage/clearance), supporting 6000 VRMS reinforced insulation per UL 1577.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides bias for three input-side channels; requires 0.1 µF + 10 µF local bypassing. |
| A1–A3 | Side A digital inputs | CMOS/Schmitt-trigger inputs accepting 2.25–5.5 V logic; tolerate ±0.5 V beyond rails. |
| EN1 | Side A output enable | Active-high control: drives all B1–B3 outputs into high-impedance when low. |
| VDD2, GND2 | Side B power supply | Independent isolated supply domain; supports different voltage than Side A. |
| B1–B3 | Side B digital outputs | 50 Ω nominal output impedance; compatible with 50 Ω PCB traces for signal integrity. |
| EN2 | Side B output enable | Active-high control: places B1–B3 in tri-state; no effect on A-side outputs. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF carrier modulation eliminates boot sequence - outputs follow inputs immediately after UVLO exit (~0.3 ms). |
| Reinforced safety certification | UL 1577 (6000 VRMS), VDE 60747-17, CSA 62368-1/60601-1 - satisfies end-equipment certification for medical and EV traction systems. |
| Tri-state output control | Dual independent EN1/EN2 pins allow selective channel disabling without affecting cross-side operation. |
| High CMTI immunity | 100 kV/µs minimum common-mode transient immunity - sustains reliable operation near SiC half-bridges. |
| Fail-safe default-high | "E" ordering option configures outputs to drive high during VDD1 loss - critical for active-high enable signals in isolated gate drivers. |

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 data rate; 2.5 kVRMS isolation; no AEC-Q100 qualification. | Suitable for cost-sensitive industrial PLC I/O modules where 150 Mbps and automotive qualification are not required. | Choose ADUM3300ARWZ only if lower speed and non-automotive grade are acceptable. |
| ISO6731FDWR | 3-channel, 50 Mbps max data rate; 5000 VRMS; no default-high fail-safe option; TI's capacitive isolation. | Fits factory automation sensors with moderate noise immunity needs but lacks reinforced medical/automotive certifications. | Select ISO6731FDWR when UL/VDE reinforced ratings and fail-safe defaults are not mandatory. |
Compared with ADUM3300ARWZ and ISO6731FDWR, SI86S630BE-AS2R delivers 3× higher bandwidth, 20% higher isolation voltage, AEC-Q100 qualification, and configurable fail-safe behavior-making it uniquely suited for EV powertrain and high-fidelity isolated measurement systems.

FAQ
What is the isolation voltage rating of the SI86S630BE-AS2R and which standards does it meet?
The SI86S630BE-AS2R provides 6000 VRMS reinforced isolation for 1 minute per UL 1577. It is certified to VDE 60747-17 (reinforced), CSA 62368-1 and 60601-1 (medical), and CQC GB4943.1. These approvals validate its use in high-voltage industrial and automotive applications where double insulation is mandated.
Does the SI86S630BE-AS2R require external startup configuration or initialization firmware?
No, the SI86S630BE-AS2R requires no startup initialization. Its RF-based modulation architecture enables immediate operation after exiting UVLO (~0.3 ms after VDD reaches 2.18 V). Outputs begin tracking inputs without software intervention, eliminating boot-time uncertainty in safety-critical systems.
How does the fail-safe default-high mode function in the SI86S630BE-AS2R during power loss?
In the SI86S630BE-AS2R, the "E" suffix denotes default-high fail-safe behavior. When VDD1 drops below UVLO– (1.98 V), outputs B1–B3 transition to and hold a logic high state as long as VDD2 remains powered - ensuring active-enable signals remain asserted during primary-side brownouts.
What are the recommended bypass capacitors for SI86S630BE-AS2R power supplies?
Skyworks specifies a 0.1 µF ceramic capacitor plus a 10 µF bulk capacitor between each VDD–GND pair (VDD1/GND1 and VDD2/GND2). Both must be placed within 5 mm of the respective pins. This dual-capacitor network suppresses high-frequency switching noise and stabilizes supply during fast edge transitions.
Can SI86S630BE-AS2R replace optocouplers in existing designs without layout changes?
Yes - the SI86S630BE-AS2R uses the industry-standard WB SOIC-16 footprint (10.3 mm creepage), matching common optocoupler land patterns. Its 50 Ω output impedance and CMOS-compatible thresholds simplify drop-in replacement, though bypass capacitor placement and ground separation must follow Skyworks' layout guidelines.
