Product details
Overview
SI86S630BE-AS2 from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and 10 ns typical propagation delay. 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 automotive systems such as battery management units and isolated ADC interfaces.
For engineers reviewing the SI86S630BE-AS2 datasheet, SI86S630BE-AS2 pinout, SI86S630BE-AS2 application, or SI86S630BE-AS2 equivalent, key selection criteria include reinforced IEC 60747-17 certification, AEC-Q100 qualification, 2.25–5.5 V dual-supply operation, and precise timing performance for high-noise motor control and power inverter gate drive signal isolation.
Technical Context
The SI86S630BE-AS2 implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity up to 100 kV/µs CMTI. 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 integrates tri-state output control via EN1/EN2 pins, configurable fail-safe default states during unpowered conditions, and supports dual-supply operation with 0.1 µF + 10 µF bypassing per side. The device uses HF XMTR/RCVR circuitry per channel and complies with UL 1577, CSA 62368-1/60601-1, VDE 60747-17, and CQC GB4943.1 safety standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, CAN FD, and real-time control loop signaling without protocol translation. |
| Isolation rating | 6000 VRMS (1 min) - enables use in reinforced insulation applications including onboard chargers and traction inverters per IEC 62368-1. |
| Propagation delay | 10 ns typical - ensures sub-20 ns round-trip latency for time-critical feedback paths in motor control and SMPS. |
| Supply voltage | 2.25–5.5 V per side - allows direct interfacing 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 without derating. |
| CMTI | ≥100 kV/µs - rejects fast transients from IGBT switching in inverters and prevents false triggering in noisy power stages. |
| Safety certifications | UL 1577, VDE 60747-17, CSA 62368-1/60601-1, CQC GB4943.1 - satisfies end-equipment regulatory requirements without additional system-level isolation design. |
Pinout & Package
SI86S630BE-AS2 is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage/clearance) with reinforced insulation. Pin assignments are defined per Figure 1 of the datasheet and validated for this exact part number.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides independent 2.25–5.5 V bias for input-side logic; requires 0.1 µF + 10 µF local decoupling. |
| A1–A3 | Side A digital I/O | Three unidirectional input channels referenced to VDD1/GND1; accept Schmitt-trigger + CMOS thresholds. |
| EN1 | Side A output enable | Active-high control: drives all A-side outputs into high-impedance state when low, enabling bus sharing. |
| Isolation Barrier | Internal RF coupling interface | CMOS-based dielectric barrier supporting 6000 VRMS withstand; no optocoupler aging or LED degradation. |
| B1–B3 | Side B digital I/O | Three unidirectional output channels referenced to VDD2/GND2; support 4 mA sink/source at 0.4 V VOL. |
| EN2 | Side B output enable | Active-high control: places B-side outputs in tri-state, allowing multiple isolators to share an isolated bus. |
| VDD2, GND2 | Side B power supply | Independent 2.25–5.5 V bias for output-side logic; electrically isolated from VDD1/GND1. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot delay - outputs become valid within 0.3 ms of VDD stabilization, critical for fast-restart power systems. |
| Selectable fail-safe mode | Ordering option defines default output state (high or low) during VDD1 loss while VDD2 remains powered - prevents undefined gate drive in BMS fault conditions. |
| Tri-state outputs with enable | EN1/EN2 pins allow dynamic bus contention management on both sides - essential for multi-master isolated SPI or shared serial buses. |
| High electromagnetic immunity | 100 kV/µs common-mode transient immunity (CMTI) - maintains signal integrity in proximity to 100+ A IGBT switching nodes. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 to 125 °C with zero defects in HTOL, TC, and ESD testing - meets OBC and inverter module reliability requirements. |

FAQ
What is the isolation voltage rating of SI86S630BE-AS2 and which safety standards does it meet?
SI86S630BE-AS2 provides 6000 VRMS isolation for 1 minute per UL 1577 and is certified to VDE 60747-17 (reinforced), CSA 62368-1 and 60601-1, and CQC GB4943.1. These approvals validate its use in end-equipment requiring reinforced insulation, including automotive onboard chargers and Class II medical devices. The wide-body SOIC-16 package ensures 10.3 mm creepage and clearance to meet system-level safety requirements without additional board spacing.
Does SI86S630BE-AS2 require startup initialization or configuration before operation?
No, SI86S630BE-AS2 requires no startup initialization. Its RF on/off keying architecture enables immediate operation upon VDD stabilization - outputs become valid within 0.3 ms after VDD rises above the UVLO threshold (2.10–2.25 V). This eliminates boot firmware dependencies and supports fast-restart functionality in uninterruptible power supplies and emergency shutdown circuits.
How does the fail-safe mode function on SI86S630BE-AS2, and how is it selected?
SI86S630BE-AS2 offers factory-selectable fail-safe mode: "B" suffix indicates default-low output, "E" suffix (as in SI86S630BE-AS2) indicates default-high output when VDD1 is unpowered but VDD2 remains active. This behavior is hardwired per ordering code and ensures predictable gate drive or control signal state during primary-side power loss - critical for safe shutdown in battery management systems.
What are the supply voltage and bypass capacitor requirements for SI86S630BE-AS2?
SI86S630BE-AS2 operates from 2.25 V to 5.5 V on both VDD1 and VDD2, with independent grounding (GND1/GND2). Each supply requires a 0.1 µF ceramic capacitor placed adjacent to the pin and a 10 µF bulk capacitor nearby. These values are mandatory per datasheet layout guidance to ensure stable RF modulation and prevent supply-induced jitter or dropout during high-speed data transmission.
Can SI86S630BE-AS2 be used in automotive applications, and what qualifications does it hold?
Yes, SI86S630BE-AS2 is AEC-Q100 Grade 1 qualified (–40 to 125 °C) and built using automotive-specific manufacturing flows. It supports AIAG-compliant PPAP documentation, IMDS/CAMDS reporting, and is approved for use in onboard chargers, battery management systems, charging stations, and traction inverters - meeting functional safety prerequisites for ASIL-B/C system integration.
