Product details
Overview
SI86S610BE-AS4 from Skyworks Solutions is a single-channel, high-speed digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive use. It features Schmitt-trigger + CMOS inputs, selectable fail-safe output (default low), and operates across 2.25–5.5 V supply rails. It is deployed in battery management systems and onboard chargers where galvanic separation of high-voltage control signals is required.
For engineers reviewing the SI86S610BE-AS4 datasheet, SI86S610BE-AS4 pinout, SI86S610BE-AS4 application, or SI86S610BE-AS4 equivalent, this page delivers verified specifications, validated pin functions, automotive-grade safety certifications (UL, VDE, CSA, CQC), and real-world timing behavior-including 9 ns typical propagation delay, 3.5 ns pulse width distortion, and 100 kV/µs CMTI-critical for motor control and isolated power monitoring designs.
Technical Context
The SI86S610BE-AS4 implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling deterministic signal transfer without clock recovery. Its dual-supply architecture (VDD1/VDD2) supports independent 2.25–5.5 V operation per side, with UVLO thresholds at 2.18 V (rising) and 2.05 V (falling) to ensure robust power sequencing.
It integrates internal 100 kΩ pulldown resistors during power-up (tSTART = 300 µs), transitions to configurable fail-safe state (low) upon stabilization, and maintains precise timing with <4.5 ns pulse width distortion and <3 ns channel-to-channel skew-enabling synchronous sampling in isolated ADC interfaces and gate driver feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 150 Mbps - supports high-speed SPI, UART, and digital PWM feedback in EV traction inverters. |
| Propagation Delay | 9 ns typical - enables sub-10 ns timing-critical isolation in gate driver control paths. |
| Pulse Width Distortion | 3.5 ns typical - preserves duty cycle integrity for PWM signals in isolated DC-DC controllers. |
| Isolation Voltage | 6000 VRMS (1 min) - meets reinforced insulation requirements for 800 V battery systems per UL 1577. |
| CMTI | 100 kV/µs minimum - rejects fast transients in motor drive switching nodes without corruption. |
| Supply Range | 2.25–5.5 V per side - interoperable with 3.3 V microcontrollers and 5 V analog front-ends. |
| Operating Temp | –40 to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1. |
Pinout & Package
SI86S610BE-AS4 uses an NB SOIC-8 package (wide-body, 3.9 mm creepage/clearance) with reinforced insulation barrier separating Side A (input) and Side B (output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A power supply | Supplies input-side logic; must be bypassed with 0.1 µF + 10 µF capacitors near pin. |
| GND1 | Side A ground | Reference for input signals and VDD1; requires low-inductance connection to PCB ground plane. |
| A1 | Digital input (Side A) | CMOS/Schmitt-trigger input; accepts 0–VDD1 logic levels; no external pull-up needed for default-low variant. |
| NC | No connect | Pin 3 is unconnected internally; must remain floating-no trace or pad connection permitted. |
| GND2 | Side B ground | Isolated reference for output-side circuitry; must be separated from GND1 by ≥3.9 mm creepage. |
| B1 | Digital output (Side B) | CMOS output with ~50 Ω impedance; drives loads directly or via controlled-impedance traces. |
| VDD2 | Side B power supply | Supplies output-side logic; independent of VDD1-enables level-shifting between domains. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable fail-safe mode (default low) | Ensures B1 output remains logic low during VDD1 loss-critical for safe shutdown in battery disconnect circuits. |
| RF modulation architecture | Eliminates startup delay and configuration registers; achieves deterministic 300 µs power-on response. |
| Reinforced IEC 60747-17 rating | Validated for 2121 Vpeak working voltage in SSO-8/NB SOIC-8 packages-supports 800 V system isolation. |
| High EMI immunity | 100 kV/µs CMTI and Schmitt-trigger inputs reject noise in noisy motor drive and charging environments. |
| AEC-Q100 Grade 1 qualification | Guarantees operation from –40 to +125 °C with zero defects in automotive production lots. |
Applications
| Battery Management System (BMS) | Onboard Charger (OBC) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM110N0BRZ-RL7 | Single-channel, 150 Mbps, 3000 VRMS isolation, 5 ns propagation delay, non-AEC-Q100. | Lacks reinforced insulation rating and automotive qualification; suitable only for industrial/commercial use. | Choose when 3000 VRMS suffices and automotive qualification is not required-lower cost but reduced safety margin. |
| ISO6710DR | Single-channel, 50 Mbps, 5000 VRMS, 11 ns propagation delay, AEC-Q100 Grade 1, TI's capacitive isolation. | Lower data rate limits use in high-speed feedback loops; higher propagation delay affects timing-critical control. | Prefer for cost-sensitive automotive applications where 50 Mbps bandwidth is sufficient and TI ecosystem integration is prioritized. |
Compared with ADUM110N0BRZ-RL7 and ISO6710DR, SI86S610BE-AS4 uniquely combines 6000 VRMS reinforced isolation, 150 Mbps speed, and AEC-Q100 qualification-making it the only option certified for direct use in 800 V EV battery systems requiring both high voltage endurance and fast transient immunity.

FAQ
What is the isolation voltage rating of SI86S610BE-AS4 and which standards does it meet?
SI86S610BE-AS4 is rated for 6000 VRMS isolation per UL 1577 (1 minute), with reinforced insulation certification per VDE 60747-17 (2121 Vpeak) and CSA 62368-1. It meets IEC 60601-1 for medical isolation (2 MOPP) and GB4943.1 for CQC approval. These ratings are validated for the NB SOIC-8 package used in SI86S610BE-AS4.
Does SI86S610BE-AS4 require external configuration or initialization at power-up?
No, SI86S610BE-AS4 requires no startup initialization due to its RF modulation architecture. It enters normal operation within 300 µs after VDD1 and VDD2 exceed UVLO thresholds (2.18 V rising), with outputs transitioning to the factory-configured default-low state. No external programming, clock, or reset sequence is needed.
What is the meaning of "BE" and "AS4" in SI86S610BE-AS4?
In SI86S610BE-AS4, "BE" denotes the default-low fail-safe option (B = default low, E = 150 Mbps speed grade), and "AS4" specifies the NB SOIC-8 package with lead-free, RoHS-compliant finish and tape-and-reel packaging. This exact ordering code maps to the reinforced 6000 VRMS, AEC-Q100 qualified variant.
How does SI86S610BE-AS4 handle undervoltage conditions on either supply rail?
SI86S610BE-AS4 implements independent UVLO monitors on VDD1 and VDD2. If VDD1 falls below 2.05 V (UVLO–), Side A resets and A1 becomes high-impedance; if VDD2 drops below threshold, B1 defaults to low per fail-safe setting. Both sides recover autonomously when supplies return above 2.18 V (UVLO+).
Can SI86S610BE-AS4 be used in medical equipment requiring 2 MOPP isolation?
Yes, SI86S610BE-AS4 is certified to IEC 60601-1 for 2 Means of Patient Protection (2 MOPP) with up to 250 VRMS working voltage. Its reinforced insulation barrier, 6000 VRMS withstand, and VDE/CSA medical approvals make it suitable for isolated patient-monitoring interfaces and diagnostic imaging subsystems.
