Product details
Overview
SI86S620BE-AS4R from Skyworks Solutions is a dual-channel, high-speed digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger inputs, selectable fail-safe output (default low), and operates across 2.25–5.5 V supply rails. Used in battery management systems and traction inverters where galvanic separation and noise immunity are critical.
For engineers reviewing the SI86S620BE-AS4R datasheet, SI86S620BE-AS4R pinout, SI86S620BE-AS4R application, or SI86S620BE-AS4R equivalent, this page delivers verified electrical specs, isolation barrier behavior, fail-safe mode configuration, and automotive-grade safety certification details required for functional safety-compliant designs.
Technical Context
The SI86S620BE-AS4R implements RF-based on/off keying across a semiconductor isolation barrier-no start-up initialization required. Its dual-channel architecture supports independent side-A and side-B power domains (VDD1/GND1 and VDD2/GND2), each with undervoltage lockout (UVLO+ = 2.18 V, UVLO– = 2.05 V) and reset thresholds (RSTB+ ≈ 1.7 V).
It integrates input deglitch filters (36 ns), achieves 10 ns typical propagation delay, and delivers 100 kV/µs common-mode transient immunity (CMTI). The device uses CMOS thresholds with 0.15×VDD input hysteresis and supports fail-safe operation via ordering option (default low output during input-side power loss).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps - enables high-bandwidth serial communication (e.g., SPI, CAN FD isolation) without timing bottlenecks. |
| Propagation delay | 5–14 ns (typ. 10 ns) - ensures tight timing alignment in motor control gate drivers and ADC sampling clocks. |
| Isolation rating | 6000 VRMS (1 min) - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for 1500 VRMS working voltage. |
| Supply voltage | 2.25–5.5 V - supports direct interface with 3.3 V and 5 V logic domains without level-shifting circuitry. |
| Operating temperature | –40 to +125 °C - qualified for under-hood automotive applications including onboard chargers and BMS. |
| CMTI | 100 kV/µs - rejects fast transients in high-noise environments like power inverters and motor drives. |
| Fail-safe mode | Default low output - ensures safe shutdown state when side-A supply fails, critical for fault-tolerant control loops. |
Pinout & Package
SI86S620BE-AS4R is housed in an NB SOIC-8 package (3.9 mm creepage/clearance) with 8-pin layout optimized for reinforced isolation. Pin 1 (VDD1) and pin 8 (VDD2) are isolated power supplies; pins 2–3 (A1–A2) and 6–7 (B1–B2) are bidirectional data channels; pin 4 (NC) must remain unconnected; pins 5 (GND2) and 1 (GND1) serve as isolated ground references.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side-A power supply | Provides bias for input-side transmitter; requires 0.1 µF + 10 µF bypass capacitors near pin. |
| GND1 | Side-A ground reference | Return path for VDD1; must be physically separated from GND2 by ≥3.9 mm creepage. |
| A1, A2 | Side-A digital I/O | Accepts Schmitt-trigger inputs with 0.15×VDD hysteresis; compatible with 3.3 V/5 V logic. |
| NC | No-connect terminal | Internally unused; must be left floating-no PCB trace or solder connection permitted. |
| GND2 | Side-B ground reference | Return path for VDD2; forms isolated domain with VDD2 and B1/B2 outputs. |
| B1, B2 | Side-B digital I/O | CMOS outputs with ~50 Ω impedance; drive 15 pF loads directly; support fail-safe default-low state. |
| VDD2 | Side-B power supply | Biases output-side receiver; independent of VDD1-enables asymmetric supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates optical degradation and startup delays-guarantees deterministic operation from first power-on. |
| Selectably fail-safe output | Ordering code "BE" specifies default-low behavior, ensuring controlled deactivation during side-A brownout. |
| Input deglitch filter (36 ns) | Rejects sub-36 ns noise pulses-prevents false triggering in EMI-heavy industrial motor control environments. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient-supports PPAP documentation and IMDS/CAMDS compliance. |
| Reinforced insulation certification | UL 1577 (6000 VRMS), VDE 60747-17, CSA 62368-1, CQC GB4943.1-enables single-component safety approval in end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM121N0BRZ-RL7 | 5000 VRMS isolation, 150 Mbps, default-high fail-safe, SOIC-8 (3.9 mm clearance) | Lacks AEC-Q100 qualification; not certified to IEC 60747-17 reinforced insulation | Use only in non-automotive industrial applications where 5000 VRMS suffices and default-high behavior aligns with system logic. |
| ISO7721FDWR | 5000 VRMS, 100 Mbps, default-low fail-safe, SOIC-16 (8.0 mm clearance), 2.25–5.5 V | Lower data rate limits CAN FD and high-speed SPI; wider SOIC-16 footprint increases PCB area | Prefer when higher creepage (>6 mm) is mandated by end-equipment standards, and 100 Mbps meets bandwidth needs. |

FAQ
What is the isolation voltage rating of SI86S620BE-AS4R and which safety standards does it meet?
SI86S620BE-AS4R is rated for 6000 VRMS isolation per UL 1577 (1 minute), with reinforced insulation certification to VDE 60747-17, CSA 62368-1, and CQC GB4943.1. It supports 1500 VRMS working voltage and 2121 Vpeak repetitive voltage in SSO-8/NB SOIC-8 packages-validated for automotive and medical end-equipment safety approvals.
Does SI86S620BE-AS4R require external start-up initialization or configuration?
No-SI86S620BE-AS4R requires no start-up initialization. It begins transmitting valid data within 300 µs of power application due to its RF-based modulation architecture. UVLO and reset circuits operate autonomously, and the default-low fail-safe state is hardwired per ordering code "BE", eliminating firmware dependencies.
How does the fail-safe mode function in SI86S620BE-AS4R during input-side power loss?
In SI86S620BE-AS4R, the "BE" suffix denotes default-low fail-safe mode. When VDD1 drops below UVLO– (2.05 V), outputs B1 and B2 transition to logic low within 12 ns (tSD), regardless of input state. This ensures safe shutdown of downstream gate drivers or control logic during side-A brownout events.
What is the maximum data rate supported by SI86S620BE-AS4R and what timing parameters enable it?
SI86S620BE-AS4R supports up to 150 Mbps data rate, enabled by 5–14 ns propagation delay (typ. 10 ns), ≤4.5 ns pulse width distortion, and 350 ps peak eye diagram jitter. These values are guaranteed across –40 to +125 °C and 2.25–5.5 V supply range, making it suitable for high-speed SPI, RS-485, and CAN FD isolation.
Can SI86S620BE-AS4R operate with mismatched supply voltages on side-A and side-B?
Yes-SI86S620BE-AS4R supports independent VDD1 and VDD2 supplies ranging from 2.25 V to 5.5 V each. Side-A and side-B can operate at different voltages (e.g., 3.3 V on side-A, 5 V on side-B) without performance degradation, enabling seamless interface between mixed-voltage subsystems in automotive ECUs and industrial controllers.
