Product details
Overview
SI86S622BE-IS4 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 and industrial systems. It features Schmitt-trigger + CMOS 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 of control and power domains is critical.
For engineers reviewing the SI86S622BE-IS4 datasheet, SI86S622BE-IS4 pinout, SI86S622BE-IS4 application, or SI86S622BE-IS4 equivalent, key selection criteria include its 10 ns typical propagation delay, 100 kV/µs CMTI, 3.75–6 kVRMS isolation rating options, fail-safe configuration, and SSO-8 automotive-grade package with reinforced IEC 60747-17 certification.
Technical Context
The SI86S622BE-IS4 implements RF-based on/off keying across a semiconductor isolation barrier-replacing legacy optocouplers with superior noise immunity, no start-up initialization, and magnetic field resilience. Its architecture includes independent UVLO and reset circuits per side (VDD1/VDD2), enabling robust operation during asymmetric power sequencing.
It supports fail-safe default-low output behavior via ordering option, integrates input deglitch filters (36 ns), and delivers precise timing with ≤4.5 ns pulse width distortion and ≤3 ns channel-to-channel skew. The device meets reinforced insulation requirements per UL 1577, VDE 60747-17, CSA 62368-1/60601-1, and CQC GB4943.1.

Pinout & Package
SI86S622BE-IS4 uses an SSO-8 (Stretched SOIC-8) package with 8.0 mm creepage and clearance, optimized for reinforced insulation in high-voltage automotive and industrial systems. Pin numbering follows standard SOIC orientation (pin 1 marked).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A Power Supply | Provides 2.25–5.5 V bias for input-side logic and RF transmitter; requires local 0.1 µF + 10 µF bypass capacitors. |
| GND1 | Side A Ground | Reference return path for Side A circuitry; must be isolated from GND2 by ≥8.0 mm PCB spacing. |
| A1, A2 | Side A Digital Inputs | Dual-channel CMOS/Schmitt-trigger inputs with 0.15×VDD hysteresis; accept 0.3×VDD–0.7×VDD logic thresholds. |
| GND2 | Side B Ground | Reference return path for output-side logic and RF receiver; forms isolated domain with VDD2. |
| B1, B2 | Side B Digital Outputs | Push-pull outputs with ~50 Ω impedance; drive 15 pF loads with 2.5 ns rise/fall times; default low during VDD1 undervoltage. |
| VDD2 | Side B Power Supply | Provides 2.25–5.5 V bias for output-side logic and RF receiver; independent of VDD1 for asymmetric supply designs. |
Key Features
| Feature | Design Value |
|---|---|
| RF-Based Isolation Architecture | Eliminates start-up initialization and optical degradation; achieves best-in-class CMTI (100 kV/µs) and magnetic immunity vs. optocouplers. |
| Selectably Fail-Safe Output | Default-low configuration ensures controlled shutdown in BMS and inverter gate drivers when input-side power fails. |

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 | Single 5 V supply only; 150 Mbps; 3.75 kVRMS isolation; SOIC-8 (3.9 mm creepage); no AEC-Q100. | Suitable for industrial 24 V PLC I/O but lacks reinforced insulation and automotive qualification for BEV traction inverters. | Choose ADUM121N0BRZ-RL7 for cost-sensitive, non-automotive 5 V systems requiring same speed but lower isolation rating. |
| ISO7721FDWR | 2.25–5.5 V dual supply; 100 Mbps; 5000 VRMS; SOIC-8 (3.9 mm creepage); AEC-Q100 Grade 1 (–40 to +125 °C). | Meets automotive temp range but offers lower data rate and reduced CMTI (85 kV/µs) vs. SI86S622BE-IS4's 100 kV/µs. | Choose ISO7721FDWR where 100 Mbps suffices and tighter board space allows NB SOIC-8, but avoid where 150 Mbps or highest CMTI is required. |
Compared with ADUM121N0BRZ-RL7 and ISO7721FDWR, SI86S622BE-IS4 uniquely combines 150 Mbps speed, 6000 VRMS reinforced isolation in SSO-8, 100 kV/µs CMTI, and AEC-Q100 Grade 0 qualification-making it the only option validated for high-dV/dt, high-reliability automotive traction applications.

FAQ
What is the isolation voltage rating of SI86S622BE-IS4 and how is it certified?
SI86S622BE-IS4 is rated for 6000 VRMS isolation (1 minute) per UL 1577 and reinforced insulation per VDE 60747-17, CSA 62368-1/60601-1, and CQC GB4943.1. It achieves 1500 VRMS working voltage (VIOWM) in SSO-8 package, validated through TDDB testing and routine production surge screening at 8484 Vpeak. This rating enables use in 800 V battery systems with margin.
Does SI86S622BE-IS4 require external startup initialization or configuration?
No, SI86S622BE-IS4 requires no startup initialization or configuration. Its RF-based architecture enables immediate data transmission upon power-up. Outputs enter a 100 kΩ pulldown state for ≤300 µs during VDD stabilization, then transition to the configured fail-safe state (default low for SI86S622BE-IS4) without firmware or external components.
What is the meaning of "BE" and "IS4" in SI86S622BE-IS4?
In SI86S622BE-IS4, "BE" denotes the default-low fail-safe option and extended temperature range (–40 to +125 °C), while "IS4" specifies the SSO-8 package with reinforced insulation and automotive-grade qualification. This exact ordering code maps to the 6000 VRMS, AEC-Q100 Grade 0, and 36 ns input deglitch filter variant.
How does SI86S622BE-IS4 handle undervoltage conditions on either side?
SI86S622BE-IS4 implements independent UVLO and reset circuits per side. When VDD1 drops below 2.05 V (UVLO–), Side A enters UVLO and outputs go default-low; when VDD1 falls below ~1.7 V (RSTB–), full reset occurs. Side B behaves identically with VDD2. This ensures deterministic behavior during asymmetric brownouts common in automotive power domains.
Can SI86S622BE-IS4 replace optocouplers in existing designs without layout changes?
SI86S622BE-IS4 uses an SSO-8 footprint (7.5 mm × 10.3 mm) with 8.0 mm creepage-larger than standard SOIC-8. Direct replacement requires PCB layout revision to accommodate wider body and increased isolation spacing. However, its pin compatibility with other Si86S6xx devices simplifies migration within Skyworks' family.
