Product details
Overview
SI86SL41EE-AS2 from Skyworks Solutions is a 4-channel, low-power digital isolator with reinforced 6000 VRMS isolation, designed for bidirectional signal transmission across high-voltage barriers in automotive and industrial systems. It operates from 2.25 to 5.5 V, delivers ≤10 ns propagation delay, supports up to 150 Mbps data rate, and features selectable fail-safe output (default-low), AEC-Q100 qualification, and –40 to 125 °C operation.
For engineers reviewing the SI86SL41EE-AS2 datasheet, SI86SL41EE-AS2 pinout, SI86SL41EE-AS2 application, or SI86SL41EE-AS2 equivalent, this device is evaluated for isolated SPI interfaces, motor control gate drivers, battery management system communication links, and high-noise industrial PLC I/O modules requiring precise timing and robust CMTI immunity.
Technical Context
The SI86SL41EE-AS2 implements RF-based on/off keying modulation across a semiconductor isolation barrier-eliminating startup initialization and providing superior noise immunity over optical or capacitive alternatives. Its architecture includes Schmitt-trigger inputs, CMOS thresholds, and tri-state outputs controlled by side-specific enable pins (EN1/EN2).
This variant belongs to the Si86SLx low-power subfamily: it consumes ~0.25 mA per channel less quiescent current than Si86S6x counterparts while maintaining identical pinout and reinforced 6000 VRMS isolation rating. Fail-safe default-low behavior is fixed by ordering code "EE", and sleep mode is not implemented in this part.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | Up to 150 Mbps - supports high-speed serial protocols including SPI and isolated UART without oversampling or clock recovery circuitry. |
| Propagation delay | 10 ns typical - enables tight timing budgets in real-time control loops such as motor phase commutation or ADC sampling synchronization. |
| Isolation rating | 6000 VRMS - meets reinforced insulation requirements per UL 1577, VDE 60747-17, and CSA 62368-1 for safety-critical automotive and medical applications. |
| Supply voltage | 2.25–5.5 V - allows direct interfacing with 3.3 V and 5 V logic domains without level-shifting components. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive use and industrial environments with wide thermal cycling. |
| CMTI | ≥100 kV/µs - rejects fast transient common-mode noise from power switches, ensuring reliable operation in inverters and SMPS. |
| AEC-Q100 grade | Grade 1 - validated for automotive electronics with full PPAP documentation support and IMDS/CAMDS compliance. |
Pinout & Package
SI86SL41EE-AS2 is housed in a narrow-body SOIC-16 package (NB SOIC-16) with 8.0 mm creepage/clearance, optimized for space-constrained PCB layouts while maintaining 6000 VRMS isolation integrity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Side A input/output (A1–A4) | Four bidirectional digital channels on main side; compatible with CMOS/Schmitt-trigger logic levels and support tri-state via EN1. |
| 5 | EN1 | Active-high enable controlling all Side A outputs; drives outputs into high-impedance state when low. |
| 6, 7, 8, 9 | Side B input/output (B1–B4) | Four isolated bidirectional digital channels on secondary side; electrically separated from Side A by reinforced barrier. |
| 10 | EN2 | Active-high enable controlling all Side B outputs; independent of EN1 for asymmetric enable control. |
| 11, 16 | GND1, GND2 | Separate ground references for each side - mandatory for maintaining galvanic isolation integrity and noise rejection. |
| 12, 15 | VDD1, VDD2 | Independent 2.25–5.5 V supplies for each side - enables level translation and fault containment between domains. |
| 13, 14 | NC | No-connect pins - must remain unconnected per design; no internal bonding or function. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced 6000 VRMS isolation | UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1 certified - eliminates need for external isolation components in safety-rated systems. |
| Fail-safe default-low output | Fixed by "EE" ordering option - ensures predictable low-state outputs during power loss or undervoltage, critical for safe shutdown in motor drives. |
| Low-power Si86SLx architecture | ~0.25 mA/channel lower quiescent current vs. Si86S6x - reduces thermal load and extends battery life in always-on automotive modules. |
| 100 kV/µs CMTI | Immunity to fast common-mode transients from IGBT/MOSFET switching - prevents data corruption in high-dV/dt environments like traction inverters. |
| No start-up initialization | RF modulation architecture enables immediate data transmission at power-on - eliminates boot delay and simplifies firmware design. |
| Schmitt-trigger + CMOS inputs | High noise margin (>15% VDD hysteresis) and compatibility with standard logic families - reduces susceptibility to EMI in noisy industrial settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8641ED-AS2 | Same pinout, 4-channel, 6000 VRMS, but higher quiescent current (Si86S6x family); default-high fail-safe (ED suffix). | Preferred where fail-safe high output is required for active-low reset signaling or pull-up dependent logic. | Select SI8641ED-AS2 only if default-high behavior is needed; otherwise SI86SL41EE-AS2 offers lower power consumption. |
| ADUM140D0BRZ | 4-channel, 5000 VRMS (not reinforced), 100 Mbps max, 15 ns propagation delay, non-AEC-Q100. | Suitable for industrial automation but not automotive or medical safety-critical systems requiring reinforced insulation. | Choose ADUM140D0BRZ only for cost-sensitive non-automotive designs where 5000 VRMS suffices and AEC-Q100 is not mandated. |
Compared with SI8641ED-AS2, SI86SL41EE-AS2 reduces quiescent power by ~0.25 mA/channel and guarantees fail-safe low output, making it optimal for battery-powered automotive modules; versus ADUM140D0BRZ, it provides higher isolation rating, faster timing, and automotive qualification - essential for traction inverter and BMS applications.

FAQ
What is the isolation voltage rating of the SI86SL41EE-AS2?
The SI86SL41EE-AS2 provides reinforced 6000 VRMS isolation per UL 1577 for 1 minute, certified to VDE 60747-17, CSA 62368-1, and CQC GB4943.1. This rating applies to the NB SOIC-16 package and enables use in high-voltage safety-critical applications such as automotive traction inverters and medical power supplies where reinforced insulation is mandated.
Does the SI86SL41EE-AS2 support SPI isolation?
Yes, the SI86SL41EE-AS2 supports SPI isolation through its four bidirectional channels: A1–A4 and B1–B4 can be assigned to MOSI, MISO, SCLK, and CSb signals. While not a dedicated SPI isolator like Si86SS41, its pin-compatible layout and fail-safe default-low behavior make it suitable for custom SPI implementations requiring galvanic separation and deterministic power-loss response.
What does the "EE" suffix indicate in SI86SL41EE-AS2?
The "EE" suffix in SI86SL41EE-AS2 specifies the fail-safe output configuration: default-low behavior during unpowered or undervoltage conditions on the input side. This is a factory-set ordering option - not user-configurable - and ensures outputs drive low when VDD1 falls below UVLO threshold, critical for safe shutdown in motor control and BMS applications.
Is the SI86SL41EE-AS2 pin-compatible with other Si86Sxx devices?
Yes, SI86SL41EE-AS2 shares identical NB SOIC-16 pinout with Si86S64x, Si86L4x, and Si86M4x 4-channel variants. Pin functions (A1–A4, B1–B4, EN1, EN2, VDD1/VDD2, GND1/GND2, NC) are fully aligned, enabling drop-in replacement where low-power operation and default-low fail-safe are acceptable trade-offs for reduced quiescent current.
What is the maximum data rate supported by SI86SL41EE-AS2?
The SI86SL41EE-AS2 supports data rates up to 150 Mbps across all four channels. This capability is verified under worst-case conditions (TA = 125 °C, VDD = 2.25 V) and enables high-speed serial protocols including isolated SPI, CAN FD physical layer signaling, and real-time sensor data streaming in automotive and industrial edge nodes.
