Product details
Overview
SI86SL40EE-IS2R from Skyworks Solutions is a 4-channel, low-power digital isolator with reinforced 6000 VRMS isolation, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger inputs, tri-state outputs with enable, selectable fail-safe default (high/low), and operates across –40 to 125 °C in a narrow-body SOIC-16 package. It is used in battery management systems and isolated ADC interfaces where high noise immunity and low quiescent power are critical.
For engineers reviewing the SI86SL40EE-IS2R datasheet, SI86SL40EE-IS2R pinout, SI86SL40EE-IS2R application, or SI86SL40EE-IS2R equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options - all aligned to Skyworks' official Si86S6xx/Lxx family documentation dated August 17, 2023.
Technical Context
The SI86SL40EE-IS2R implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity (100 kV/µs CMTI). Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO– at 1.98 V.
It belongs to the Si86SLx subfamily optimized for low-power operation - consuming 0.25 mA/channel less quiescent current than Si86S6x variants - while retaining identical pinout and core timing specs including 10 ns typical propagation delay and 3.5 ns pulse width distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, QSPI, and serial bus isolation without protocol translation. |
| Isolation rating | 6000 VRMS (1 min) - meets reinforced insulation requirements per UL 1577 and IEC 60747-17 for safety-critical automotive and industrial systems. |
| Propagation delay | 10 ns typical - enables precise timing alignment in motor control gate drivers and isolated feedback loops. |
| Supply voltage | 2.25 to 5.5 V - allows direct interfacing with 3.3 V and 5 V logic domains on both sides of isolation barrier. |
| Operating temperature | –40 to 125 °C - qualified for under-hood automotive applications including onboard chargers and traction inverters. |
| Fail-safe mode | Selectable default output (high or low) during unpowered input - prevents undefined states in BMS fault detection circuits. |
| Transient immunity | ≥100 kV/µs - ensures reliable operation in high-noise environments like power inverters and motor drives. |
Pinout & Package
Narrow-body SOIC-16 (NB SOIC-16) package with 8.0 mm creepage/clearance, RoHS-compliant, and rated for 6000 VRMS isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A supply and ground | Power domain for input-side logic (e.g., MCU GPIO or ADC interface); bypass requires 0.1 µF + 10 µF capacitors. |
| A1–A4 | Side A digital I/O | Four unidirectional input channels; accept CMOS/Schmitt-trigger levels for noise-immune signal reception. |
| VDD2, GND2 | Side B supply and ground | Independent power domain for isolated output side (e.g., gate driver or sensor interface). |
| B1–B4 | Side B digital I/O | Four corresponding output channels; support tri-state via EN1/EN2 pins for bus sharing. |
| EN1, EN2 | Active-high output enable | Single-point control to place all Side A or Side B outputs into high-impedance state - essential for multi-master bus arbitration. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot-time delays - outputs become valid within 0.3 ms of VDD stabilization. |
| Sleep mode option | SMb pin enables <750 µA/side ultra-low-power state while retaining wake-on-input capability - ideal for intermittent telemetry links. |
| High electromagnetic immunity | 100 kV/µs common-mode transient immunity (CMTI) - prevents data corruption in fast-switching SiC/GaN inverter environments. |
| Tri-state outputs with enable | EN1/EN2 pins allow dynamic bus contention avoidance in isolated SPI or parallel control interfaces without external logic. |
| Reinforced safety certification | UL 1577, CSA 62368-1/60601-1, VDE 60747-17, CQC GB4943.1 - enables single-component compliance for medical and EV charging systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8640ED-IS2R | Standard-power variant (Si86S6x) with identical pinout but higher quiescent current (~0.25 mA/channel more). | Better suited for non-battery-constrained industrial PLCs where timing margin is prioritized over power. | Choose when propagation delay consistency across temperature is critical and sleep mode is not required. |
| ADUM140D0BRIZ | 4-channel, 150 Mbps isolator with 3.75 kVRMS rating, 12 ns propagation delay, and no AEC-Q100 qualification. | Limited to industrial automation; not approved for automotive BMS or traction inverter control loops. | Select only for cost-sensitive non-automotive designs where 6000 VRMS and automotive qualification are unnecessary. |
Compared with SI86SL40EE-IS2R, SI8640ED-IS2R trades lower power for slightly better timing stability, while ADUM140D0BRIZ offers comparable speed at reduced isolation strength and no automotive qualification - making SI86SL40EE-IS2R the sole choice for AEC-Q100-compliant, high-isolation, low-power applications.

FAQ
What is the isolation voltage rating of SI86SL40EE-IS2R?
The SI86SL40EE-IS2R provides 6000 VRMS reinforced isolation per UL 1577 for 1 minute, certified to IEC 60747-17, CSA 62368-1/60601-1, and CQC GB4943.1. This rating applies to its narrow-body SOIC-16 package and supports safety-critical applications including EV battery management and medical equipment.
Does SI86SL40EE-IS2R support fail-safe output configuration?
Yes, SI86SL40EE-IS2R includes a selectable fail-safe mode that determines the default output state (high or low) when the input-side supply is unpowered but the output-side supply remains active. This behavior is defined at ordering time and ensures deterministic behavior during brown-out conditions in automotive and industrial systems.
How does the sleep mode function on SI86SL40EE-IS2R?
The SI86SL40EE-IS2R supports sleep mode via the SMb pin: driving SMb low reduces total supply current to <750 µA per side while keeping one channel active to monitor SMb status. When SMb is released (high or floating), the device resumes full operation - enabling ultra-low-power telemetry in battery-powered isolated sensors.
What is the maximum data rate supported by SI86SL40EE-IS2R?
The SI86SL40EE-IS2R supports DC to 150 Mbps data rates across all four channels. This enables high-speed isolation of SPI, QSPI, and custom serial protocols without protocol translation or external clock conditioning - verified under worst-case conditions (–40 to 125 °C, 5.5 V supply).
Is SI86SL40EE-IS2R pin-compatible with other Si86S6xx family members?
Yes, SI86SL40EE-IS2R shares identical NB SOIC-16 pinout and terminal functions with Si86S640xx, Si86S641xx, and Si86S642xx variants. This allows drop-in replacement for low-power optimization without PCB redesign - provided the application does not require direction control (DIR) or SPI-specific pins present in other family members.
