Product details
Overview
SI86S663EE-IS2R from Skyworks Solutions is a 6-channel reinforced digital isolator with 6000 VRMS isolation, 150 Mbps data rate, 10 ns propagation delay, and AEC-Q100 qualification for automotive systems. It features dual-side enable (EN1/EN2), Schmitt-trigger inputs, CMOS thresholds, and operates across 2.25–5.5 V supply rails in –40 to +125 °C ambient.
For engineers reviewing the SI86S663EE-IS2R datasheet, SI86S663EE-IS2R pinout, SI86S663EE-IS2R application, or SI86S663EE-IS2R equivalent, key selection criteria include reinforced IEC 60747-17 rating, fail-safe default-low output mode, tri-state outputs with side-specific enables, and compatibility with isolated motor control, battery management, and traction inverter interfaces.
Technical Context
The SI86S663EE-IS2R implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and delivering superior CMTI (>100 kV/µs) and noise immunity versus optocouplers. Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with RSTB– threshold at ~1.7 V and tSTART of 0.3 ms.
It integrates six unidirectional channels (A1–A6 → B1–B6), each with 50 Ω nominal output impedance and configurable fail-safe state. The device uses HF XMTR/RCVR circuitry per channel and requires only 0.1 µF + 10 µF bypass capacitors per supply rail-no external magnetics or timing components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed serial links including isolated SPI and QSPI interfaces without protocol translation. |
| Isolation rating | 6000 VRMS for 1 minute - meets reinforced insulation requirements per UL 1577, VDE 60747-17, and CSA 62368-1 for safety-critical automotive and industrial systems. |
| Propagation delay | 10 ns typical - enables tight-timing control loops in motor gate drivers and real-time power converter feedback paths. |
| Supply voltage | 2.25–5.5 V per side - allows direct interface with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting. |

Pinout & Package
SI86S663EE-IS2R is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance optimized for 6000 VRMS reinforced insulation. Pin 1 is marked with a dot; pins 1–8 are Side A (input side), pins 9–16 are Side B (output side), separated by an internal semiconductor isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power domain | Supplies and grounds all input-side logic and transmitter circuits; requires local 0.1 µF + 10 µF decoupling. |
| A1–A6 | Side A digital inputs | Unidirectional input channels mapped 1:1 to B1–B6; accept Schmitt-trigger + CMOS thresholds for noise immunity. |
| EN1 | Side A output enable | Active-high control: drives all B-side outputs into high-impedance when low-enables shared-bus arbitration. |
| VDD2, GND2 | Side B power domain | Independent supply domain for output-side receivers and drivers; supports galvanic separation from controller side. |
| B1–B6 | Side B digital outputs | Isolated, buffered outputs with 50 Ω impedance; default-low fail-safe state confirmed for SI86S663 variant. |
| EN2 | Side B output enable | Active-high control: places all B outputs in tri-state-allows safe hot-plug or multi-master bus configurations. |
Key Features
| Feature | Design Value |
|---|---|
| No-startup initialization | RF modulation architecture eliminates boot-up delay or configuration sequence-outputs become valid within 0.3 ms of VDD stabilization. |
| Reinforced safety certification | UL 1577 (6000 VRMS), VDE 60747-17, CSA 62368-1, and CQC GB4943.1 - enables single-component compliance for end-equipment safety approvals. |
| Fail-safe default-low output | Ordering option 'E' in SI86S663EE-IS2R guarantees B-side outputs drive low during VDD1 undervoltage or loss-critical for fault-containment in gate drivers. |
| Tri-state outputs with dual enables | EN1 and EN2 independently disable all outputs on respective sides-supports bidirectional bus sharing and dynamic power gating. |
| High CMTI immunity | ≥100 kV/µs common-mode transient immunity - maintains signal integrity in SiC/GaN inverter switching nodes with >50 V/ns dV/dt. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6603ARIZ-RL | 6-channel, 5000 VRMS, 100 Mbps, integrated isolated DC-DC; no AEC-Q100 qualification. | Suitable for industrial PLCs where on-chip power is preferred but automotive qualification is not required. | Select ADUM6603ARIZ-RL when isolated power delivery is needed alongside signal isolation and AEC-Q100 is unnecessary. |
| ISO6763RQWR | 6-channel, 5000 VRMS, 50 Mbps, 25 ns propagation delay, automotive-grade (AEC-Q100 Grade 1), no fail-safe default-low option. | Fits cost-sensitive automotive modules where lower data rate suffices and fail-safe state is managed externally. | Choose ISO6763RQWR for entry-level automotive applications requiring basic isolation but not 150 Mbps or programmable fail-safe behavior. |
Compared with ADUM6603ARIZ-RL and ISO6763RQWR, SI86S663EE-IS2R delivers higher data rate (150 vs. 100/50 Mbps), superior isolation (6000 vs. 5000 VRMS), and factory-configured default-low fail-safe-making it optimal for next-generation EV power electronics demanding speed, safety, and deterministic fault response.

FAQ
What is the isolation voltage rating of the SI86S663EE-IS2R and which safety standards does it meet?
The SI86S663EE-IS2R provides 6000 VRMS reinforced isolation for 1 minute and is certified to UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1. These approvals validate its suitability for safety-critical automotive applications including ISO 26262-compliant systems where reinforced insulation is mandated for high-voltage barriers.
Does the SI86S663EE-IS2R require external configuration or initialization at power-up?
No, the SI86S663EE-IS2R requires no startup initialization due to its RF-based on/off keying architecture. Outputs become valid within 0.3 ms after VDD1/VDD2 rise above UVLO+ (2.18 V typical), and the device enters normal operation without firmware or register writes-reducing system boot complexity and latency.
What is the meaning of the 'EE' suffix in SI86S663EE-IS2R?
The 'EE' in SI86S663EE-IS2R indicates the device is configured with default-low fail-safe output behavior: when VDD1 is unpowered or below UVLO, B-side outputs drive low while VDD2 remains powered. This ordering option ensures safe shutdown states in gate driver and protection circuits.
Can the SI86S663EE-IS2R be used in both automotive and industrial applications?
Yes, the SI86S663EE-IS2R is AEC-Q100 Grade 1 qualified (–40 to +125 °C) and supports industrial temperature range operation. Its 6000 VRMS isolation, 100 kV/µs CMTI, and reinforced safety certifications make it suitable for both automotive traction inverters and industrial motor drives requiring high reliability and safety compliance.
What are the supply bypass requirements for stable operation of the SI86S663EE-IS2R?
The SI86S663EE-IS2R requires 0.1 µF ceramic + 10 µF bulk capacitors placed between VDD1–GND1 and VDD2–GND2, located as close as possible to the respective pins. This dual-capacitor network suppresses high-frequency noise and sustains transient current demands during 150 Mbps switching-ensuring stable UVLO and output driver performance.
