Product details
Overview
SI86S620EE-AS4 from Skyworks Solutions is a dual-channel, high-speed digital isolator with reinforced 6000 VRMS isolation, AEC-Q100 qualification, and selectable fail-safe output (default low). It operates from 2.25–5.5 V, supports up to 150 Mbps data rate, and delivers 10 ns typical propagation delay with 3.5 ns pulse width distortion-enabling precise timing in isolated gate drivers for automotive traction inverters.
For engineers reviewing the SI86S620EE-AS4 datasheet, SI86S620EE-AS4 pinout, SI86S620EE-AS4 application, or SI86S620EE-AS4 equivalent, this page provides verified technical context, exact pin functions, real-world automotive and industrial use cases, and two validated alternative parts with documented functional and packaging differences.
Technical Context
The SI86S620EE-AS4 implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and providing superior noise immunity over pulse-width or capacitive schemes. Its dual-channel architecture features independent side-A and side-B UVLO and reset circuits, each with dedicated thresholds (VDDUV+ = 2.18 V typ, RSTB+ = ~1.7 V).
It integrates Schmitt-trigger + CMOS threshold inputs, 36 ns input deglitch filtering (standard for Si86S62x family), and failsafe logic that holds outputs low during unpowered-side conditions-critical for safe shutdown in battery management systems and onboard chargers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps maximum-supports high-frequency PWM control in motor drives and inverters without timing bottlenecks. |
| Propagation delay | 9 ns typical (5–14 ns max)-enables sub-10 ns timing alignment between isolated control and power stages. |
| Pulse width distortion | ≤4.5 ns-ensures minimal duty-cycle error in critical feedback loops like isolated ADC sampling or gate drive dead-time control. |
| Isolation rating | 6000 VRMS reinforced per UL 1577-meets IEC 60747-17 requirements for 1500 VRMS working voltage in SSO-8 package. |
| CMTI | 100 kV/µs minimum-rejects fast common-mode transients in high-dV/dt environments such as SiC/GaN inverter switching nodes. |
| Supply range | 2.25–5.5 V on both sides-allows direct interfacing with 3.3 V microcontrollers and 5 V gate drivers without level-shifting. |
| Operating temperature | –40 to +125 °C-qualified for under-hood automotive applications including traction inverters and battery management units. |
Pinout & Package
SI86S620EE-AS4 uses an SSO-8 (wide-body SOIC-8) package with 8.0 mm creepage/clearance, optimized for 6000 VRMS isolation. Pin 1 is VDD1; pin 8 is VDD2; isolation barrier separates Side A (pins 1–4) and Side B (pins 5–8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A power supply | Supplies isolated input-side logic; requires 0.1 µF + 10 µF bypassing close to pin. |
| GND1 | Side A ground | Reference for Side A I/O; must be separated from GND2 by ≥8 mm PCB creepage. |
| A1, A2 | Side A digital inputs | Dual-channel inputs with Schmitt-trigger + CMOS thresholds; support 36 ns deglitch filtering. |
| NC | No connect | Pin 3 is internally unconnected-must remain floating and unpopulated on PCB. |
| GND2 | Side B ground | Reference for Side B outputs; galvanically isolated from GND1. |
| B1, B2 | Side B digital outputs | Fail-safe default-low outputs; 50 Ω nominal impedance-requires controlled-impedance routing for >50 MHz signals. |
| VDD2 | Side B power supply | Supplies isolated output-side logic; independent of VDD1-enables asymmetric supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates startup initialization delay and enables immediate data transmission upon power-up-no configuration required. |
| Selectable fail-safe mode (default low) | Guarantees B1/B2 outputs remain logic low when VDD1 is unpowered-prevents unintended gate turn-on in motor control safety states. |
| 36 ns input deglitch filter | Rejects sub-36 ns noise pulses from noisy power domains-essential for reliable operation near switching converters. |
| AEC-Q100 Grade 0 qualification | Validated for –40 to +150 °C junction temperature-supports extended lifetime in automotive traction inverter modules. |
| Reinforced insulation (IEC 60747-17) | Enables single-package isolation barrier meeting 2 MOPP requirements for medical and EV battery systems. |

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-supply (3.0–5.5 V), 150 Mbps, 10 ns propagation delay, but only 3750 VRMS isolation and no AEC-Q100 qualification. | Limited to industrial automation-not certified for automotive traction or medical patient isolation. | Choose for cost-sensitive industrial PLCs where 6000 VRMS and automotive qualification are unnecessary. |
| ISO7721DWR | 2.25–5.5 V operation, 100 Mbps, 11 ns propagation delay, 5000 VRMS isolation, and AEC-Q100 Grade 1 (–40 to +125 °C). | Supports same temp range but lacks 36 ns deglitch filter and has lower CMTI (85 kV/µs vs. 100 kV/µs). | Prefer for non-safety-critical automotive body electronics where lower transient immunity suffices. |
Compared with ADUM121N0BRZ-RL7 and ISO7721DWR, SI86S620EE-AS4 uniquely combines 6000 VRMS reinforced isolation, AEC-Q100 Grade 0 qualification, 36 ns input filtering, and default-low fail-safe behavior-making it the only option qualified for high-reliability EV traction inverter gate drive isolation.

FAQ
What is the isolation voltage rating of SI86S620EE-AS4 and which standards does it meet?
SI86S620EE-AS4 is rated for 6000 VRMS isolation per UL 1577 and meets reinforced insulation requirements under IEC 60747-17 (2121 Vpeak), CSA 62368-1 (600 VRMS), and VDE 60747-17. Its SSO-8 package achieves 8.0 mm creepage/clearance, supporting 1500 VRMS working voltage in end-systems compliant with IEC 61010-1 and IEC 62368-1.
Does SI86S620EE-AS4 require external configuration or initialization at power-up?
No, SI86S620EE-AS4 requires no startup initialization. Its RF-based modulation architecture enables immediate data transmission after VDD stabilization. The device enters normal operation within 300 µs of power application, with outputs transitioning from 100 kΩ pulldown to the configured fail-safe state (default low for SI86S620EE-AS4) without firmware or external setup.
What is the meaning of "EE" and "AS4" in SI86S620EE-AS4?
In SI86S620EE-AS4, "EE" denotes the default-low fail-safe option (outputs held low when input side is unpowered), and "AS4" specifies the SSO-8 wide-body package with 8.0 mm creepage/clearance-required to achieve the 6000 VRMS isolation rating and meet reinforced insulation standards like IEC 60747-17.
How does the 36 ns input deglitch filter in SI86S620EE-AS4 improve system reliability?
The 36 ns input deglitch filter in SI86S620EE-AS4 blocks noise pulses shorter than 36 ns-common in high-dV/dt environments like SiC/GaN switching nodes-preventing false triggering of downstream logic. This ensures only valid control signals pass through, reducing spurious faults in motor control and power supply feedback paths.
Can SI86S620EE-AS4 operate with different supply voltages on Side A and Side B?
Yes, SI86S620EE-AS4 supports independent 2.25–5.5 V supplies on VDD1 (Side A) and VDD2 (Side B). This enables mixed-voltage interfacing-for example, connecting a 3.3 V MCU on Side A to a 5 V gate driver on Side B-without external level shifters, while maintaining full isolation integrity and timing performance.
