Product details
Overview
SI86S620FE-AS4R 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 systems. It features Schmitt-trigger 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 and noise immunity are critical.
For engineers reviewing the SI86S620FE-AS4R datasheet, SI86S620FE-AS4R pinout, SI86S620FE-AS4R application, or SI86S620FE-AS4R equivalent, key selection criteria include its 10 ns typical propagation delay, 100 kV/µs CMTI, dual-channel SSO-8 package, and automotive-grade safety certifications including VDE 60747-17 and UL 1577.
Technical Context
The SI86S620FE-AS4R implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture delivers precise timing with ≤4.5 ns pulse width distortion and supports independent UVLO and reset on both sides (VDD1/VDD2).
It integrates input deglitch filtering (36 ns) and offers fail-safe operation via ordering option: SI86S620FE-AS4R is configured for default-low output during power loss on Side A while Side B remains powered. Supply bypass requires 0.1 µF + 10 µF per side, and output impedance is 50 Ω ±40%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps - enables high-speed CAN FD, SPI, or isolated ADC interface without protocol bottlenecks |
| Propagation delay | 5–14 ns (typ. 10 ns) - ensures tight timing alignment in motor gate driver feedback loops |
| Isolation rating | 6000 VRMS (1 min) - meets reinforced insulation requirements for 1000 VDC bus systems |
| CMTI | 100 kV/µs - sustains reliable operation during fast-switching transients in SiC/GaN inverters |
| Supply range | 2.25–5.5 V - supports direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends |
| Operating temp | –40 to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 1 |
| Fail-safe mode | Default low output - prevents unintended activation of downstream power stages during VDD1 loss |
Pinout & Package
SI86S620FE-AS4R uses an SSO-8 (wide-body SOIC-8) package with 8.0 mm creepage/clearance, optimized for 6000 VRMS reinforced insulation. Pin 1 = VDD1, Pin 2 = A1, Pin 3 = A2, Pin 4 = GND1, Pin 5 = GND2, Pin 6 = B1, Pin 7 = B2, Pin 8 = VDD2. Pins A1/A2 and B1/B2 are unidirectional digital I/O channels across the isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Side A power supply | Supplies isolated input-side logic; must be decoupled with 0.1 µF + 10 µF capacitors |
| A1, A2 | Side A digital inputs | Accept CMOS/Schmitt-trigger signals; support 36 ns deglitch filtering |
| GND1 | Side A ground reference | Forms isolated return path for Side A; must be physically separated from GND2 |
| GND2 | Side B ground reference | Forms isolated return path for Side B; defines safety barrier between domains |
| B1, B2 | Side B digital outputs | Drive 50 Ω loads directly; default low during VDD1 undervoltage (fail-safe) |
| VDD2 | Side B power supply | Supplies isolated output-side logic; independent of VDD1 for asymmetric rail designs |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and temperature drift; achieves stable 150 Mbps performance over full temperature range |
| Selectably fail-safe output | Factory-configured default-low state prevents unsafe actuation in BMS fault conditions when VDD1 collapses |
| 36 ns input deglitch filter | Rejects EMI-induced glitches below 36 ns width-critical for noisy motor control environments |
| 100 kV/µs CMTI | Ensures signal integrity during 1000 V/µs common-mode transients in 800 V EV inverters |
| AEC-Q100 Grade 1 | Validated for automotive use up to +125 °C ambient; includes PPAP documentation and IMDS support |

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 |
|---|---|---|---|
| ADUM220N0BRZ-RL7 | 5000 VRMS isolation, 150 Mbps, default-high fail-safe, SOIC-8 (narrow body) | Lacks AEC-Q100 qualification; lower creepage (3.9 mm) limits use in >400 V systems | Prefer for industrial non-automotive designs where cost and footprint are prioritized over automotive compliance |
| ISO7721DWR | 5000 VRMS, 100 Mbps, 11 ns propagation delay, SOIC-8 (narrow body), no deglitch filter | No input deglitching; not AEC-Q100 qualified; lower CMTI (85 kV/µs) | Choose when lower data rate suffices and system-level filtering is already implemented |
Compared with ADUM220N0BRZ-RL7 and ISO7721DWR, SI86S620FE-AS4R provides higher isolation (6000 VRMS), automotive qualification, integrated 36 ns deglitching, and superior CMTI-making it the only option suitable for ASIL-B–compliant BMS and traction inverter subsystems.

FAQ
What is the isolation voltage rating of the SI86S620FE-AS4R?
The SI86S620FE-AS4R is rated for 6000 VRMS isolation per UL 1577 (1 minute), with reinforced insulation certified to VDE 60747-17 and CSA 62368-1. Its SSO-8 package provides 8.0 mm creepage and clearance, enabling use in 1000 VDC systems meeting IEC 61000-4-5 surge requirements. This rating is validated across the full –40 to +125 °C operating range.
Does the SI86S620FE-AS4R require external startup initialization?
No, the SI86S620FE-AS4R requires no startup initialization due to its RF-based modulation architecture. It begins transmitting valid data within 300 µs of VDD1/VDD2 reaching UVLO+ thresholds (2.18 V typ.), with outputs held low by internal 100 kΩ pulldowns until stabilization. This eliminates firmware boot dependencies and simplifies system power sequencing.
What fail-safe behavior does the SI86S620FE-AS4R exhibit during power loss?
The SI86S620FE-AS4R is factory-configured for default-low fail-safe operation: when VDD1 drops below UVLO– (2.05 V typ.), outputs B1 and B2 transition to logic low within 12 ns (tSD max) while VDD2 remains powered. This prevents unintended activation of downstream MOSFETs or relays in battery management and motor control applications.
How does the SI86S620FE-AS4R handle high-noise environments like motor drives?
The SI86S620FE-AS4R combats noise via three mechanisms: 36 ns input deglitch filtering rejects sub-duration EMI pulses; 100 kV/µs CMTI withstands fast dv/dt transients; and Schmitt-trigger inputs provide 15% VDD hysteresis. These features ensure reliable operation in SiC/GaN inverter gate driver feedback paths without external RC filtering.
Is the SI86S620FE-AS4R compatible with 3.3 V and 5 V logic interfaces?
Yes, the SI86S620FE-AS4R supports 2.25–5.5 V supplies on both sides independently. At 3.3 V, it delivers 150 Mbps with 9 ns typical propagation delay and 4.5 ns pulse width distortion; at 5.0 V, power consumption increases marginally but timing improves slightly. Input thresholds scale with VDD (VIH = 0.7×VDD, VIL = 0.3×VDD), ensuring interoperability.
