Product details
Overview
SI86S620HE-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 of control and power domains is critical.
For engineers reviewing the SI86S620HE-AS4R datasheet, SI86S620HE-AS4R pinout, SI86S620HE-AS4R application, or SI86S620HE-AS4R equivalent, this page delivers verified technical context, precise timing specs (9 ns typical propagation delay), safety certification status (UL 1577, VDE 60747-17), and validated automotive-grade alternatives aligned to IEC 60747-17 reinforced insulation requirements.
Technical Context
The SI86S620HE-AS4R implements RF-based on/off keying across a semiconductor isolation barrier-no start-up initialization required. Its dual-channel architecture supports independent side-A (VDD1/GND1) and side-B (VDD2/GND2) power domains with UVLO thresholds at 2.18 V (rising) and 2.05 V (falling).
It integrates input deglitch filtering (36 ns), 100 kV/µs CMTI immunity, and failsafe logic that forces outputs low during VDD1 loss while VDD2 remains active. Timing performance includes 3.5 ns pulse width distortion and 0.7 ns channel-to-channel skew at 5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 150 Mbps - supports high-speed SPI, CAN FD, and isolated ADC interfaces without protocol bottlenecks |
| Propagation delay | 9 ns typical - enables tight timing closure in motor gate driver feedback loops |
| Isolation rating | 6000 VRMS - meets reinforced insulation requirements for 1000 VDC bus systems per UL 1577 |
| Supply voltage | 2.25–5.5 V - interoperable with 3.3 V microcontrollers and 5 V analog front-ends |
| Operating temperature | –40 to +125 °C - qualified for under-hood automotive environments per AEC-Q100 Grade 0 |
| CMTI | 100 kV/µs - suppresses false triggering in high-dV/dt inverter switching nodes |
| Fail-safe mode | Default low output - ensures safe shutdown state when side-A power fails in BMS monitoring circuits |
Pinout & Package
SI86S620HE-AS4R uses an NB SOIC-8 package (3.9 mm creepage/clearance) with 8-pin layout optimized for reinforced isolation. Pin 1 = VDD1, Pin 2 = A1, Pin 3 = A2, Pin 4 = GND1, Pin 5 = GND2, Pin 6 = B1, Pin 7 = B2, Pin 8 = VDD2. No-connect (NC) pin is not present-full 8-pin utilization confirms dual-channel bidirectional I/O capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, VDD2 | Independent power supplies | Enables level-shifting between 2.5 V MCU and 5 V gate driver domains without shared ground |
| A1, A2 | Side-A digital inputs/outputs | Accepts CMOS/Schmitt-trigger signals; drives 50 Ω output impedance for controlled-impedance PCB routing |
| B1, B2 | Side-B digital inputs/outputs | Provides isolated logic-level outputs compatible with IGBT/SiC gate drivers and ADC reference domains |
| GND1, GND2 | Isolated ground references | Physically separates noisy power-ground from clean signal-ground; prevents ground-loop noise injection |
Key Features
| Feature | Design Value |
|---|---|
| RF modulation architecture | Eliminates start-up delay and initialization sequences-output valid within 300 µs of power application |
| Input deglitch filter | 36 ns pulse rejection-suppresses EFT bursts and MOSFET switching noise before crossing isolation barrier |
| UVLO with reset detection | Separate 2.18 V/2.05 V thresholds per side plus RSTB±1.7 V reset-prevents metastability during brownout |
| Reinforced insulation | 6000 VRMS withstand, 1500 VRMS working voltage (SSO-8), and VDE 60747-17 compliance-certified for medical and EV traction systems |
| Automotive qualification | AEC-Q100 Grade 0, PPAP documentation support, IMDS/CAMDS listings-meets OEM Tier-1 supply chain traceability |
Applications

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, but only 105 °C max operating temperature and no AEC-Q100 qualification | Suitable for industrial automation but not automotive traction systems requiring 125 °C ambient | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| ISO7721DWR | 5000 VRMS, 100 Mbps max data rate, 10 ns propagation delay, and no input deglitch filter | Valid for general-purpose isolated UART/RS-485 but lacks noise immunity for high-dV/dt motor control | Choose for non-critical communications where 150 Mbps and 36 ns filtering are unnecessary |
Compared with ADUM220N0BRZ-RL7 and ISO7721DWR, the SI86S620HE-AS4R uniquely combines AEC-Q100 Grade 0, 6000 VRMS reinforced isolation, 150 Mbps speed, and integrated 36 ns input filtering-making it the only option qualified for safety-critical EV battery and inverter subsystems.

FAQ
What is the isolation voltage rating of the SI86S620HE-AS4R and which standards does it meet?
The SI86S620HE-AS4R has a 6000 VRMS isolation rating per UL 1577 and meets reinforced insulation requirements under VDE 60747-17, CSA 62368-1, and CQC GB4943.1. It achieves 1500 VRMS working voltage in SSO-8 configuration and is certified for medical (60601-1, 2 MOPP) and automotive applications. This rating is validated through 1-minute dielectric withstand testing.
Does the SI86S620HE-AS4R require external startup initialization or configuration?
No, the SI86S620HE-AS4R requires no startup initialization or configuration. Its RF-based modulation architecture delivers valid output within 300 µs of power application. The device enters normal operation automatically after VDD exceeds the 2.18 V UVLO+ threshold, with no firmware, register writes, or external clock needed-reducing system boot complexity.
What fail-safe behavior does the SI86S620HE-AS4R exhibit during loss of side-A supply?
The SI86S620HE-AS4R is ordered with default-low fail-safe mode (denoted by "HE" suffix). When VDD1 drops below UVLO– (2.05 V) while VDD2 remains powered, outputs B1 and B2 are actively driven low. This behavior prevents undefined states in gate driver or BMS monitoring circuits during MCU power faults.
How does the SI86S620HE-AS4R handle high common-mode transients in inverter applications?
The SI86S620HE-AS4R provides 100 kV/µs common-mode transient immunity (CMTI), measured at ±1500 V common-mode step. This performance suppresses false triggering caused by fast dV/dt edges in SiC/IGBT half-bridges. Its RF modulation scheme inherently rejects magnetic coupling better than pulse-based isolators.
Is the SI86S620HE-AS4R pin-compatible with other devices in the Si86S6xx family?
Yes, the SI86S620HE-AS4R shares identical NB SOIC-8 pinout and footprint with all Si86S61x/S62x variants (e.g., SI86S621HE-AS4R, SI86S622HE-AS4R). Channel count, fail-safe polarity, and data rate variant (B/E vs F/H) are differentiated by part number-not pin assignment-enabling flexible design reuse and BOM optimization.
