Product details
Overview
SI8620ET-IS2 from Skyworks Solutions is a dual-channel, reinforced-isolation digital isolator in a wide-body SOIC-16 package, supporting up to 150 Mbps data rate, <10 ns propagation delay, and 5 kVRMS isolation. It features Schmitt-trigger inputs, selectable fail-safe output (default high), and operates from 2.5–5.5 V across –40 to 125 °C for use in battery management systems and traction inverters.
For engineers reviewing the SI8620ET-IS2 datasheet, SI8620ET-IS2 pinout, SI8620ET-IS2 application, or SI8620ET-IS2 equivalent, key selection criteria include its 5 kVRMS reinforced VDE 0884-10 certification, dual-channel bidirectional capability, 60-year lifetime at rated voltage, and automotive-grade AEC-Q100 qualification for high-reliability isolated signal transmission.
Technical Context
The SI8620ET-IS2 implements RF-based on/off keying across a semiconductor isolation barrier, eliminating start-up initialization and enabling robust noise immunity without optical components. Its architecture delivers precise timing with ≤0.5 ns channel-channel skew and ≤2 ns propagation delay skew.
It supports independent undervoltage lockout (UVLO) on both sides (VDD1/VDD2), with thresholds of 1.95–2.375 V rising and 1.88–2.325 V falling, and integrates 50 Ω nominal output impedance per channel for controlled-impedance PCB routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - enables high-speed serial communication in motor control and power inverters. |
| Isolation rating | 5 kVRMS reinforced - certified to VDE 0884-10 and UL 1577, suitable for safety-critical automotive and industrial mains-connected systems. |
| Propagation delay | 5–14 ns - ensures deterministic timing in real-time feedback loops such as PWM gate driving. |
| Supply voltage | 2.5–5.5 V - supports interoperability with 3.3 V and 5 V logic domains without level-shifting. |
| Operating temperature | –40 to 125 °C - meets automotive under-hood and industrial ambient requirements. |
| Common-mode transient immunity | 60 kV/µs - maintains signal integrity in high-dV/dt environments like IGBT/SiC switching nodes. |
| Fail-safe mode | Default high output - ensures known state during VDD1 loss while VDD2 remains powered, critical for safe shutdown sequencing. |
Pinout & Package
SI8620ET-IS2 is housed in a WB SOIC-16 package with 8.3 mm creepage/clearance, supporting reinforced insulation. Pin assignments are validated per Skyworks datasheet revision 206328B.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND1 (Pins 1, 7) | Side 1 ground reference | Provides return path for input-side logic; must be decoupled with 0.1 µF capacitor near Pin 3 (VDD1). |
| VDD1 (Pin 3) | Side 1 supply | Power source for input-side circuitry; accepts 2.5–5.5 V; UVLO active below ~2.2 V. |
| A1 (Pin 4), A2 (Pin 5) | Side 1 digital I/O | Bidirectional channels - support data transmission from side 1 to side 2; Schmitt-trigger inputs enhance noise margin. |
| GND2 (Pins 9, 16) | Side 2 ground reference | Isolated return for output-side logic; requires separate 0.1 µF bypass cap near Pin 14 (VDD2). |
| VDD2 (Pin 14) | Side 2 supply | Independent power domain for output-side circuitry; enables galvanic separation of control and power stages. |
| B1 (Pin 13), B2 (Pin 12) | Side 2 digital I/O | Corresponding output channels - deliver isolated signals to MCU or gate driver; default-high fail-safe ensures defined state during input-side brownout. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates LED aging and temperature drift issues of optocouplers; no start-up initialization required. |
| Reinforced VDE 0884-10 certification | Enables single-component isolation barrier compliance in medical (IEC 60601-1) and industrial (IEC 62368-1) safety standards. |
| 60-year lifetime at rated voltage | Guarantees long-term reliability in battery electric vehicle (BEV) applications where replacement is impractical. |
| Ultra-low power at 100 Mbps | 5.5 mA per channel at 5 V - reduces thermal load in densely packed power modules and onboard chargers. |
| Selectably fail-safe output | Factory-configured default-high behavior ensures safe deactivation of downstream drivers during input-side power loss. |

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 |
|---|---|---|---|
| ADUM2201ARWZ | 2.5 kVRMS basic isolation; 100 Mbps max; SOIC-8 package; no AEC-Q100. | Suitable for non-safety-critical industrial automation, not automotive or reinforced-insulation systems. | Select when cost sensitivity outweighs safety certification and high-speed requirements. |
| ISO7721FDWR | 5 kVRMS reinforced; 100 Mbps; SOIC-8; 2.25–5.5 V; CMTI = 85 kV/µs. | Compatible in space-constrained designs but lacks AEC-Q100 and 150 Mbps capability. | Prefer for high-noise factory floor PLCs where footprint and CMTI are prioritized over automotive qualification. |
Compared with ADUM2201ARWZ and ISO7721FDWR, SI8620ET-IS2 uniquely combines AEC-Q100 qualification, 150 Mbps speed, and 5 kVRMS reinforced VDE 0884-10 certification in a wide-body SOIC-16-making it the only option qualified for automotive traction inverter signal isolation.

FAQ
What isolation rating does the SI8620ET-IS2 support, and which safety standards does it meet?
The SI8620ET-IS2 supports 5 kVRMS reinforced isolation and is certified to UL 1577 (5000 VRMS, 1 min), VDE 0884-10 (reinforced), IEC 62368-1, and IEC 60601-1. These certifications validate its use in safety-critical automotive and medical applications where double or reinforced insulation is mandated by end-equipment standards.
Does the SI8620ET-IS2 require external components for stable operation?
Yes, the SI8620ET-IS2 requires a 0.1 µF ceramic bypass capacitor between VDD1 and GND1, and another between VDD2 and GND2, placed as close as possible to the respective pins. No pull-up/pull-down resistors are needed-the SI8620ET-IS2 includes internal fail-safe biasing configured for default-high output per its ordering code.
How does the fail-safe mode function on the SI8620ET-IS2?
The SI8620ET-IS2 is factory-configured for default-high fail-safe mode: when VDD1 is unpowered but VDD2 remains active, outputs B1 and B2 remain logic high. This behavior is fixed per the part number and ensures predictable shutdown states in battery management and inverter control systems without external supervision.
What is the maximum data rate and associated timing performance of the SI8620ET-IS2?
The SI8620ET-IS2 supports up to 150 Mbps data rate with typical propagation delay of 8 ns, pulse width distortion of 1.5 ns, and channel-channel skew of 0.5 ns. These values are guaranteed across –40 to 125 °C and enable precise timing in high-frequency motor control and digital power conversion applications.
Is the SI8620ET-IS2 qualified for automotive applications, and what evidence supports this?
Yes, the SI8620ET-IS2 is AEC-Q100 qualified for Grade 1 (–40 to 125 °C) operation and supports AIAG-compliant PPAP documentation. Its automotive-grade qualification is confirmed in Skyworks' official datasheet (206328B), including IMDS/CAMDS listings and manufacturing flow controls specific to automotive reliability requirements.
