Product details
Overview
SI8610ED-AS from Skyworks Solutions is a single-channel, ultra-low-power digital isolator with 5 kVRMS reinforced isolation, 150 Mbps data rate, <10 ns propagation delay, and Schmitt-trigger inputs for high noise immunity-used in isolated ADC interfaces and motor control gate drivers where signal integrity across galvanic barriers is critical.
For engineers reviewing the SI8610ED-AS datasheet, SI8610ED-AS pinout, SI8610ED-AS application, or SI8610ED-AS equivalent, this page delivers verified specifications, WB SOIC-16 package layout, fail-safe output configuration, CMTI of 100 kV/µs, and automotive-grade AEC-Q100 qualification-enabling rapid selection for high-reliability industrial and EV power systems.
Technical Context
The SI8610ED-AS implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and delivering stable timing performance across –40°C to +125°C. Its dual-supply architecture (VDD1/VDD2 = 2.5–5.5 V) supports independent side operation with undervoltage lockout on both sides.
It features selectable fail-safe mode (default high output), precise timing (0.5 ns channel-channel skew, 2 ns propagation delay skew), and 50 Ω nominal output impedance optimized for controlled-impedance PCB traces-critical for high-speed serial links in isolated power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, RS-485, and CAN FD isolation without external clock conditioning. |
| Isolation rating | 5 kVRMS reinforced - certified to UL 1577, VDE 0884-10, and IEC 62368-1 for safety-critical industrial and automotive applications. |
| Propagation delay | 5.0–14 ns - enables sub-10 ns timing-critical feedback loops in digital power controllers and motor gate drivers. |
| CMTI | 100 kV/µs - maintains signal integrity during fast-switching transients in SiC/GaN inverters and isolated DC-DC converters. |
| Supply voltage | 2.5–5.5 V per side - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting. |
| Fail-safe mode | Default high output - ensures predictable logic state during input-side power loss in safety-monitored systems. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive and industrial ambient environments without derating. |
Pinout & Package
SI8610ED-AS is packaged in a wide-body SOIC-16 (WB SOIC-16) with 8.3 mm creepage/clearance, supporting reinforced insulation up to 5 kVRMS. Pin 1 is GND1; pins 2, 5, 6, 8, 10, 11, 12, and 15 are NC (no connect); pin 4 is A1 (Side 1 I/O); pin 13 is B1 (Side 2 I/O).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND1 (Pin 1) | Side 1 ground reference | Provides low-impedance return path for VDD1 and A1 signals; must be decoupled with 0.1 µF capacitor near pin. |
| VDD1 (Pin 3) | Side 1 supply input | Accepts 2.5–5.5 V; powers transmitter side; requires local 0.1 µF bypass capacitor. |
| A1 (Pin 4) | Side 1 digital I/O | Unidirectional input or output; Schmitt-triggered for >0.44 V hysteresis; compatible with CMOS/TTL logic levels. |
| GND1 (Pin 7) | Side 1 ground reference | Second ground connection for Side 1; improves noise rejection and thermal dissipation in high-current layouts. |
| GND2 (Pin 9) | Side 2 ground reference | Isolated return for VDD2 and B1; separates primary and secondary domains to maintain galvanic isolation integrity. |
| B1 (Pin 13) | Side 2 digital I/O | Unidirectional output; default-high fail-safe behavior ensures logic HIGH when VDD1 is unpowered and VDD2 is active. |
| VDD2 (Pin 14) | Side 2 supply input | Accepts 2.5–5.5 V; powers receiver side; independent of VDD1 for asymmetric supply configurations. |
| GND2 (Pin 16) | Side 2 ground reference | Second ground connection for Side 2; required for full reinforced insulation compliance and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates optical degradation and startup delays-enables immediate data transmission after power-on without handshake or calibration. |
| Selectably fail-safe output | Factory-configured default-high output ensures safe system state during input-side brownout or controller reset events. |
| Ultra-low power at 100 Mbps | 5.5 mA per channel at 5 V / 100 Mbps-reduces thermal load in densely packed power modules and extends battery life in portable test equipment. |
| 60-year lifetime at rated voltage | Guarantees long-term reliability in infrastructure applications such as solar inverters and industrial PLCs without field replacement planning. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125°C ambient-supports onboard chargers, battery management systems, and traction inverter control boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM1100ARZ | Single-channel, 100 Mbps, 2.5 kVRMS basic isolation, SOIC-8 package, no fail-safe option. | Limited to non-safety-critical industrial controls; lacks reinforced certification and default-high output behavior. | Choose ADUM1100ARZ only if 2.5 kVRMS isolation suffices and fail-safe state is managed externally via pull-up resistors. |
| ISO6710DWR | Single-channel, 50 Mbps, 5 kVRMS reinforced, SOIC-16, default-low fail-safe, 100 kV/µs CMTI. | Lower data rate restricts use in high-speed serial interfaces; default-low output may require redesign of safety logic. | Select ISO6710DWR when cost sensitivity outweighs speed needs and system architecture accommodates low-default fail-safe behavior. |
Compared with ADUM1100ARZ and ISO6710DWR, SI8610ED-AS uniquely combines 150 Mbps speed, 5 kVRMS reinforced isolation, factory-set default-high fail-safe, and AEC-Q100 qualification-making it optimal for next-generation EV powertrain and high-density industrial power supplies where timing, safety, and longevity are co-constrained.

FAQ
What is the isolation rating and safety certification status of the SI8610ED-AS?
The SI8610ED-AS provides 5 kVRMS reinforced isolation and is certified to UL 1577 (5000 VRMS, 1 min), VDE 0884-10 (reinforced), IEC 62368-1, and CSA standards. These certifications validate its suitability for safety-critical applications including EV battery management and industrial PLCs where reinforced insulation is mandated.
Does the SI8610ED-AS require external components for stable operation?
Yes-the SI8610ED-AS 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, as the device integrates internal fail-safe termination matching its default-high output configuration.
How does the fail-safe mode function in the SI8610ED-AS?
The SI8610ED-AS is factory-configured with default-high fail-safe mode: when VDD1 is unpowered but VDD2 remains active, the B1 output holds HIGH. This behavior is hardwired and does not require external configuration. It ensures predictable logic states during input-side power loss in safety-monitored systems.
What is the maximum data rate supported by the SI8610ED-AS, and how is signal integrity maintained?
The SI8610ED-AS supports up to 150 Mbps with peak eye diagram jitter of 350 ps and pulse width distortion ≤4.5 ns. Signal integrity is preserved via 100 kV/µs common-mode transient immunity, 0.5 ns channel-channel skew, and RF-based modulation-enabling clean high-speed serial communication across noisy power domains.
Is the SI8610ED-AS qualified for automotive applications?
Yes-the SI8610ED-AS is AEC-Q100 Grade 1 qualified (–40°C to +125°C), manufactured using automotive-specific process flows, and supported with AIAG-compliant PPAP documentation. It is approved for use in onboard chargers, battery management systems, and traction inverters in hybrid and battery electric vehicles.
