Product details
Overview
SI8610BD-AS from Skyworks Solutions is a single-channel, ultra-low-power digital isolator with reinforced 5 kVRMS 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 SI8610BD-AS datasheet, SI8610BD-AS pinout, SI8610BD-AS application, or SI8610BD-AS equivalent, this page delivers verified specifications, WB SOIC-16 package layout, fail-safe output configuration, CMTI of 50 kV/µs, and automotive-grade AEC-Q100 qualification-enabling rapid selection for industrial and EV power systems.
Technical Context
The SI8610BD-AS implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling robust operation without external clocks or timing constraints. Its dual-supply architecture (VDD1/VDD2) supports independent 2.5–5.5 V domains on each side.
It features selectable fail-safe mode (default low output), undervoltage lockout per side (UVLO+ = 2.24 V typ), and precise timing with 0.5 ns channel-channel skew and 5 ns minimum pulse width-critical for synchronous sampling and PWM edge alignment in isolated feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed serial links like SPI, RS-485, and isolated CAN FD transceivers. |
| 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-100 ns loop timing in isolated current sensing and digital power control. |
| Supply voltage | 2.5–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| CMTI | 50 kV/µs - ensures reliable operation in high-dV/dt environments such as motor drives and inverters. |
| Fail-safe mode | Default low output - maintains safe state during input-side power loss, preventing unintended gate activation in IGBT/MOSFET drivers. |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive use and industrial ambient conditions. |
Pinout & Package
SI8610BD-AS is supplied in a wide-body SOIC-16 (WB SOIC-16) package with 8.3 mm creepage/clearance, supporting reinforced insulation up to 5 kVRMS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND1 (Pin 1, 7) | Side 1 ground reference | Provides return path for VDD1 domain; must be decoupled with 0.1 µF capacitor near Pin 3. |
| VDD1 (Pin 3) | Side 1 supply input | Accepts 2.5–5.5 V; powers input-side logic and RF transmitter circuitry. |
| A1 (Pin 4) | Digital input/output (Side 1) | Unidirectional data input to isolator; Schmitt-triggered for >0.44 V hysteresis against EMI. |
| GND2 (Pin 9, 16) | Side 2 ground reference | Isolated return for VDD2 domain; separates high-noise power stage ground from controller ground. |
| B1 (Pin 13) | Digital output (Side 2) | Isolated output driving gate driver or ADC clock; 50 Ω nominal impedance for controlled-impedance trace routing. |
| VDD2 (Pin 14) | Side 2 supply input | Independent 2.5–5.5 V supply for output-side receiver and driver; enables level-shifting functionality. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization required | Outputs become valid within 40 µs of VDD application-eliminates boot-time delays in real-time control systems. |
| Selectable fail-safe output | Ordering option BD denotes default-low behavior; prevents false turn-on of power switches during brownout. |
| Ultra-low power at 100 Mbps | 1.2 mA (VDD1) + 4.4 mA (VDD2) at 2.5 V - reduces thermal load in densely packed inverters and battery management units. |
| Precise timing performance | 0.5 ns channel-channel skew and 2 ns propagation delay skew - enables accurate multi-channel synchronization in isolated ADC/DAC systems. |
| AEC-Q100 Grade 1 qualification | Validated for automotive applications including onboard chargers and traction inverters operating from –40 °C to +125 °C. |

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 use; lacks reinforced certification and default-low configuration. | Choose ADUM1100ARZ only when 2.5 kVRMS and SOIC-8 footprint suffice and fail-safe behavior is not required. |
| ISO6710DR | Single-channel, 50 Mbps, 5 kVRMS reinforced, SOIC-8, default-high fail-safe only. | Lower data rate restricts use in high-speed feedback loops; default-high may conflict with gate driver safety logic. | Select ISO6710DR if cost sensitivity outweighs speed needs and system design accommodates default-high assertion on power loss. |
Compared with ADUM1100ARZ and ISO6710DR, SI8610BD-AS uniquely combines 150 Mbps speed, 5 kVRMS reinforced isolation, default-low fail-safe, and WB SOIC-16 creepage-making it optimal for next-generation EV power stages requiring both performance and functional safety compliance.

FAQ
What is the isolation rating and safety certification of the SI8610BD-AS?
The SI8610BD-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 automotive onboard chargers and industrial inverters where galvanic separation must withstand sustained high voltage and transient surges.
Does the SI8610BD-AS require external components for stable operation?
Yes-the SI8610BD-AS requires a 0.1 µF 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 due to internal fail-safe circuitry, but series termination (50–300 Ω) is recommended on noisy PCB traces to suppress reflections.
How does the fail-safe mode function in the SI8610BD-AS?
The SI8610BD-AS has a factory-configured default-low fail-safe mode: when VDD1 is unpowered but VDD2 remains active, the B1 output holds low. This prevents unintended activation of downstream power devices during input-side brownout or fault conditions-critical for IGBT/MOSFET gate driver safety in motor control and EV applications.
What is the maximum data rate supported by the SI8610BD-AS, and how does it perform at high speeds?
The SI8610BD-AS supports up to 150 Mbps with guaranteed timing parameters. At 100 Mbps, it draws only 1.2 mA on VDD1 and 4.4 mA on VDD2 at 2.5 V, and maintains 5 ns minimum pulse width and 350 ps peak eye diagram jitter-enabling clean signal transmission in high-speed SPI, digital encoder, and isolated communication links.
Is the SI8610BD-AS qualified for automotive applications?
Yes-the SI8610BD-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 deployed in production automotive systems including battery management systems, onboard chargers, and traction inverters.
