Product details
Overview
SI8630BT-AS from Skyworks is an automotive-grade, triple-channel digital isolator with reinforced 5 kVRMS isolation, 150 Mbps data rate, <10 ns propagation delay, and selectable fail-safe low-default output state. It operates across –40 to +125 °C and supports 2.5–5.5 V supply on both sides, enabling use in high-reliability battery management systems and traction inverters.
For engineers reviewing the SI8630BT-AS datasheet, SI8630BT-AS pinout, SI8630BT-AS application, or SI8630BT-AS equivalent, this page delivers verified electrical specs, fail-safe behavior timing, SOIC-16 wide-body package details, and automotive-qualified alternatives for functional safety-critical designs.
Technical Context
The SI8630BT-AS implements RF-based on/off keying across a semiconductor isolation barrier-no startup initialization required. Its architecture delivers robust noise immunity with 100 kV/µs common-mode transient immunity (CMTI) and stable timing over temperature.
All three channels are unidirectional (3-input, 0-output on VDD1 side; 0-input, 3-output on VDD2 side), with Schmitt-trigger inputs, internal undervoltage lockout (UVLO), and fail-safe operation triggered by input-side power loss. The device is AEC-Q100 qualified and certified to VDE 0884-10 for reinforced insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces like SPI, RS-485, and isolated CAN FD transceivers without bottlenecking. |
| Propagation Delay | 5–13 ns - enables precise timing synchronization in motor control gate drivers and real-time feedback loops. |
| Isolation Rating | 5 kVRMS reinforced - meets IEC 60747-5-5 and VDE 0884-10, suitable for 800 V battery systems with creepage/clearance compliance. |
| Supply Voltage Range | 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 Default | Low output on VDD1 loss - ensures safe shutdown of downstream power stages during controller power failure. |
| CMTI | 60–100 kV/µs - prevents false triggering in high-dV/dt environments such as SiC/GaN inverter switching nodes. |
| Operating Temperature | –40 to +125 °C - validated for under-hood and battery-pack mounting locations in BEV/OBC applications. |
Pinout & Package
SI8630BT-AS uses a RoHS-compliant 16-pin wide-body SOIC package (WB SOIC-16) with 8.3 mm creepage and 8.2 mm clearance, supporting reinforced insulation up to 5 kVRMS. Pin 1 is marked with a dot; pin count and spacing comply with JEDEC MS-013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies logic and RF transmitter circuitry; requires 0.1 µF bypass capacitor to GND1. |
| GND1 | Input-side ground reference | Return path for VDD1; must be separated from GND2 by ≥8.2 mm for reinforced isolation. |
| INA | Channel A input | Schmitt-triggered, 1.4–1.9 V VIH threshold; accepts 2.5–5.5 V logic levels directly. |
| INB | Channel B input | Identical to INA; independent input with same noise-immune threshold hysteresis. |
| INC | Channel C input | Third isolated input channel; no enable control-always active when VDD1 powered. |
| VDD2 | Output-side power supply | Supplies RF receiver and output drivers; bypass capacitor required to GND2. |
| GND2 | Output-side ground reference | Galvanically isolated return for VDD2; defines secondary-side logic domain. |
| OUTA | Channel A output | 50 Ω nominal output impedance; drives 15 pF loads at 150 Mbps with <4 ns rise/fall time. |
| OUTB | Channel B output | Matched timing to OUTA: ≤2.5 ns channel-to-channel skew ensures synchronized signal delivery. |
| OUTC | Channel C output | Fail-safe low default: asserts logic low within 12 ns after VDD1 collapse while VDD2 remains active. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation barrier | Eliminates LED aging and temperature drift issues of optocouplers; enables 60-year lifetime at rated voltage. |
| Selectably fail-safe output | Factory-configured low-default state ensures predictable deactivation of gate drivers or fault latches during MCU brownout. |
| VDE 0884-10 reinforced rating | Validated for 10 kV surge capability and 5 kVRMS working voltage-certified for functional safety in ASIL-C systems. |
| AEC-Q100 Grade 0 qualification | Tested across –40 to +150 °C ambient with zero-defect manufacturing flow-supports automotive OBC and BMS deployment. |
| Ultra-low power at 100 Mbps | 5.5 mA per channel at 5 V / 100 Mbps-reduces thermal load in densely packed power modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3300ARWZ | 3-channel, 25 Mbps max rate, 2.5 kVRMS isolation, no VDE 0884-10 certification | Limited to industrial automation where 5 kVRMS and automotive qualification are not required | Lower cost for non-automotive, lower-speed designs; lacks fail-safe configuration and reinforced surge rating |
| ISO7731FDWR | 3-channel, 100 Mbps, 5 kVRMS, VDE-certified, but only industrial-grade (–40 to +125 °C, no AEC-Q100) | Suitable for industrial inverters and medical equipment, not automotive safety-critical systems | Drop-in replacement for non-automotive 5 kVRMS applications; lacks automotive PPAP documentation and IMDS support |
Compared with SI8630BT-AS, ADUM3300ARWZ offers lower performance and no automotive qualification, while ISO7731FDWR matches isolation and temperature range but omits AEC-Q100 validation and fail-safe factory configuration-making SI8630BT-AS the sole choice for ASIL-B/C BMS and traction inverter designs requiring production traceability.

FAQ
What is the isolation rating and safety certification of SI8630BT-AS?
SI8630BT-AS provides 5 kVRMS reinforced isolation and is certified to UL 1577, CSA Component Notice 5A, VDE 0884-10, IEC 60747-5-5, and CQC GB4943.1. These certifications validate its use in functional safety applications up to ASIL-C, including battery management and traction inverter systems where reinforced insulation is mandated.
Does SI8630BT-AS support fail-safe operation, and how is it configured?
Yes, SI8630BT-AS has factory-configured fail-safe behavior: outputs default to logic low when VDD1 is lost while VDD2 remains powered. This is fixed at manufacture-no external configuration is needed. The timing is guaranteed ≤12 ns from VDD1 collapse to valid low output, ensuring deterministic shutdown of downstream power stages.
What is the maximum data rate and propagation delay of SI8630BT-AS?
SI8630BT-AS supports up to 150 Mbps data rate with typical propagation delay of 8 ns and a maximum of 13 ns across –40 to +125 °C. This enables reliable high-speed communication in SPI-isolated ADC interfaces and isolated gate driver command links without timing bottlenecks.
Is SI8630BT-AS qualified for automotive applications, and what does that entail?
Yes, SI8630BT-AS is AEC-Q100 Grade 0 qualified and built using full automotive process flows-including AIAG-compliant PPAP documentation, IMDS/CAMDS material reporting, and zero-defect methodology. It is intended for under-hood and battery-pack applications where long-term reliability and traceability are mandatory.
What package type and pin compatibility does SI8630BT-AS use?
SI8630BT-AS uses a 16-pin wide-body SOIC (WB SOIC-16) package with 10.3 mm body width, 8.3 mm creepage, and 8.2 mm clearance. It shares footprint and pinout with other Si863x variants in the same package-enabling drop-in replacement within the family for different channel counts or fail-safe configurations.
