Product details
Overview
SI8630BC-AS1 from Skyworks is a triple-channel, unidirectional digital isolator with 3 input channels on VDD1 side and 0 on VDD2 side, rated for 3.75 kVRMS isolation, 150 Mbps data rate, and –40 to +125 °C operation. It features Schmitt-trigger inputs, selectable fail-safe low-default output, and ultra-low power consumption (1.5 mA/channel @ 1 Mbps, 2.5 V).
For engineers reviewing the SI8630BC-AS1 datasheet, SI8630BC-AS1 pinout, SI8630BC-AS1 application, or SI8630BC-AS1 equivalent, this page delivers verified electrical specs, automotive-grade AEC-Q100 qualification, narrow-body SOIC-16 package details, and real-world timing performance including 8 ns typical propagation delay and 0.4 ns channel-channel skew.
Technical Context
The SI8630BC-AS1 implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity. Its architecture supports independent undervoltage lockout (UVLO) on both sides (VDD1/VDD2), with thresholds of 2.24 V (rising) and 2.16 V (falling), and 70 mV hysteresis.
All three channels are input-only on the VDD1 side, driving outputs B1–B3 on the isolated VDD2 side. The device operates with no enable pins (EN1/EN2 not present), and default-low fail-safe behavior is hardwired per ordering option-ensuring B1–B3 assert logic low during VDD1 loss while VDD2 remains powered.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8630BC-B-IS1 | Industrial-grade (–I suffix), identical electrical specs and pinout; lacks AEC-Q100 qualification and automotive PPAP documentation | Suitable for non-automotive industrial systems where extended temperature range and safety certification are required but automotive traceability is not | Select SI8630BC-B-IS1 for cost-sensitive industrial designs without automotive compliance mandates |
| ADUM130N0BRZ | Analog Devices' 3-channel isolator; 150 Mbps, 3.75 kV rating, but higher 10 ns propagation delay and 2.5 ns channel skew | Valid for general-purpose isolation but less suitable for time-critical motor control where sub-1 ns skew is required | Choose ADUM130N0BRZ only if legacy Analog Devices design ecosystem or specific package footprint compatibility is prioritized |
Compared with SI8630BC-AS1, SI8630BC-B-IS1 offers identical performance at lower cost for non-automotive use, while ADUM130N0BRZ trades timing precision for broader vendor support-making SI8630BC-AS1 optimal for AEC-Q100-compliant, skew-sensitive automotive and industrial power systems.

FAQ
What is the isolation rating and safety certification status of the SI8630BC-AS1?
The SI8630BC-AS1 is rated for 3.75 kVRMS isolation and certified to UL 1577, CSA Component Notice 5A, IEC 60950-1 (reinforced), and CQC GB4943.1. It meets reinforced insulation requirements for industrial and automotive end-equipment, with full AEC-Q100 Grade 1 qualification confirming suitability for automotive applications from –40 to +125 °C.
Does the SI8630BC-AS1 require external components for basic operation?
Yes-the SI8630BC-AS1 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/down resistors are needed due to its Schmitt-trigger inputs and fail-safe default-low outputs, which eliminate external biasing components.
How does the fail-safe mode function in the SI8630BC-AS1?
The SI8630BC-AS1 has a hardwired fail-safe mode that forces outputs B1–B3 to logic low when VDD1 is unpowered (e.g., during input-side brownout), while VDD2 remains active. This behavior is fixed by the "C" in the part number and ensures safe shutdown of downstream power stages without software intervention or external circuitry.
What is the maximum data rate and timing performance of the SI8630BC-AS1?
The SI8630BC-AS1 supports up to 150 Mbps data rate with 8 ns typical propagation delay, 0.4 ns typical channel-channel skew, and 5 ns minimum pulse width. These values are guaranteed over –40 to +125 °C and enable precise synchronization in high-speed motor control, isolated ADC interfaces, and digital power management systems.
Is the SI8630BC-AS1 pin-compatible with other members of the Si863x family?
Yes-the SI8630BC-AS1 uses the same narrow-body SOIC-16 footprint and pinout as all Si8630x variants (e.g., SI8630BB-AS1, SI8630EC-AS1). Electrical differences (isolation rating, default output state) are implemented internally; no PCB layout change is required when substituting within the same package variant.
