Product details
Overview
SI8630ED-ASR from Skyworks is a triple-channel, unidirectional digital isolator with reinforced 5 kVRMS isolation, Schmitt-trigger inputs, and selectable high-fail-safe output mode. It operates from 2.5–5.5 V on both sides, achieves ≤13 ns propagation delay, supports up to 150 Mbps data rate, and is rated for –40 to +125 °C operation in industrial and automotive systems including battery management and traction inverters.
For engineers reviewing the SI8630ED-ASR datasheet, SI8630ED-ASR pinout, SI8630ED-ASR application, or SI8630ED-ASR equivalent, this page delivers verified electrical specs, fail-safe behavior under power loss, CMTI ≥50 kV/µs, SOIC-16 wide-body package details, and two validated alternative part numbers for isolated signal integrity design.
Technical Context
The SI8630ED-ASR implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its three isolated channels are all input-side (VDD1) to output-side (VDD2) unidirectional, with no enable pins (EN1/EN2 not present per Si8630 family definition).
Fail-safe default-high output is implemented via internal 2 µA pull-ups on all output pins when VDD1 is unpowered but VDD2 remains active. Propagation delay skew between channels is ≤2.5 ns, and pulse width distortion is ≤4.5 ns-enabling precise timing in motor control gate drivers and isolated ADC interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS reinforced insulation (UL, VDE, CSA, CQC certified); enables use in mains-connected industrial drives and EV battery systems. |
| Max Data Rate | 150 Mbps-supports high-speed SPI, RS-485 transceiver control, and real-time PWM feedback in inverters. |
| Propagation Delay | 5–13 ns (typ. 8 ns)-ensures sub-10 ns timing alignment critical for synchronous isolated gate drivers. |
| Supply Voltage Range | 2.5–5.5 V on both VDD1 and VDD2-interoperates with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| CMTI | ≥50 kV/µs (Si8630xB/C/D grade)-rejects fast common-mode transients in high-dV/dt motor phases and DC-link switching nodes. |
| Operating Temperature | –40 to +125 °C-qualified for under-hood automotive applications including on-board chargers and traction inverters. |
| Fail-Safe Mode | Default-high output (ordering option 'ED')-guarantees safe logic-high state during input-side power loss in safety-critical monitoring paths. |
Pinout & Package
SI8630ED-ASR is housed in a RoHS-compliant 16-pin wide-body SOIC package (7.5 mm creepage/clearance), supporting reinforced insulation up to 5 kVRMS. Pin 1 is marked with a dot; the package meets JEDEC MS-013AC and is compatible with standard reflow profiles (peak 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side supply | Power for channel input circuitry (pins A1–A3); must be bypassed with 0.1 µF capacitor to GND1. |
| GND1 | Input-side ground | Reference for input signals and VDD1; requires low-inductance connection to minimize noise coupling. |
| A1–A3 | Input channels | Three digital inputs referenced to VDD1/GND1; Schmitt-triggered for >0.44 V hysteresis and noise rejection. |
| VDD2 | Output-side supply | Power for output drivers (pins B1–B3); independent of VDD1-enables level shifting and dual-supply operation. |
| GND2 | Output-side ground | Reference for outputs and VDD2; galvanically isolated from GND1; must be separated by ≥8 mm creepage in PCB layout. |
| B1–B3 | Output channels | Three isolated CMOS outputs referenced to VDD2/GND2; default-high during VDD1 loss due to internal 2 µA pull-ups. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates LED aging and temperature drift-ensures stable timing and 60-year lifetime at rated working voltage. |
| Sub-10 ns propagation delay | Enables tight-loop control in servo drives and digital power supplies where <10 ns channel-to-channel skew is required. |
| 50 kV/µs CMTI | Prevents output glitches during 1500 V common-mode transients-critical for IGBT/SiC gate driver isolation in inverters. |
| Fail-safe high output (ED variant) | Guarantees known logic state during input-side brownout-used in fault-monitoring paths for ISO 26262 ASIL-B systems. |
| 2.5–5.5 V dual-supply operation | Supports mixed-voltage systems: e.g., 3.3 V MCU on VDD1 side and 5 V analog sensor interface on VDD2 side. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM130D0BRZ | Triple-channel, 3.75 kVRMS, 150 Mbps, default-low output, 16-pin SOIC narrow body. | Lacks 5 kVRMS reinforced rating and automotive qualification; suitable only for non-safety-critical industrial use. | Select when 3.75 kV isolation suffices and cost sensitivity outweighs automotive qualification needs. |
| ISO6731FDWR | Triple-channel, 5 kVRMS, 50 Mbps, default-high output, 16-pin SOIC wide body, lower power at 1 Mbps. | Lower data rate limits use in high-speed SPI or fast PWM; lacks AEC-Q100 qualification despite same package. | Select when bandwidth demand is ≤50 Mbps and ultra-low static current (<1 mA/channel at 1 Mbps) is prioritized. |
Compared with ADUM130D0BRZ and ISO6731FDWR, SI8630ED-ASR uniquely combines 5 kVRMS reinforced isolation, AEC-Q100 Grade 0 qualification, 150 Mbps speed, and default-high fail-safe behavior-making it the only drop-in solution for ASIL-B traction inverter monitoring and high-voltage BMS designs requiring guaranteed high-state signaling during input-side power loss.

FAQ
What is the isolation rating and safety certification status of SI8630ED-ASR?
SI8630ED-ASR provides 5 kVRMS reinforced isolation and is certified to UL 1577, CSA Component Acceptance Notice 5A, VDE EN 60747-5-5, IEC 60950-1, and CQC GB4943.1 standards. It meets reinforced insulation requirements per IEC 60601-1 for medical equipment and supports 10 kV surge capability in T-variant versions-though SI8630ED-ASR itself is rated for 5 kVRMS per minute.
Does SI8630ED-ASR support bidirectional communication?
No, SI8630ED-ASR is a unidirectional isolator with three input channels (A1–A3) on the VDD1 side and three corresponding output channels (B1–B3) on the VDD2 side. It does not include enable pins or reverse-direction paths-unlike Si8631 variants. Bidirectional operation requires separate forward/reverse isolators or a different family member such as Si864x.
What is the meaning of the 'ED' suffix in SI8630ED-ASR?
The 'ED' suffix in SI8630ED-ASR denotes a specific configuration: triple-channel (3 inputs, 0 outputs on VDD1 side), 5 kVRMS isolation rating, and default-high fail-safe output mode. This means that when VDD1 is unpowered but VDD2 remains active, all B1–B3 outputs assert logic high via internal 2 µA pull-ups-critical for safety-critical monitoring circuits.
How does SI8630ED-ASR handle undervoltage conditions on either supply rail?
SI8630ED-ASR features independent undervoltage lockout (UVLO) on both VDD1 and VDD2 rails, with thresholds of ~2.24 V (rising) and ~2.16 V (falling). If VDD1 drops below UVLO, inputs are ignored and outputs hold their last valid state until VDD1 recovers or the fail-safe condition activates. If VDD2 drops, outputs go undefined until VDD2 stabilizes-per Table 3.1 in the datasheet.
Is SI8630ED-ASR qualified for automotive applications?
Yes, SI8630ED-ASR carries the '-A' suffix indicating full AEC-Q100 Grade 0 qualification (–40 to +125 °C), AIAG-compliant PPAP documentation, IMDS/CAMDS material declarations, and automotive-specific manufacturing flow. It is approved for use in on-board chargers, battery management systems, and traction inverters in hybrid and battery electric vehicles.
