Product details
Overview
SI8630BT-IS2 from Skyworks is a triple-channel, unidirectional digital isolator with 3 input channels on VDD1 side and 0 on VDD2 side, rated for 5 kVRMS reinforced 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 (1.6 mA/channel at 1 Mbps, 5 V).
For engineers reviewing the SI8630BT-IS2 datasheet, SI8630BT-IS2 pinout, SI8630BT-IS2 application, or SI8630BT-IS2 equivalent, this device serves as a high-reliability isolation solution in automotive battery management systems, industrial motor drives, and isolated power supplies where reinforced insulation, AEC-Q100 qualification, and precise timing (<10 ns propagation delay) are critical.
Technical Context
The SI8630BT-IS2 implements RF-based on/off keying across a semiconductor isolation barrier-replacing optocoupler architectures with superior noise immunity, no start-up initialization, and stable performance across temperature and lifetime. Its architecture delivers deterministic timing with <2.5 ns channel-to-channel skew and 350 ps peak jitter.
All three channels are input-only on the VDD1 side (A1–A3), driving outputs B1–B3 on the isolated VDD2 side. The device includes undervoltage lockout (UVLO) on both sides, Schmitt-trigger inputs for >400 mV hysteresis, and failsafe behavior defined at power loss: outputs default to logic low when VDD1 is unpowered and VDD2 remains active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS reinforced insulation per UL/VDE/IEC standards - enables use in safety-critical automotive and industrial mains-connected systems. |
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces including SPI, RS-485 transceiver control, and real-time feedback loops in inverters. |
| Propagation Delay | 5–13 ns (typ. 8 ns) - ensures sub-10 ns timing predictability for closed-loop motor control and isolated ADC sampling synchronization. |
| Channel-Channel Skew | 0.4–2.5 ns (typ. 0.5 ns) - guarantees tight inter-channel alignment for multi-signal isolation (e.g., PWM pairs or encoder quadrature signals). |
| Supply Voltage Range | 2.5–5.5 V on both sides - allows interoperability with 3.3 V microcontrollers and 5 V legacy peripherals without level-shifting. |
| CMTI | 60–100 kV/µs (Si8630BT-IS2 is T-grade) - suppresses false triggering in high-dV/dt environments like IGBT gate drivers and SiC power stages. |
| Fail-Safe Default | Logic low output during VDD1 loss - provides safe shutdown state for enable/disable control of downstream power stages. |
Pinout & Package
SI8630BT-IS2 is housed in a RoHS-compliant wide-body SOIC-16 package (7.5 mm creepage/clearance), certified to VDE 0884-10 for reinforced insulation and 10 kV surge capability. This package meets reinforced insulation requirements for 5 kVRMS working voltage in end-equipment standards (IEC 61010-1, 60601-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side supply | Power for input-side logic and RF transmitter; must be bypassed with 0.1 µF capacitor near pin. |
| GND1 | Input-side ground | Reference for A1–A3 inputs and VDD1; requires low-inductance connection to isolate noise coupling. |
| A1–A3 | Digital inputs | CMOS/Schmitt-trigger inputs accepting 2.5–5.5 V logic; no external pull-ups required for default-low configuration. |
| VDD2 | Output-side supply | Power for RF receiver and output drivers; independent of VDD1 for true galvanic isolation. |
| GND2 | Output-side ground | Reference for B1–B3 outputs; physically separated from GND1 by isolation barrier. |
| B1–B3 | Digital outputs | Push-pull CMOS outputs with ~50 Ω impedance; drive 15 pF loads directly at 150 Mbps with <4 ns rise/fall times. |
| NC | No-connect | Pins 1, 2, 15, 16 are internally unused; may be left floating, tied to VDD2, or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced VDE 0884-10 certification | Enables single-package isolation for functional safety applications up to SIL-3/PL e without external components. |
| AEC-Q100 Grade 1 qualification | Validated for automotive operation from –40 to +125 °C with zero-defect manufacturing flow and PPAP support. |
| Ultra-low dynamic power | 5.5 mA/channel at 100 Mbps (5 V) - reduces thermal load in dense PCB layouts and extends battery life in portable BMS. |
| Fail-safe low-default output | Guarantees B1–B3 go low within 12 ns of VDD1 collapse - critical for safe disable of gate drivers or contactors. |
| 60 kV/µs CMTI (T-grade) | Prevents metastability in noisy 400–800 V DC bus environments typical in EV traction inverters and OBCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8630BD-B-IS | Same 3-channel, 5 kVRMS, wide-body SOIC-16, but D-grade (not T-grade); CMTI = 50 kV/µs (vs. 60–100 kV/µs); no VDE 0884-10 certification. | Approved for industrial (not automotive) use; lacks AEC-Q100 qualification and reinforced surge rating. | Select when cost sensitivity outweighs automotive qualification and highest CMTI; verify end-equipment surge test margins. |
| ISO6731FDWR | Texas Instruments' 3-channel isolator; 5 kVRMS, SOIC-16 WB; CMTI = 85 kV/µs; propagation delay 11 ns (max); no fail-safe low option. | Requires external pull-down for low-default behavior; not AEC-Q100 qualified; different pinout (EN pins present). | Choose if TI ecosystem integration or higher CMTI is prioritized over guaranteed fail-safe state and automotive traceability. |
Compared with SI8630BD-B-IS and ISO6731FDWR, the SI8630BT-IS2 uniquely combines AEC-Q100 Grade 1, VDE 0884-10 reinforcement, 60–100 kV/µs CMTI, and factory-configured fail-safe low output - making it the only drop-in solution for automotive BMS and OBC designs requiring full safety certification and deterministic power-loss behavior.

FAQ
What is the isolation rating and certification status of SI8630BT-IS2?
The SI8630BT-IS2 is rated for 5 kVRMS reinforced isolation and certified to UL 1577, CSA Component Acceptance Notice 5A, VDE 0884-10 (reinforced), IEC 60950-1, IEC 61010-1, and CQC GB4943.1. Its VDE 0884-10 certification confirms suitability for functional safety applications up to SIL-3 in end equipment. SI8630BT-IS2 is also AEC-Q100 Grade 1 qualified for automotive use from –40 to +125 °C.
Does SI8630BT-IS2 support fail-safe operation, and how is it configured?
Yes, SI8630BT-IS2 has factory-configured fail-safe behavior: outputs B1–B3 default to logic low when VDD1 is unpowered and VDD2 remains active. This is an ordering-option feature (denoted by "T" in the part number), not user-programmable. The transition occurs within 12 ns of VDD1 collapse, ensuring rapid, deterministic shutdown of downstream circuitry. No external components are needed to implement this behavior.
What are the supply voltage and power consumption characteristics of SI8630BT-IS2?
SI8630BT-IS2 operates from 2.5 V to 5.5 V on both VDD1 and VDD2 sides. At 5 V and 1 Mbps, it draws 1.6 mA per channel (4.8 mA total). At 100 Mbps, consumption rises to 5.5 mA per channel (16.5 mA total). At 2.5 V and 1 Mbps, it consumes 1.5 mA per channel. These values reflect its ultra-low-power RF isolation architecture, enabling efficient operation in thermally constrained automotive and industrial modules.
How does SI8630BT-IS2 achieve high noise immunity, and what is its CMTI rating?
SI8630BT-IS2 achieves high noise immunity through RF-based on/off keying (not pulse-width modulation), Schmitt-trigger inputs with 440 mV typical hysteresis, and differential RF detection. Its CMTI is rated at 60–100 kV/µs - the upper range applies to T-grade devices like SI8630BT-IS2 - validated per VDE 0884-10 test conditions. This exceeds typical requirements for SiC/GaN inverter gate drive isolation and ensures reliable operation in high-dV/dt battery systems.
What is the pin configuration and package type of SI8630BT-IS2?
SI8630BT-IS2 uses a wide-body SOIC-16 package (7.5 mm creepage/clearance) with 3 input pins (A1–A3) on the VDD1 side, 3 output pins (B1–B3) on the VDD2 side, and dedicated VDD1/GND1 and VDD2/GND2 supplies. Pins 1, 2, 15, and 16 are NC. The package supports reflow soldering per JEDEC J-STD-020 (260 °C peak) and is RoHS-compliant. SI8630BT-IS2 has no enable pins - all channels are always active.
