Product details
Overview
SI8630BT-IS 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 @ 1 Mbps, 5 V).
For engineers reviewing the SI8630BT-IS datasheet, SI8630BT-IS pinout, SI8630BT-IS application, or SI8630BT-IS equivalent, this device serves as a high-reliability isolation solution in automotive battery management systems, isolated switch-mode power supplies, and industrial motor control where reinforced insulation, low propagation delay skew (<2.5 ns), and AEC-Q100 qualification are critical selection criteria.
Technical Context
The SI8630BT-IS uses RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture delivers precise timing with ≤8 ns typical propagation delay, ≤0.5 ns channel-channel skew, and ≤2 ns propagation delay skew across temperature and voltage.
All three channels are input-only on the VDD1 side, with outputs exclusively on the VDD2 side. The device implements independent undervoltage lockout (UVLO) on both sides (VDDUV+ = 2.24 V typ), supports 2.5–5.5 V dual-supply operation, and integrates 10 µA pull-downs on all I/O for fail-safe low default state during input-side power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels & Direction | 3 unidirectional input channels (VDD1 side only); no reverse channels - enables clean signal splitting from controller to isolated peripherals. |
| Isolation Rating | 5 kVRMS reinforced insulation (VDE 0884-10 certified) - meets IEC 61010-1 and 60601-1 requirements for medical and industrial safety-critical systems. |
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces including isolated SPI clock lines and fast PWM feedback in traction inverters. |
| Propagation Delay | 5–13 ns (typ 8 ns) - ensures tight timing alignment in real-time motor control loops with minimal latency impact. |
| Channel-Channel Skew | 0.4–2.5 ns (typ 0.5 ns) - guarantees synchronized sampling across multiple isolated ADC/DAC channels in precision measurement systems. |
| CMTI | 60–100 kV/µs (Si8630BT-IS T-grade) - suppresses false triggering in high-dV/dt environments like SiC/GaN power stages. |
| Supply Range | 2.5–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting. |
Pinout & Package
SI8630BT-IS is housed in a RoHS-compliant wide-body SOIC-16 package (10.3 mm × 10.3 mm, creepage ≥8.3 mm), optimized for reinforced insulation and high-voltage spacing in automotive and industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side power supply | Supplies 2.5–5.5 V to input logic and RF transmitter; requires 0.1 µF bypass capacitor adjacent to pin. |
| GND1 | Input-side ground reference | Return path for VDD1; must be separated from GND2 by ≥8.3 mm creepage for reinforced isolation compliance. |
| INA, INB, INC | Digital input terminals | 3 Schmitt-triggered CMOS inputs accepting 2.0–5.5 V logic; internal 10 µA pull-downs enforce low default on power loss. |
| VDD2 | Output-side power supply | Supplies 2.5–5.5 V to RF receiver and output drivers; independent of VDD1 for true galvanic separation. |
| GND2 | Output-side ground reference | Return path for VDD2; electrically isolated from GND1; forms safety barrier between primary and secondary circuits. |
| OUTA, OUTB, OUTC | Digital output terminals | 3 CMOS outputs with 50 Ω nominal impedance; drive 15 pF loads at 150 Mbps with <4 ns rise/fall times. |
| NC (Pins 1, 9, 16) | No-connect terminals | Unbonded pins; must remain floating or tied to GND/VDD2 - no internal connection; improves creepage margin. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced VDE 0884-10 certification | Validated 5 kVRMS working voltage and 10 kV surge capability - eliminates need for external transient protection in EV charging stations. |
| AEC-Q100 Grade 1 qualification | Rated for –40 to +125 °C operation with zero-defect manufacturing flow - suitable for under-hood BMS and OBC modules. |
| Fail-safe low-default output | Guaranteed logic-low output when VDD1 is unpowered (tSD ≤12 ns) - prevents unintended gate drive activation in motor control fault conditions. |
| Ultra-low dynamic power | 5.5 mA/channel @ 100 Mbps, 5 V - reduces thermal load in densely packed power electronics enclosures. |
| High CMTI (100 kV/µs) | Immunity to fast common-mode transients from SiC inverters - maintains signal integrity without added filtering or layout complexity. |
Applications
| Battery Management System (BMS) | Isolated Switch-Mode Power Supply |

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, WB SOIC-16 package but rated to IEC 60747-5-5 (not VDE 0884-10); lacks 10 kV surge capability. | Suitable for industrial SMPS or PLCs where VDE reinforcement isn't mandated; lower cost where full automotive/safety certification isn't required. | Select SI8630BD-B-IS if VDE 0884-10 and 10 kV surge are not needed - reduces BOM cost without sacrificing isolation rating or performance. |
| ADUM3300ARWZ | 3-channel, 2.5 kVRMS, narrow-body SOIC-16; max 25 Mbps; no AEC-Q100 or VDE 0884-10 certification; higher 12 ns propagation delay. | Applicable in non-safety-critical industrial automation where lower speed and reduced isolation margin are acceptable. | Choose ADUM3300ARWZ only for cost-sensitive, non-automotive designs with <25 Mbps bandwidth needs and no reinforced insulation requirement. |
Compared with SI8630BD-B-IS and ADUM3300ARWZ, SI8630BT-IS uniquely combines VDE 0884-10 reinforcement, 150 Mbps speed, AEC-Q100 qualification, and fail-safe low default - making it the only option qualified for automotive BMS and high-reliability industrial inverters requiring full safety certification.

FAQ
What is the isolation rating and safety certification of SI8630BT-IS?
SI8630BT-IS provides 5 kVRMS reinforced isolation and is certified to VDE 0884-10, UL 1577, CSA 5A, and CQC GB4943.1 standards. It meets IEC 61010-1 and 60601-1 requirements for medical and industrial equipment, and its VDE 0884-10 rating includes 10 kV surge capability - a key differentiator over standard IEC 60747-5-5 isolators. This makes SI8630BT-IS suitable for high-reliability automotive and safety-critical systems.
Does SI8630BT-IS support fail-safe operation, and how is it configured?
Yes, SI8630BT-IS has a factory-configured fail-safe mode that drives all outputs low when the input-side supply (VDD1) is unpowered. This behavior is implemented via internal 10 µA pull-down resistors on all I/O pins and is guaranteed with tSD ≤12 ns. No external components or configuration pins are required - the fail-safe state is fixed at time of manufacture and cannot be changed in-circuit.
What are the supply voltage requirements for SI8630BT-IS?
SI8630BT-IS operates with independent 2.5–5.5 V supplies on both VDD1 (input side) and VDD2 (output side). Each supply requires a 0.1 µF ceramic bypass capacitor placed adjacent to its respective VDD pin. The device functions correctly across the full range without level shifters, supporting mixed-voltage systems such as 3.3 V MCUs driving 5 V gate drivers or isolated ADCs.
Is SI8630BT-IS qualified for automotive applications?
Yes, SI8630BT-IS is AEC-Q100 Grade 1 qualified (–40 to +125 °C) and manufactured using Skyworks' automotive-specific process flows, including AIAG-compliant PPAP documentation and IMDS/CAMDS material reporting. Its reinforced VDE 0884-10 rating and fail-safe low-default output make it appropriate for on-board chargers, battery management systems, and traction inverters in BEV/HEV platforms.
How does SI8630BT-IS achieve high noise immunity?
SI8630BT-IS achieves high noise immunity through three integrated mechanisms: Schmitt-trigger inputs with 0.44 V typical hysteresis, RF-based on/off keying modulation (superior to pulse coding), and 60–100 kV/µs common-mode transient immunity (CMTI). These features collectively suppress EMI-induced glitches in high-dV/dt environments like SiC/GaN power stages and industrial motor drives - eliminating the need for external RC filters or layout guard rings.
