Product details
Overview
SI8430BB-D-IS1 from Skyworks Solutions is a triple-channel, ultra-low-power digital isolator in a 16-pin wide-body SOIC package, supporting up to 150 Mbps data rate with worst-case propagation delay <9.5 ns, <1.5 ns pulse width distortion, and 0.5 ns channel-channel skew. It operates from 2.70–5.5 V on both sides, delivers 25 kV/µs common-mode transient immunity, and is certified for 2500 VRMS isolation per UL, CSA, and VDE standards-used in isolated ADC interfaces and motor control gate drivers.
For engineers reviewing the SI8430BB-D-IS1 datasheet, SI8430BB-D-IS1 pinout, SI8430BB-D-IS1 application, or SI8430BB-D-IS1 equivalent, this page provides verified timing specs, safety-certified isolation parameters, supply current vs. data rate curves at 2.7 V/3.3 V/5 V, and precise pin-level functional roles for layout-critical high-speed digital isolation design.
Technical Context
The SI8430BB-D-IS1 implements capacitive isolation with on-chip RF modulation/demodulation across three independent bidirectional channels. Its dual-supply architecture (VDD1/VDD2) enables level-shifting between 2.7–5.5 V domains without external logic, and integrated enable control allows output tri-state during power sequencing.
It features deterministic timing with guaranteed channel-to-channel skew ≤1.8 ns and propagation delay skew ≤3.0 ns over –40 to +125 °C, meeting AEC-Q100 Grade 0 requirements. The device requires only 0.1 µF bypass capacitors per supply rail and achieves <6 mA per channel at 100 Mbps under 5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 150 Mbps - supports high-speed SPI, RS-485 transceiver control, and real-time encoder feedback loops. |
| Propagation Delay | 3.0–9.5 ns - ensures sub-10 ns timing budget compliance for closed-loop motor control and isolated PWM generation. |
| Channel-Channel Skew | ≤1.8 ns - maintains phase alignment across three isolated signals in multi-phase inverter gate drive applications. |
| Common-Mode Transient Immunity | 25 kV/µs - prevents data corruption in noisy industrial environments with fast-switching IGBTs or SiC MOSFETs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM1300ARWZ | 3-channel, 100 Mbps max, 30 ns max propagation delay, SOIC-16 narrow body, 2.5 kVRMS isolation | Limited to 100 Mbps and higher timing uncertainty - unsuitable for 150 Mbps SPI or encoder interfaces requiring <10 ns delay. | Choose ADUM1300ARWZ only when lower data rate and narrower package footprint are prioritized over timing precision. |
| ISO6731FDWR | 3-channel, 50 Mbps max, 25 ns max propagation delay, SOIC-16 wide body, 5 kVRMS isolation | Higher isolation rating but halved data rate and doubled propagation delay - trades speed for enhanced safety margin in low-bandwidth sensing. | Choose ISO6731FDWR where reinforced 5 kVRMS isolation is mandatory and system bandwidth remains below 50 Mbps. |
Compared with ADUM1300ARWZ and ISO6731FDWR, SI8430BB-D-IS1 uniquely delivers 150 Mbps operation with sub-10 ns propagation delay and 0.5 ns channel skew in a wide-body SOIC, making it optimal for time-critical motor control and high-resolution isolated data acquisition where timing fidelity outweighs absolute isolation voltage.

The SI8430BB-D-IS1 supports a maximum data rate of 150 Mbps, verified across its full operating temperature range (–40 to +125 °C) and supply voltage range (2.70–5.5 V). This specification applies to the 'Bx' variant explicitly identified in Skyworks' Si8430/31/35 datasheet Rev. 1.7, Table 3 and Table 4 timing characteristics.
Does SI8430BB-D-IS1 require external startup configuration?
No, SI8430BB-D-IS1 requires no start-up initialization. Valid data appears at outputs within 40 µs of power application (tSU = 15–40 µs), as specified in Table 3 and Table 4 of the datasheet. This enables immediate functionality after power-on in safety-critical systems like motor drives and battery management units.
What safety certifications apply to SI8430BB-D-IS1?
SI8430BB-D-IS1 is certified to UL 1577 (2500 VRMS, 1 min), CSA Component Notice 5A (IEC 60950-1 and IEC 61010-1), and VDE IEC 60747-5-2 (reinforced insulation). These certifications are confirmed in Tables 6 and 7 of the Skyworks Si8430/31/35 datasheet Rev. 1.7 and apply to the 2.5 kVRMS-rated wide-body SOIC variant.
