Product details
Overview
SI8462AA-B-IS1 from Skyworks Solutions is a six-channel, ultra-low-power digital isolator in a 16-pin narrow-body SOIC package, supporting up to 150 Mbps data rate with worst-case propagation delay <9.5 ns, 0.5 ns channel-to-channel skew, and 25 kV/µs common-mode transient immunity. It operates across 2.70–5.5 V supply rails and delivers <13.3 mA per side at 100 Mbps (5 V), enabling high-speed isolation in motor control and isolated power supplies.
For engineers reviewing the SI8462AA-B-IS1 datasheet, SI8462AA-B-IS1 pinout, SI8462AA-B-IS1 application, or SI8462AA-B-IS1 equivalent, this page provides verified electrical specs, safety certifications (UL, CSA, VDE), thermal performance (–40 to 125 °C), and real-world design context for industrial automation and hybrid electric vehicle systems.
Technical Context
The SI8462AA-B-IS1 implements capacitive isolation with on-chip RF modulation/demodulation circuitry, delivering precise timing and robust noise rejection without external components beyond VDD bypass capacitors. Its architecture supports independent primary- and secondary-side supply domains (VDD1/VDD2), enabling level-shifting between 2.70 V and 5.5 V logic domains.
All six channels are unidirectional, with three channels routed from side A to side B and three from side B to side A - confirmed by pin mapping and functional description in Rev. 1.6 datasheet Section 2.3 and Table 7. The device achieves reinforced insulation rated to 2500 VRMS and meets IEC 60747-5-2, UL 1577, and CSA Component Notice 5A requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Six unidirectional channels: 3 A→B + 3 B→A, enabling full-duplex isolated communication paths. |
| Max Data Rate | 150 Mbps - supports high-speed serial interfaces such as isolated SPI, RS-485 transceivers, and gate driver feedback loops. |
| Propagation Delay | 3.0–9.5 ns (typ/max) - ensures sub-10 ns timing accuracy critical for PWM synchronization in motor inverters. |
| Channel-Channel Skew | 0.5 ns (typ) - maintains tight timing alignment across multiple isolated signals in ADC sampling or encoder interfaces. |
| CMTI | 25 kV/µs - rejects fast transients in noisy industrial environments, preventing false triggering in isolated gate drivers. |
| Supply Voltage Range | 2.70–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| Isolation Rating | 2500 VRMS (1 min) - certified for reinforced insulation per UL, CSA, and VDE standards in safety-critical systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM1402ARWZ | Four-channel, 100 Mbps max, 25 kV/µs CMTI, SOIC-16 wide-body (10.3 mm × 10.3 mm); higher propagation delay (22 ns typ). | Limited to four channels; unsuitable for full six-signal isolation in 3-phase motor control without stacking. | Select when only four isolated signals are needed and board space permits wider SOIC footprint. |
| ISO6763 | Six-channel, 50 Mbps max, 25 kV/µs CMTI, SOIC-16 narrow-body; lower power but insufficient for 150 Mbps SPI or encoder interfaces. | Cannot support high-speed serial protocols above 50 Mbps; requires redesign for >100 Mbps use cases. | Choose for cost-sensitive, lower-data-rate applications where 150 Mbps capability is unnecessary. |
Compared with ADUM1402ARWZ and ISO6763, SI8462AA-B-IS1 uniquely delivers six-channel, 150 Mbps isolation in the same narrow-body SOIC footprint while maintaining <9.5 ns propagation delay and 0.5 ns channel skew - making it optimal for space-constrained, high-performance motor control and BMS designs.

FAQ
What is the maximum operating temperature for SI8462AA-B-IS1 at 150 Mbps?
The SI8462AA-B-IS1 supports continuous operation at –40 to 125 °C ambient temperature when running at 150 Mbps with 15 pF load and 5 V supply, as specified in Table 1 of the Rev. 1.6 datasheet. This rating applies to the narrow-body SOIC package and is validated across all six channels simultaneously.
Does SI8462AA-B-IS1 require external passive components for basic operation?
No. SI8462AA-B-IS1 requires only VDD bypass capacitors (0.1 µF ceramic per supply rail) for stable operation - no external resistors, transformers, or timing components are needed. This simplifies layout and reduces BOM count compared to optocoupler-based isolation.
How many of the six channels in SI8462AA-B-IS1 are bidirectional?
None of the six channels in SI8462AA-B-IS1 are bidirectional. It contains three dedicated A→B unidirectional channels (driven by INA1–INA3, output on OUTA1–OUTA3) and three dedicated B→A unidirectional channels (driven by INB1–INB3, output on OUTB1–OUTB3), as defined in Section 2.3 and Table 7 of the datasheet.
What safety certifications apply to SI8462AA-B-IS1?
SI8462AA-B-IS1 is certified to UL 1577 (2500 VRMS), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (reinforced insulation). All certifications apply to the 2.5 kVRMS-rated narrow-body SOIC variant and are production-tested to 3.0 kVRMS for 1 second.
Can SI8462AA-B-IS1 operate with different supply voltages on each side?
Yes. SI8462AA-B-IS1 supports independent VDD1 (2.70–5.5 V) and VDD2 (2.70–5.5 V) supplies, enabling level translation between 3.3 V and 5 V domains without external level shifters. This is confirmed in Tables 1–5 and Section 2.3 of the Rev. 1.6 datasheet.
