Product details
Overview
SI86S630EE-AS2 from Skyworks Solutions is a 3-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and dual 2.25–5.5 V supply operation. It features Schmitt-trigger + CMOS inputs, tri-state outputs with enable, and selectable fail-safe default-high/low output during power loss. Used in isolated ADC/DAC interfaces and motor control gate drivers where high CMTI and precise timing are critical.
For engineers reviewing the SI86S630EE-AS2 datasheet, SI86S630EE-AS2 pinout, SI86S630EE-AS2 application, or SI86S630EE-AS2 equivalent, key selection criteria include its 10 ns typical propagation delay, 3.5 ns pulse width distortion, AEC-Q100 qualification, –40 to 125 °C operating range, and WB SOIC-16 package with reinforced IEC 60747-17 insulation.
Technical Context
The SI86S630EE-AS2 implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and providing superior noise immunity over optical or capacitive alternatives. Its architecture supports independent UVLO and reset monitoring per side (VDD1/VDD2), with 100 kΩ weak pulldown during unpowered states and configurable fail-safe output polarity.
It integrates three bidirectional isolation channels with dedicated EN1/EN2 enable inputs, operates without external clock or configuration, and maintains signal integrity under transient stress up to 100 kV/µs. The device uses HF XMTR/RCVR circuitry for each channel and supports sleep mode via external control only in SM-series variants-not applicable to SI86S630EE-AS2.
Key Specifications

Pinout & Package
The SI86S630EE-AS2 is housed in a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance optimized for 6000 VRMS reinforced insulation. Pin 1 is marked with a dot; pins 1–8 constitute Side A (input side), pins 9–16 constitute Side B (output side), separated by an internal semiconductor isolation barrier.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 | Digital input | Active-high enable for all Side A outputs; places A1–A3 in high-impedance state when low. |
| VDD1, GND1 | Supply / Ground | Power and reference for Side A logic; requires 0.1 µF + 10 µF bypass capacitors per side. |
| A1–A3 | Digital I/O | Three bidirectional isolated channels on Side A; support Schmitt-trigger + CMOS thresholds for noise immunity. |
| NC | Not connected | Pin 6 is internally unused; must be left floating or grounded per layout best practices. |
| Isolation Barrier | Functional boundary | Physical and electrical separation between Side A and Side B; defines creepage/clearance path for safety certification. |
| B1–B3 | Digital I/O | Three corresponding isolated channels on Side B; electrically independent from Side A supply domain. |
| EN2 | Digital input | Active-high enable for all Side B outputs; places B1–B3 in high-impedance state when low. |
| VDD2, GND2 | Supply / Ground | Power and reference for Side B logic; galvanically isolated from VDD1/GND1. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | RF modulation architecture eliminates boot sequence delays-outputs follow inputs immediately after UVLO exit. |
| Selectable fail-safe mode | Ordering option determines default output state (high or low) during VDD1/VDD2 brownout-critical for safe system shutdown. |
| Tri-state outputs with enable | EN1/EN2 provide single-point control of all outputs per side-enables bus sharing and reduces contention in multi-master systems. |
| High electromagnetic immunity | 100 kV/µs common-mode transient immunity ensures reliable operation in high-dV/dt environments like IGBT gate drives. |
| Reinforced safety certification | UL 1577, VDE 60747-17, CSA 62368-1, and CQC GB4943.1 approvals validate suitability for medical and EV traction inverter applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3300ARWZ | 3-channel, 25 Mbps max data rate; 5000 VRMS isolation; SOIC-16 NB package; no AEC-Q100 qualification. | Suitable for non-automotive industrial control where lower speed and reduced isolation voltage are acceptable. | Choose ADUM3300ARWZ for cost-sensitive, non-safety-critical 3.3 V systems requiring basic isolation without high-speed or automotive compliance. |
| ISO6731DR | 3-channel, 50 Mbps max data rate; 5000 VRMS; SOIC-16 NB; IEC 60747-17 certified but not AEC-Q100 qualified. | Fits general-purpose isolation in programmable logic controllers and test equipment with moderate noise immunity needs. | Select ISO6731DR when CMTI >75 kV/µs suffices and design does not require 150 Mbps throughput or 6000 VRMS working voltage. |

FAQ
What is the maximum data rate supported by the SI86S630EE-AS2?
The SI86S630EE-AS2 supports a maximum data rate of 150 Mbps. This is specified under DC to 150 Mbps operation in the datasheet and validated across the full –40 to 125 °C temperature range with 2.25–5.5 V supply. The device achieves this using RF-based on/off keying, avoiding the bandwidth limitations of optocoupler or older capacitive isolator architectures. SI86S630EE-AS2 maintains signal integrity at this rate due to its 10 ns typical propagation delay and 3.5 ns pulse width distortion.
Does the SI86S630EE-AS2 require external configuration or initialization at power-up?
No, the SI86S630EE-AS2 requires no start-up initialization. Its RF modulation architecture enables immediate input-to-output functionality after exiting undervoltage lockout (UVLO), with a typical start-up time of 0.3 ms. Outputs follow inputs directly once VDD1 and VDD2 exceed their respective UVLO+ thresholds (~2.18 V). SI86S630EE-AS2 does not rely on internal clocks, firmware, or configuration registers-making it inherently deterministic and immune to soft errors.
What safety certifications apply to the SI86S630EE-AS2?
The SI86S630EE-AS2 holds UL 1577 recognition (6000 VRMS, 1 minute), VDE certification to IEC 60747-17 (reinforced insulation), CSA certification to 62368-1 and 60601-1, and CQC approval to GB4943.1. These certifications are validated for the WB SOIC-16 package and confirm compliance for use in medical electronics, industrial automation, and automotive onboard chargers. SI86S630EE-AS2 is also AEC-Q100 qualified for Grade 0 (–40 to +125 °C).
How does the fail-safe output mode work on the SI86S630EE-AS2?
The SI86S630EE-AS2 offers a selectable fail-safe mode determined at ordering-either default-high or default-low output when the input-side supply (VDD1) is unpowered but output-side supply (VDD2) remains active. This behavior is defined in Table 4 of the datasheet and enforced via internal circuitry that overrides output states during UVLO conditions. SI86S630EE-AS2 implements this without external components, ensuring predictable safe-state behavior during brownouts in motor control or BMS applications.
What is the purpose of the EN1 and EN2 pins on the SI86S630EE-AS2?
EN1 and EN2 are active-high enable inputs that place all outputs on Side A (A1–A3) and Side B (B1–B3), respectively, into high-impedance (tri-state) mode when driven low. This allows shared bus operation, reduces power consumption during idle periods, and prevents signal contention in multi-device configurations. Both pins are referenced to their respective side's supply (VDD1 for EN1, VDD2 for EN2), and internal pull-downs ensure defined states if left unconnected. SI86S630EE-AS2 uses these pins for deterministic output control without affecting isolation integrity.
