Product details
Overview
SI86S630EE-IS2 from Skyworks Solutions is a 3-channel, reinforced digital isolator with 6000 VRMS isolation rating, 150 Mbps data rate, and AEC-Q100 qualification for automotive systems. It features Schmitt-trigger inputs, tri-state outputs with enable, selectable fail-safe mode (default high/low), and operates across –40 to 125 °C in a WB SOIC-16 package. It is used in battery management systems and traction inverters where high noise immunity and safety-certified signal isolation are required.
For engineers reviewing the SI86S630EE-IS2 datasheet, SI86S630EE-IS2 pinout, SI86S630EE-IS2 application, or SI86S630EE-IS2 equivalent, key selection criteria include reinforced IEC 60747-17 certification, 10 ns typical propagation delay, 3.5 ns pulse width distortion, transient immunity ≥100 kV/µs, and dual supply operation (2.25–5.5 V per side).
Technical Context
The SI86S630EE-IS2 implements RF-based on/off keying modulation across a semiconductor isolation barrier-eliminating startup initialization and providing superior CMTI performance versus optocouplers. Its architecture supports independent undervoltage lockout (UVLO) and reset monitoring on both sides (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.
It integrates tri-state output control via EN1/EN2 pins, configurable fail-safe output state during unpowered conditions, and supports bidirectional signal isolation across three independent channels (A1–A3/B1–B3). The device uses CMOS thresholds with Schmitt-trigger inputs for robust noise rejection in industrial and automotive EMI environments.

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; 2.5 kVRMS isolation; no AEC-Q100 qualification | Targeted at industrial automation, not automotive-grade systems | Choose ADUM3300ARWZ only for cost-sensitive non-automotive designs requiring lower speed and reduced isolation rating |

FAQ
What is the isolation rating and safety certification status of SI86S630EE-IS2?
SI86S630EE-IS2 is rated for 6000 VRMS isolation per UL 1577 and certified to IEC 60747-17 (reinforced insulation). It holds pending CSA 62368-1 and 60601-1 approvals and CQC GB4943.1 certification. These ratings are validated for the WB SOIC-16 package and apply directly to SI86S630EE-IS2 as shipped.
Does SI86S630EE-IS2 require external initialization or configuration at power-up?
No, SI86S630EE-IS2 requires no start-up initialization due to its RF on/off keying architecture. Outputs become valid within 0.3 ms after VDD rises above UVLO+ (2.10–2.25 V), with internal 100 kΩ pulldown holding outputs low until stabilization. This behavior is intrinsic to SI86S630EE-IS2 and does not depend on external firmware or configuration.
How does the fail-safe mode operate on SI86S630EE-IS2, and how is it selected?
SI86S630EE-IS2 offers ordering-option-selectable fail-safe mode: default high or default low output state when VDD1 is unpowered but VDD2 remains active. This is implemented at silicon level and fixed per part number-SI86S630EE-IS2 is the default-low variant. No external circuitry or configuration is needed to activate this behavior.
What are the supply voltage requirements and bypassing recommendations for SI86S630EE-IS2?
SI86S630EE-IS2 operates from 2.25 V to 5.5 V on both VDD1 and VDD2 independently. Each supply requires a 0.1 µF ceramic capacitor placed adjacent to the pin and a 10 µF bulk capacitor near the device. These values are mandatory per Skyworks design guidelines and apply specifically to SI86S630EE-IS2's WB SOIC-16 layout constraints.
Can SI86S630EE-IS2 be used in bidirectional signal paths, and what are its direction capabilities?
SI86S630EE-IS2 provides three unidirectional channels (A1→B1, A2→B2, A3→B3) with no built-in direction reversal. For bidirectional isolation, separate forward/reverse channel pairs must be used. SI86S630EE-IS2 does not support dynamic direction control like Si86SQ44; its channel mapping is fixed and defined by the pinout in Figure 1 of the datasheet.
