Product details
Overview
SI86S630EC-IS1 from Skyworks Solutions is a 3-channel, reinforced-isolation digital isolator with bidirectional signal transfer across an RF-based semiconductor barrier. It delivers DC–150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating in a narrow-body SOIC-16 package. It operates from 2.25–5.5 V supplies and supports fail-safe default-low output mode for industrial motor control and isolated ADC interfaces.
For engineers reviewing the SI86S630EC-IS1 datasheet, SI86S630EC-IS1 pinout, SI86S630EC-IS1 application, or SI86S630EC-IS1 equivalent, key selection criteria include its AEC-Q100 qualification, IEC 60747-17 reinforced insulation rating, tri-state output enable control, and precise timing performance under –40 to +125 °C ambient conditions.
Technical Context
The SI86S630EC-IS1 implements RF on-off keying modulation across a monolithic semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture integrates Schmitt-trigger inputs with CMOS thresholds and supports independent side-A/side-B undervoltage lockout (UVLO) with 2.10–2.25 V rising threshold and 1.98–2.12 V falling threshold.
It features dual active-high enable pins (EN1/EN2) controlling all outputs per side, selectable fail-safe default-low output behavior during unpowered input supply, and 100 kV/µs minimum transient immunity. The device requires only 0.1 µF and 10 µF bypass capacitors per supply rail and exhibits 50 Ω nominal output impedance for controlled-impedance PCB routing.

Pinout & Package
Narrow-body SOIC-16 (NB SOIC-16) package with creepage/clearance ≥8.0 mm and reinforced insulation barrier rated to 6000 VRMS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides isolated 2.25–5.5 V bias for channel inputs A1–A3 and EN1; requires local 0.1 µF + 10 µF decoupling. |
| A1–A3 | Side A digital I/O | Three unidirectional input channels referenced to VDD1/GND1; accept Schmitt-trigger + CMOS thresholds. |
| EN1 | Side A output enable | Active-high control that places B1–B3 outputs in high-impedance state when low; no effect on isolation barrier. |
| Isolation Barrier | RF-coupled dielectric | Semiconductor-based barrier separating side A and side B; enables galvanic isolation without optocoupler aging. |
| B1–B3 | Side B digital I/O | Three unidirectional output channels referenced to VDD2/GND2; drive 50 Ω loads with VOH ≥ VDD2–0.4 V. |
| EN2 | Side B output enable | Active-high control that places A1–A3 outputs in high-impedance state when low; independent of EN1 operation. |
| VDD2, GND2 | Side B power supply | Provides isolated 2.25–5.5 V bias for channel outputs B1–B3 and EN2; requires local 0.1 µF + 10 µF decoupling. |
Key Features

| Selectable fail-safe mode | SI86S630EC-IS1 is ordered with default-low output; ensures safe state during side-A power loss in motor control. |
| Tri-state output enable | EN1/EN2 pins allow dynamic bus contention management on isolated side without reconfiguring host controller. |
| High electromagnetic immunity | 100 kV/µs CMTI rating prevents false triggering in noisy inverter gate-drive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3210BRZ | 2-channel, 100 Mbps, 2500 VRMS, SOIC-8; no fail-safe option; higher quiescent current (1.2 mA/channel @ 5 V). | Limited to lower-voltage industrial PLC I/O modules; lacks AEC-Q100 qualification and 6000 VRMS rating. | Choose ADUM3210BRZ only if channel count and isolation voltage requirements are relaxed and cost sensitivity dominates. |
| ISO6731FDWR | 3-channel, 50 Mbps, 5000 VRMS, SOIC-16; failsafe default-high only; CMTI = 50 kV/µs; no sleep mode support. | Suitable for non-automotive industrial automation where lower data rate suffices and default-high fail-safe is acceptable. | Prefer ISO6731FDWR when system-level transient immunity requirements are less stringent and automotive qualification is not required. |
Compared with ADUM3210BRZ and ISO6731FDWR, the SI86S630EC-IS1 offers superior isolation voltage (6000 VRMS), higher speed (150 Mbps), AEC-Q100 qualification, and configurable default-low fail-safe-making it optimal for automotive OBC and high-reliability industrial inverters.

FAQ
What is the isolation voltage rating of the SI86S630EC-IS1 and which safety standards does it meet?
The SI86S630EC-IS1 is rated for 6000 VRMS isolation for 1 minute per UL 1577 and carries reinforced insulation certification per IEC 60747-17. It also meets CSA 62368-1 and 60601-1, and CQC GB4943.1 requirements. This rating is validated in the narrow-body SOIC-16 package and applies directly to the SI86S630EC-IS1 ordering option without derating.
Does the SI86S630EC-IS1 support fail-safe operation, and how is it configured?
Yes, the SI86S630EC-IS1 is manufactured with default-low fail-safe output behavior, meaning outputs B1–B3 go low when side-A supply (VDD1) is unpowered but side-B supply (VDD2) remains active. This configuration is fixed by the "EC" suffix in the part number and cannot be changed in-circuit; no external components or pins configure this mode.
What are the supply voltage requirements and bypassing recommendations for the SI86S630EC-IS1?
The SI86S630EC-IS1 operates from 2.25 V to 5.5 V on both VDD1 and VDD2 rails. Each supply requires a 0.1 µF ceramic capacitor placed adjacent to the pin and a 10 µF bulk capacitor within 10 mm. These values are mandatory per Skyworks' layout guidance and ensure stable RF modulation and low-noise output switching in the SI86S630EC-IS1.
How does the SI86S630EC-IS1 handle undervoltage conditions on either side?
The SI86S630EC-IS1 implements independent undervoltage lockout (UVLO) on VDD1 and VDD2, with rising threshold of 2.10–2.25 V and falling threshold of 1.98–2.12 V. When either supply drops below UVLO–, outputs enter a known state (low for SI86S630EC-IS1) via internal 100 kΩ pulldown; recovery time is 0.3 ms after VDD exceeds UVLO+.
Is the SI86S630EC-IS1 pin-compatible with other members of the Si86S6xx family?
No-SI86S630EC-IS1 has a dedicated 3-channel pinout (A1–A3, B1–B3, EN1, EN2) in SOIC-16 and is not pin-compatible with 4-, 5-, or 6-channel variants like SI86S640 or SI86S660. Pin mapping differs across channel counts, and EN1/EN2 placement is unique to the 3-channel S63x series per Figure 1 of the datasheet.
