Product details
Overview
SI86SW62BC-IS1R from Skyworks Solutions is a 6-channel reinforced digital isolator with bidirectional signal isolation across an integrated semiconductor barrier, supporting up to 150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating. It operates from 2.25–5.5 V on both sides and is qualified per AEC-Q100 for automotive traction inverters and battery management systems.
For engineers reviewing the SI86SW62BC-IS1R datasheet, SI86SW62BC-IS1R pinout, SI86SW62BC-IS1R application, or SI86SW62BC-IS1R equivalent, this device delivers high CMTI (>100 kV/µs), fail-safe default-low output mode, Schmitt-trigger + CMOS input thresholds, and tri-state outputs with enable-critical for isolated gate drivers and SPI interfaces in high-noise EV power stages.
Technical Context
The SI86SW62BC-IS1R implements RF-based on-off keying modulation across a monolithic silicon dioxide isolation barrier, eliminating startup initialization and enabling deterministic timing without clock recovery circuits. Its architecture supports independent UVLO monitoring per side (VDD1/VDD2), RSTB reset threshold (~1.7 V), and fail-safe output state selection via ordering option.
It features dual supply domains with side-specific enable inputs (EN1/EN2), 50 Ω nominal output impedance, and internal 100 kΩ pulldown during unpowered states. The device includes Schmitt-trigger inputs for noise immunity and supports sleep mode via external control-though SI86SW62BC-IS1R itself does not include SMb pin functionality per family documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - enables high-speed communication in motor control feedback loops and isolated ADC interfaces. |
| Propagation delay | 10 ns typical - ensures tight timing alignment between controller and power stage in real-time inverter control. |
| Isolation rating | 6000 VRMS - meets reinforced insulation requirements per IEC 60747-17 for 1200 V DC bus systems. |
| Supply voltage | 2.25–5.5 V per side - supports direct interface with 3.3 V microcontrollers and 5 V gate drivers without level shifting. |
| CMTI | ≥100 kV/µs - prevents false triggering in high-dV/dt environments like SiC/GaN half-bridges. |
| Operating temperature | –40 to +125 °C - validated for under-hood automotive applications including onboard chargers and traction inverters. |
| Fail-safe mode | Default low output - ensures safe shutdown of downstream logic when primary-side supply fails. |
Pinout & Package
SI86SW62BC-IS1R is housed in a WB SOIC-16 package (wide-body, 10.3 mm creepage) with 6 isolated channels arranged as 3 forward (A→B) and 3 reverse (B→A) paths. Pin functions follow the Si86S66x series layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power domain | Supplies and grounds all A-side I/O; requires 0.1 µF + 10 µF bypass capacitors placed adjacent to pins. |
| A1–A6 | Side A digital I/O | Input/output terminals for forward-direction signals; compatible with CMOS/Schmitt thresholds. |
| VDD2, GND2 | Side B power domain | Independent supply for B-side logic; enables galvanic separation between MCU and power stage domains. |
| B1–B6 | Side B digital I/O | Corresponding isolated outputs/inputs; each pair (A1/B1, etc.) forms one bidirectional channel. |
| EN1, EN2 | Output enable | Active-high enables all outputs on respective side; drives outputs into high-impedance state when low. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and temperature drift issues of optocouplers; enables stable 150 Mbps operation over full temperature range. |
| Reinforced IEC 60747-17 rating | Validated barrier withstand capability supports functional safety compliance (ISO 26262 ASIL-B/C) in automotive powertrain systems. |
| Tri-state outputs with enable | EN1/EN2 allow single-point control of all A/B-side outputs-essential for bus arbitration in isolated SPI or CAN FD transceiver interfaces. |
| Schmitt-trigger + CMOS inputs | Combines noise immunity (hysteresis ≥0.15×VDD) with standard logic compatibility-reduces need for external filtering in noisy motor drive environments. |
| Fail-safe default-low option | Guarantees logic-low output during VDD1 loss-prevents unintended gate turn-on in isolated IGBT/SiC driver stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6601ARIZ-RL | 6-channel, 50 Mbps max, integrated isolated DC-DC converter (3.3 V out), 3750 VRMS rating | Preferred where auxiliary isolated power is needed; lower data rate limits use in high-speed gate drive feedback | Select when system-level BOM reduction outweighs need for 150 Mbps or 6000 VRMS |
| ISO6760FDWER | 6-channel, 50 Mbps, 5000 VRMS, 2.25–5.5 V supply, no fail-safe option, TI's capacitive isolation | Suitable for industrial PLC I/O modules but lacks AEC-Q100 qualification and reinforced certification for automotive traction | Choose for cost-sensitive non-automotive applications requiring basic 6-channel isolation without safety certification overhead |
Compared with SI86SW62BC-IS1R, ADUM6601ARIZ-RL trades bandwidth and isolation rating for integrated power, while ISO6760FDWER offers lower-cost isolation without automotive qualification or fail-safe defaults-making SI86SW62BC-IS1R the only option meeting full ASIL-C signal path requirements in 1200 V BEV inverters.

FAQ
What is the isolation rating and safety certification status of SI86SW62BC-IS1R?
SI86SW62BC-IS1R provides 6000 VRMS reinforced isolation per UL 1577 and is certified to IEC 60747-17. It also meets CSA 62368-1 and 60601-1, and CQC GB4943.1 standards. These certifications are fully documented in Skyworks' safety file and apply directly to the SI86SW62BC-IS1R part number in its WB SOIC-16 package configuration.
Does SI86SW62BC-IS1R support fail-safe output behavior, and how is it configured?
Yes, SI86SW62BC-IS1R is ordered with default-low fail-safe mode (indicated by "B" suffix in part number). When VDD1 is unpowered but VDD2 remains active, all B-side outputs are driven low-ensuring safe deactivation of downstream gate drivers. This behavior is hard-coded per ordering option and requires no external configuration.
What are the supply voltage requirements and bypassing recommendations for SI86SW62BC-IS1R?
SI86SW62BC-IS1R operates from 2.25 V to 5.5 V on both VDD1 and VDD2. Each supply must be decoupled with a 0.1 µF ceramic capacitor and a 10 µF bulk capacitor placed within 5 mm of the respective VDD/GND pins. This ensures stable operation under fast transient load conditions typical in motor control applications.
Can SI86SW62BC-IS1R be used in SPI isolation applications, and which pins map to SPI signals?
SI86SW62BC-IS1R is not a dedicated SPI isolator (like Si86SSxx), but its six independent bidirectional channels can route SPI signals: A1/B1 = SCLK, A2/B2 = MOSI, A3/B3 = MISO, A4/B4 = CS, leaving A5/B5 and A6/B6 for auxiliary signals such as interrupt or ready lines-enabling full SPI isolation without protocol-specific logic.
What is the maximum data rate and propagation delay specification for SI86SW62BC-IS1R?
SI86SW62BC-IS1R supports up to 150 Mbps data rate with 10 ns typical propagation delay and ≤3.5 ns pulse width distortion. These values are measured under standard conditions (VDD = 5 V, TA = 25 °C) and remain valid across the full –40 °C to +125 °C operating range per Skyworks' characterization data.
