Product details
Overview
SI8650ED-B-ISR from Skyworks is a five-channel, unidirectional digital isolator with high-side input (VDD1 side) and low-side output (VDD2 side), rated for 5 kVRMS reinforced insulation in wide-body SOIC-16 package. It supports DC–150 Mbps data rates, achieves ≤8 ns typical propagation delay, and operates across –40 to +125 °C with 2.5–5.5 V dual supplies. It is used in isolated gate drivers for traction inverters where robust noise immunity and fail-safe high-default outputs are required.
For engineers reviewing the SI8650ED-B-ISR datasheet, SI8650ED-B-ISR pinout, SI8650ED-B-ISR application, or SI8650ED-B-ISR equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade compatibility (AEC-Q100), and real-world isolation design context - including CMTI ≥50 kV/µs, tri-state enable control, and 5 kVRMS working voltage compliance per VDE 0884-10 and UL 1577.
Technical Context
The SI8650ED-B-ISR implements RF-based on/off keying across a semiconductor isolation barrier, eliminating startup initialization and enabling deterministic timing. Its architecture provides inherent Schmitt-trigger input hysteresis (0.44 V typ) and supports independent undervoltage lockout (UVLO) on both sides with 70 mV hysteresis.
All five channels are input-only on Side A (VDD1) and output-only on Side B (VDD2), with a single EN pin (EN2) controlling all five outputs. The device defaults to high-output state during power loss on VDD1 - a factory-configured fail-safe mode confirmed by its "ED" ordering code.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 5 unidirectional, A-side input → B-side output only |
| Max Data Rate | 150 Mbps - supports high-speed PWM feedback in motor drives |
| Propagation Delay | ≤8 ns typical - enables sub-10 ns timing-critical gate drive synchronization |
| Isolation Rating | 5 kVRMS reinforced - certified to VDE 0884-10, UL 1577, and IEC 62368-1 |
| CMTI | ≥50 kV/µs - sustains reliable operation in high-dV/dt inverter environments |
| Supply Range | 2.5–5.5 V per side - interoperable with 3.3 V logic and 5 V microcontrollers |
| Fail-Safe Default | High - ensures safe deactivation of downstream power stages during input-side brownout |
| Operating Temp | –40 to +125 °C - qualified for under-hood automotive and industrial ambient conditions |
Pinout & Package
SI8650ED-B-ISR uses a 16-pin wide-body SOIC (WB SOIC-16) package with 8.3 mm creepage/clearance, supporting 5 kVRMS reinforced insulation. Pin numbering follows standard SOIC convention (pin 1 = top-left corner, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Input-side supply | Power for channel inputs and internal transmitter; must be ≥2.5 V for valid operation |
| GND1 | Input-side ground | Reference return for VDD1 and all A-side signals; requires local 0.1 µF bypass |
| A1–A5 | Input channels | CMOS/Schmitt-trigger inputs accepting 0–VDD1 logic; no external pull-ups needed |
| VDD2 | Output-side supply | Power for output drivers and receiver; independent of VDD1 for true galvanic isolation |
| GND2 | Output-side ground | Reference return for VDD2 and all B-side signals; isolated from GND1 |
| B1–B5 | Output channels | 50 Ω nominal output impedance; drive CMOS loads directly or terminated transmission lines |
| EN2 | Output enable | Active-high control for all five B outputs; drives outputs to high-Z when low |
| NC | No connect | Pins 1, 9, and 16 are unconnected; may be left floating or tied to GND/VDD2 per layout needs |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation | Eliminates LED aging and temperature drift; enables stable 150 Mbps performance over full temp range |
| Tri-state enable (EN2) | Single-pin control disables all five outputs into high-Z - simplifies system-level power sequencing |
| Fail-safe high default | Guaranteed logic-high output when VDD1 is unpowered - critical for safe shutdown in BMS and OBC |
| Ultra-low power at 100 Mbps | 5.5 mA per channel @ 5 V - reduces thermal load in densely packed power modules |
| AEC-Q100 qualified | Automotive-grade process flow with PPAP support - meets zero-defect requirements for EV traction systems |
| 50 kV/µs CMTI | Withstands fast transients in 800 V battery systems without data corruption or latch-up |
Applications
| Motor Control Gate Driver | Battery Management System (BMS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8650ED-B-IS | Same silicon, identical specs, but in tape-and-reel (R-suffix) vs. cut-tape (no R); same WB SOIC-16 package and 5 kVRMS rating | No functional difference; selected for automated SMT assembly vs. manual/hand-solder prototyping | Choose SI8650ED-B-ISR for volume production with pick-and-place; SI8650ED-B-IS for lower-volume or evaluation use |
| ADUM141DARZ | Four-channel, 150 Mbps, 3.75 kVRMS, SOIC-16 narrow body; lacks fail-safe high default and AEC-Q100 qualification | Suitable for non-automotive industrial isolation where 5 kVRMS and fail-safe are not mandated | Select ADUM141DARZ only if channel count, cost, or footprint constraints outweigh reinforced insulation and automotive reliability needs |
Compared with SI8650ED-B-ISR, SI8650ED-B-IS offers identical electrical and safety performance in the same package but differs only in packaging format, whereas ADUM141DARZ trades 5 kVRMS reinforcement and fail-safe behavior for lower isolation rating and non-automotive qualification - making it unsuitable for EV traction systems requiring VDE 0884-10 compliance.

FAQ
What is the isolation rating and certification status of SI8650ED-B-ISR?
SI8650ED-B-ISR is rated for 5 kVRMS reinforced isolation and certified to UL 1577, VDE 0884-10, CSA 5A, IEC 62368-1, and GB4943.1. These certifications validate its suitability for safety-critical automotive and industrial applications where reinforced insulation is mandated - such as in ISO 26262-compliant traction inverters and medical power supplies.
Does SI8650ED-B-ISR support fail-safe operation, and how is it configured?
Yes, SI8650ED-B-ISR is configured for fail-safe high default output during VDD1 loss - a factory-set behavior indicated by the "ED" suffix. When the input-side supply drops, outputs B1–B5 remain logic high as long as VDD2 is powered, ensuring safe deactivation of downstream power devices. This is distinct from "EB" (fail-safe low) variants.
What is the role of the EN2 pin on SI8650ED-B-ISR, and how does it affect output behavior?
The EN2 pin on SI8650ED-B-ISR is an active-high enable that controls all five B-side outputs. When EN2 is high, outputs follow A-side inputs; when EN2 is low, all B outputs enter high-impedance state. This allows centralized shutdown of isolated signals without altering input states - essential for coordinated power sequencing in multi-rail systems.
Can SI8650ED-B-ISR operate with mismatched supply voltages on VDD1 and VDD2?
Yes, SI8650ED-B-ISR supports independent 2.5–5.5 V supplies on VDD1 and VDD2. For example, it can interface a 3.3 V MCU (VDD1) to a 5 V gate driver stage (VDD2) without level shifters. Input thresholds scale with VDD1, and output drive strength scales with VDD2 - enabling flexible mixed-voltage system integration.
Is SI8650ED-B-ISR qualified for automotive applications, and what documentation is available?
Yes, SI8650ED-B-ISR is AEC-Q100 qualified and built using automotive-specific manufacturing flows. It supports AIAG-compliant PPAP documentation, IMDS/CAMDS material declarations, and zero-defect methodology throughout production - meeting Tier-1 supplier requirements for battery electric vehicle (BEV) and hybrid electric vehicle (HEV) platforms.
