Overview

The Si8610BC-B-IS is a single-channel digital isolator providing high-speed unidirectional data transfer with 3750Vrms isolation. Utilizing Skyworks' proprietary capacitive coupling technology, it supports data rates up to 150Mbps while maintaining high common-mode transient immunity (CMTI) of 35kV/us. This device is designed for robust performance in industrial environments with a wide supply voltage range from 2.5V to 5.5V.

Why Choose This Part

The Si8610BC-B-IS offers exceptionally low power consumption, drawing only 1.2mA per channel at 1Mbps, which minimizes thermal overhead in dense designs. Its high 150Mbps throughput and 35kV/us CMTI ensure reliable data integrity even in electrically noisy industrial environments.

Applications

Industrial Fieldbus Isolation
Protects sensitive microcontrollers from high-voltage transients in RS-485, CAN, or Profibus networks.
Isolated SPI/UART Communication
Provides high-speed signal isolation for logic-level communication between circuits at different ground potentials.
Switch Mode Power Supply (SMPS) Feedback
Facilitates isolated signal feedback between the secondary and primary sides of high-power converters.
Motor Control Logic
Isolates PWM control signals from high-voltage inverter stages to prevent noise injection into the control board.

Getting Started

Place the SOIC-8 package across a physical isolation barrier on the PCB, ensuring the recommended 3.75kV creepage and clearance distances are maintained. Connect 0.1uF bypass capacitors as close as possible to the VDD1 and VDD2 pins to ensure stable operation during high-speed switching.

Also Consider

ISO7710DWR TITexas Instruments - Offers a higher CMTI of 100kV/us and 5000Vrms isolation for more demanding surge environments.
ADUM110N0BRZ Analog Devices - Uses iCoupler transformer technology which may offer better immunity to certain magnetic field interference.
