Design a Custom BoardAbout This Component
Single-channel optoisolator with 3.75kV isolation voltage rating in 8-pin SOIC package. Integrates an LED emitter and photodarlington transistor output for logic-level signal isolation. Suitable for industrial control, motor drive, and power supply applications requiring galvanic isolation between logic and high-voltage circuits.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
