Design a Custom BoardAbout This Component
High-speed optoisolator featuring a Darlington output stage with base connection, designed for 3.75kV galvanic isolation. Typical switching speed of 1µs and current transfer ratio around 100-600%. Widely used in motor control circuits, power supply feedback networks, and isolated gate driver applications.
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.
