Design a Custom BoardAbout This Component
Single-channel optoisolator with Darlington output stage providing 3.75kV isolation voltage rating. Features a 4-pin SOP surface-mount package suitable for PCB integration in noise-sensitive applications. Commonly used for galvanic isolation between logic circuits and high-voltage/high-current switching stages, industrial control systems, and motor driver interfaces.
Package: SOP-4 (3.8×4.1mm, P2.54mm) · 4 pins
Why does this need a breakout?
This 4-pin SOP photorelay is too small and tightly pitched (2.54mm) for reliable hand soldering or breadboard use. A breakout board brings the pins to standard 0.1-inch spacing, enabling rapid prototyping of optoisolated switching circuits without the frustration of soldering microscopic leads or dealing with isolation requirements.
