Design a Custom BoardAbout This Component
Solid-state relay using photoelectric isolation for switching AC/DC loads up to 200mA at 60V. Features bounce-free switching, high EMI/RFI immunity, and no mechanical wear with unlimited electrical lifetime. Ideal for telecom, medical equipment, robotics, and industrial control applications requiring reliable, low-power triggered switching.
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.
