Design a Custom BoardAbout This Component
Solid-state relay with integrated photoMOS output for AC/DC load switching up to 60V and 2.5A. Features bounce-free operation, high-speed switching, low on-resistance (0.06Ω typical), and immunity to EMI/RFI. Ideal for telecom, medical equipment, battery monitoring, and industrial control applications requiring reliable electronic switching without mechanical contacts.
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.
