Design a Custom BoardAbout This Component
Solid-state photorelay switch using LED-driven MOSFET output for galvanic isolation. Rated 1A at 60V AC/DC with 0.18Ω on-resistance and 2500V input-output isolation. Offers bounce-free, noise-free switching ideal for telecom, data acquisition, medical equipment, and industrial control applications requiring high reliability and EMI immunity.
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.
