PHOTORELAY SPST 120MA 400V SOP-4


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSolid-state relay using integrated LED and photodetector for AC/DC load switching up to 400V and 120mA. Offers bounce-free operation, high EMI/RFI immunity, and unlimited mechanical lifetime compared to reed relays. Ideal for telecom, medical, industrial control, and safety systems requiring galvanic isolation with minimal power consumption.
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.
