Design a Custom BoardSingle-channel optoisolator with 3.75kV isolation voltage rating in 4-pin SOP surface-mount package. Integrates an LED on the input side coupled to a phototransistor output stage, providing galvanic isolation for logic-level signals across high-voltage boundaries. Commonly used in motor control, power supply feedback circuits, and industrial gate driver applications.
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.
