Design a Custom BoardSingle-channel optoisolator combining an AlGaAs infrared LED with a silicon phototransistor detector, providing 3750V RMS isolation in a 4-pin SOP package. Features DC input with transistor output, 60mA forward current rating, and operating range of -55°C to 110°C. Ideal for switching power supplies, programmable controllers, and industrial equipment requiring galvanic isolation.
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.
