Design a Custom BoardAbout This Component
Single-channel optocoupler with phototransistor output, featuring a GaAs infrared LED optically coupled to a phototransistor. Provides 5 kV isolation (VIORM = 1050 V) in a compact SMD SOP-4L package with low coupling capacitance. Ideal for switchmode power supplies, computer interfaces, and microprocessor system isolation applications.
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.
