The PS2701-1-L with SOP-4 Optocouplers - Phototransistor Output ROHS manufactured by Youtai is an electronic component that utilizes a phototransistor output to provide electrical isolation between two circuits. This optocoupler is composed of a high power infrared LED optically coupled to a silicon NPN phototransistor. It is designed to provide a signal transfer from the input side to the output side with high linearity, wide response bandwidth, and low saturation voltage. The device offers low temperature drift, a long lifespan, and is RoHS compliant. It has a peak forward current of 50 mA, a collector-emitter voltage rating of 50V, and a storage temperature range of -40 to +85 degrees Celsius. This component is designed to be used in the control of high voltage loads, interfacing lower powered logic chips, and isolating low-level analog signals.
