SFH620A-2X007T

Optoisolators are electronic components that use optical links to isolate signals between two circuits. SFH620A-2X007T is a model of optoisolator, produced by OSRAM Opto Semiconductors Inc, and can be used for the applications of isolation, voltage surge and EMC (electromagnetic compatibility).

SFH620A-2X007T is a transistor, photovoltaic output optoisolator. It is a solid-state device which consists of an infrared LED and an integrated photodetector, housed in a small outer casing. Photodetector converts the incoming light from LED into electrical current. It is usually used for isolation, voltage surge protection, and EMC, and consists of a phototransistor-based output stage.

SFH620A-2X007T has a peak voltage rating of 500 volts, a CW (continuous wave) forward current rating of 5mA, and an output current rating of 300mA. Its phototransistor stage typically has an output on-state current of 400mA, a cutoff voltage of 5 volts, and an off-state leakage current of 10uA. Its spectral response range is 800 - 900nm. Its maximum on-state voltage rating is 100V, and its off-state leakage current rating is 500 nA.

The working principle of SFH620A-2X007T is based on optical isolation principle. When LED is turned ON, the generated light is absorbed by the photodetector, which then produces an electrical signal. This signal is then amplified by the phototransistor stage, and can be used to supply power to an external load. Depending on the external load, the electrical signal can either be a DC (direct current) or an AC (alternating current) signal. SFH620A-2X007T is considered to be an optically coupled signal isolator, as it can effectively isolate the input and output signals.

SFH620A-2X007T application field includes high pulse frequency switching power supplies, motor drive circuits, electrical transmission equipment, LED drive circuits, solid state relays and industrial controllers. It is widely used in industrial, commercial and medical applications. The applications include isolation of digital signals, power line isolation, isolation of high voltage signals and EMC (electromagnetic compatibility). SFH620A-2X007T can offer optimal isolation and performance in various applications.
