Vishay TCLT1003 Optocoupler

The TCLT1003 is a 1-channel, 4-pin optocoupler featuring a phototransistor output with a current transfer ratio (CTR) suitable for microprocessor system interfaces. It consists of a gallium arsenide infrared-emitting diode optically coupled to a phototransistor, providing electrical isolation between input and output. This device offers high flexibility in CTR, a specialized construction, and very low coupling capacitance, making it ideal for use in power management, computer peripherals, and communication and networking applications. It operates with a DC input and has an integrated transistor output for reliable switching.
