The H11A1 is an industry-standard single-channel phototransistor optocoupler, manufactured by Fairchild Camera & Instrument. It comprises a gallium arsenide infrared LED and a silicon NPN phototransistor.
Key electrical characteristics include an input-output coupling capacitance of less than 0.5 pF and an isolation rated voltage of 4420 V RMS. These features enable reliable signal isolation in various applications.
The device is housed in a standard dual-in-line 6-pin package, suitable for through-hole mounting. The isolation performance is enhanced through Vishay's double molding isolation manufacturing process.
Applications for the H11A1 include AC mains detection, reed relay driving, switch mode power supply feedback, telephone ring detection, logic ground isolation, and logic coupling with high-frequency noise rejection.
