H11A1 Description

Short technical summary and product information.

The GE Aerospace H11A1 is an industry-standard, single-channel phototransistor optocoupler. It integrates a gallium arsenide infrared LED with a silicon NPN phototransistor.

 

Key electrical specifications include an isolation rated voltage of 4420V RMS and an input-output coupling capacitance of less than 0.5 pF. These features make it suitable for various applications requiring signal isolation and noise rejection.

 

The device is housed in a standard dual-in-line 6-pin (DIP-6) package, designed for through-hole mounting. This packaging facilitates integration into existing circuit designs.

 

Applications for the H11A1 include AC mains detection, switch mode power supply feedback, telephone ring detection, and logic ground isolation. Its robust isolation performance is achieved through Vishay's double molding process.
