H11A1 Description

Short technical summary and product information.

The Vishay H11A1 is a single-channel optocoupler featuring a phototransistor output. It is constructed with a gallium arsenide infrared LED and a silicon NPN phototransistor, providing reliable signal isolation.

 

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

 

The H11A1 is housed in an industry-standard dual-in-line 6-pin (DIP-6) package, designed for through-hole mounting. It is available on tape and reel for automated assembly processes.

 

This optocoupler is designed to interface with common logic families and finds applications in areas such as AC mains detection, switch mode power supply feedback, logic ground isolation, and telephone ring detection.
